Refinery turnaround successfully completed


ILF has built up vast experience in the refinery business over the last decades. Trusting in our capabilities, one of ILF’s major clients asked our engineers to assist them with a turnaround in their refinery in Romania.

The maintenance work for this turnaround had to be completed within one month. While three projects only had to be completed, one of the projects had to be completely implemented within this short period of time. The ILF team completed more than 30 tie-ins for the ongoing tank construction projects during this month.

During the turnaround, ILF’s team of engineers was involved in all activities related to:

    • piping, mechanical, civil, electrical and instrumentation engineering
    • safety coordination
    • logistics

We are very proud to say that in the more than 3,000 hours of supervision and technical assistance provided by ILF, not a single incident occurred.

Extension of the Extra-High Voltage Grid in Zurich (SUI)


The Greater Zurich Area is currently much better connected to the Extra-High Voltage (EHV) grid from the North than it is from the South. In the North, the 220-kV grid extends as far as the city of Zurich. In the South, on the other hand, connection points are only connected to the city boundary with one 150-kV line each. Swissgrid therefore plans to connect the new Waldegg Substation to the EHV grid so that the EHV grid in future also extends as far as the city of Zurich from the South.

On behalf of @Swissgrid and @ewz, we – as part of the engineering consortium KiWa220 (c/o @ILF Consulting Engineers in Switzerland, @Suisseplan Ingenieure) – have been responsible, since February, for the overall project management of the planning and design of the new Waldegg Substation. From here, electricity will flow into the city of Zurich. The substation will be built underground to minimize its impact on the landscape and visibleness from the neighboring residential area as much as possible.

We would like to thank the client for the trust which they have placed in us and are pleased to be able to make a contribution to the security of electricity supply in the city of Zurich.

Hydrogen: Hyphen announces engineering partnership with ILF


Hyphen’s project is one of the largest green hydrogen projects globally, and will supply and decarbonise Namibia’s energy systems, as well as exporting to international markets. Hyphen is targeting annual production of one million tonnes of green ammonia by 2027, with plans to increase annual production to two million tonnes by 2029, cutting 5-6 million tonnes in CO2 emissions every year. Operating at full scale, Hyphen’s project could produce 350,000 tonnes of green hydrogen annually.

The project in Tsau // Khaeb National Park will act as a blueprint for future green hydrogen projects globally. Hyphen Hydrogen Energy (Hyphen) recently announced the signing of a partnership agreement with ILF Consulting Engineers (ILF) to support the delivery of its ground-breaking green hydrogen project.

As part of an integrated team, ILF will provide project management services and technical expertise to drive Hyphen’s project in Namibia, as well as procurement and contract advice. ILF will also provide implementation expertise in support of Hyphen’s socio-economic-development goals.

Marco Raffinetti, CEO of Hyphen Hydrogen Energy, said: “Our partnership with ILF marks an exciting step towards establishing Namibia as a world leader in the green hydrogen sector. ILF’s experience working on hydrogen projects across the world will be invaluable and will help Hyphen meet the project timelines and Namibia’s development objectives. “This appointment, combined with our engagement with potential consortium partners, shows there is massive interest in Namibia from those looking to invest in one of the world’s lowest cost and most advanced large scale green hydrogen projects. We look forward to working closely with ILF in the delivery of this transformative project.”

Dr. Michel Kneller, Director of Hydrogen at ILF, said: “We are proud to be a part of this significant lighthouse project. By providing our engineering and project management consultancy (PMC) services to this unique venture, we can contribute to the energy transition. Hydrogen plays a crucial role in transforming our energy system, and we are convinced it is key to a sustainable future.”

New hydrogen pipeline in Finland


ILF has signed a contract with Gasgrid Vetyverkot Oy, which was founded to promote the development of the Finnish hydrogen network, international infrastructure cooperation and the hydrogen market in Finland and the surrounding area.
The contract includes the basic design for a hydrogen transmission pipeline (approx. 23 km long) in Finland, along with a compressor station and related infrastructure. In addition, ILF will support the client in obtaining the necessary permits and agreements in consultation with local institutions.

The pipeline will transport hydrogen produced at the Kemira Oyj’s plant in Joutseno to the Ovako Imatra Oy Ab’s steel mill in Imatra.
This is the first hydrogen transmission project that extends beyond an industrial site.

The project will enable the implementation of the first complete hydrogen value chain in Finland, from electricity to hydrogen produced as a by-product in the chemical industry and to the end products of the green steel industry.

This will be the first step towards the development of domestic and international hydrogen-based markets and hydrogen transmission infrastructure.

Start of design works for railway tunnel in Frankfurt/Main (GER


As part of the engineering consortium ʺIngenieurgemeinschaft Fernbahntunnel Frankfurt am Mainʺ, ILF has been tasked with designing/producing the preliminary design for a new tunnel and new underground station for long-distance traffic beneath Frankfurt’s terminus station. ILF is significantly involved in the technical design of the tunnel structures, emergency exits and bifurcation structures in connection with the underground station.

Once the future tunnel has been commissioned and goes into operation, the majority of long-distance trains will be able to approach the new station through the tunnel. This will not only eliminate the bottlenecks at Frankfurt’s existing main station, but will also allow local and regional public transport to flow more smoothly into the main station, as well as enable the expansion of local and regional public transport services as required.

Of the three corridors examined in the feasibility study, the Southern Corridor was the corridor option to be chosen. The advantage of this option is that the future tunnel can be connected to the existing railway lines in the direction of Hanau at two separate points. These connections will mean that all trains heading in this direction will be able to run at optimum capacity, and traffic can be better distributed over the existing routes. To the West, the tunnel will be connected to the planned third Niederrad Bridge.

ILF Supports Shell’s Solar For Schools Initiative


Shell has signed a Memorandum of Cooperation with the Ministry of Energy in Kazakhstan to help Kazakhstan achieve its energy transition targets. Under this memorandum, Shell has implemented the ʺSolar for Schoolsʺ initiative at the Nazarbayev Intellectual Schools (NIS), which has involved the installment of grid-connected solar PV systems at five schools across Kazakhstan.

Shell contracted ILF as an Owner’s Engineer to supervise all the technical aspects of this project. This supervision has involved performing the following tasks:

    • Providing support with project development
    • Conducting a study to assess the economic benefits of the solar PV installations
    • Providing support with the EPC tender
    • Assisting with EPC engineering and pre-construction activities
    • Providing support with EPC construction and commissioning

The installed PV systems cover up to 30% of the schools’ annual electricity consumption and feed any surplus electricity that is generated by the system into the municipal grid, generating significant savings. In addition, the project aims to encourage and promote Science, Technology, Engineering and Mathematics (STEM) education among younger generations and to raise awareness of the benefits and new opportunities associated with the use of renewable energy.

The first school to benefit from this project was the NIS School of Physics and Mathematics in Astana in 2018. Now, in 2023, the last of the five schools has received its PV system.

The ILF teams in Kazakhstan and Germany combined their global solar expertise and knowledge of local standards and regulations and are proud to have led this project to success.

Hydropower Plant inauguration on the Weerbach (AUT)


The Gemeinschaftskraftwerk Weerbach (GKW) Hydropower Plant was inaugurated at the end of June.
​​​​The GKW Hydropower Plant uses the natural hydraulic power of the Weerbach stream. Water is fed via a water intake structure, located at around 1,500 masl, and an approximately 4-km-long penstock, to the power house, located at around 1,100 masl. At the power house, a Pelton turbine with a capacity of 1.7 MW generates around 7.5 gigawatt hours of electricity per year, which is fed into two grids via a 25 kV and/or 10 kV transmission line.

After flowing through the turbine, the water is fed into the intake of the downstream hydropower plant, where it is used once again to generate electricity. A second option would be to discharge the water leaving the turbine directly into the Weerbach stream so that the GKW Hydropower Plant can also be operated independently of the existing downstream hydropower plant.

In the residual flow section at the GKW Hydropower Plant, discharge into the Weerbach stream is varied as ecological flow to ensure compliance with ecological requirements and to maintain the hydrological and environmental balance in accordance with the granted permit.

The short construction period of around one year is remarkable and was only possible thanks to the extremely cooperative relationship between all those involved.
We are proud to have been able to successfully complete our work on this complex project, and warmly congratulate all those involved.

Sludge Management in Za’atari Refugee Camp (JOR)


Za’atari Camp is located in the Jordanian desert, about 10 km west of the city of Al Mafraq. Since its establishment in 2012, the camp has developed into an urban settlement, and is currently home to about 80,000 people, most of them refugees who have fled from the civil war in their home country of Syria. While the sanitation system in the camp has gradually evolved over time with the provision of a camp-wide sewer system and a wastewater treatment plant, the sludge management currently practiced is based on the transportation of liquid sludge over long distances by trucks and sludge disposal in remote areas.

In 2022, ILF was contracted to provide consulting services aimed at improving sludge management in Za’atari Refugee camp in an environmentally friendly and cost-effective manner. This multi-donor action is jointly co-financed by the EU Regional Trust Fund in Response to the Syrian Crisis (EUTF Syria) and the German Federal Ministry for Economic Cooperation and Development (BMZ), and is being implemented by GIZ. Under the contract, ILF and its local partner Engicon have produced three main deliverables: 1) a Pre-Feasibility Study, 2) a Feasibility Study and 3) Tender Documents for Consulting Services covering the Conceptual Design, Tendering and Construction Supervision.

The objective of the preliminary studies was to establish baseline conditions and data, identify and evaluate options for sludge management, and select the preferred option. The preferred option that was selected was greenhouse sludge drying in conjunction with a series of upstream sludge treatment facilities at the existing wastewater treatment plant. Consultations and workshops with stakeholders were critical to the decision-making process regarding selection of the preferred sludge management option.

We would like to thank all stakeholders (including the EU, the German government, GIZ, UNICEF, UNHCR, WAJ, Yarmouk Water Company, Oxfam and the FAO amongst others) for their joint support in this assignment and wish them every success for the implementation of the project!

Safe storage solution for crude oil


ILF Consulting Engineers has always been deeply involved in the design and management of projects involving storage tanks. It is therefore no surprise that, in recent years, the team at ILF Romania has been working on a project involving a large capacity crude oil storage tank – providing services from the design phase through to the construction management and supervision phase. The crude oil storage tank at the center of the complex project, which started several years ago with a solution and capacity selection study, has a capacity of 60,000 m3 and has been designed based on one of the safest storage solutions in the oil and gas industry in terms of environmental impact and operational safety.

This Engineering, Procurement and Construction Management (EPCM) project, entrusted to ILF Consulting Engineers in Romania since the feasibility phase, has now reached the construction phase (half of the construction period has already passed) and is already showing some quite impressive results.

The design currently being realized has been developed up to the detailed designed phase, and for that the whole team has produced a complete set of documentation including workshop drawings for every detail.

The tank has a double shell and a double bottom, a full contact internal floating cover, which fulfills the role of retaining at least 98% of the vapor emissions, and a fixed aluminum dome cover. The outer shell replaces the retention basin, and the double bottom enables possible leaks to be monitored.
The tank is also equipped with a product heating system (steam coil), a homogenization system (3 mixers on the inner shell) and a system for product sampling at certain levels.

In this context, Adrian Stoica (General Manager of ILF in Romania) would like to express his special thanks to the entire team of ILF Romania for the excellent engagement and dedication during this project.

Technical Specifications for Wastewater Treatment in Saudi Arabia


The preparation of specifications for wastewater treatment will benefit the people of Saudi Arabia for years to come and is in line with the Kingdom’s strategy to provide water and wastewater treatment services of the highest quality. The decision to implement high-quality solutions that meet the Kingdom of Saudi Arabia’s water management needs is a major step towards Saudi Arabia’s Vision 2030 regarding water quality, sustainability and environmental protection.

The National Water Company (NWC) has commissioned ILF to develop the following documents:

    • Technical Specifications
    • Design Manual Guideline – for the wastewater system, sewage pumping stations, force (pressure) mains & TSE network
    • Typical drawings/data sheets for mechanical, electrical & control, automation & integration philosophy

The specifications shall consider a number of criteria related to the infrastructure’s ability to ensure operational efficiency. Preparation of such specifications involves assessing the extent to which they can ensure high output performance, a certain redundancy configuration, durability and maintainability. The specifications are also being developed to ensure the required level of safety throughout the infrastructure’s operational life.

SUEDLINK: Stakeholder involvement as a piece in the puzzle


Infrastructure Projects: Stakeholder involvement as an important piece in the puzzle

And how are things progressing with SuedLink, one of Germany’s biggest energy transition projects?
The first works on the route corridor are scheduled to begin in autumn 2024, so that by 2028, electricity will be able to flow from the wind farms in northern Germany to the major centers of consumption in southern Germany.
Today, energy transition projects with complex and long-term impacts on society, the environment and economy are reliant on the early involvement of stakeholders. Participatory processes (stakeholder engagement) are immensely important for the successful implementation of this major infrastructure project. The engagement process for SuedLink was therefore on TenneT and TransnetBW’s (the project developers’) agenda from the very beginning, with the aim of integrating landowner’s and the local community’s concerns. During project preparation and development for the southern permit application section E2 – Baden-Württemberg – iterative dialogues with stakeholders were held on two occasions. In the course of submitting the permit application documents in March 2023, six discussions were also held in a third round of dialogues with affected individuals, communities, companies and municipalities in Baden-Württemberg. By engaging in these comprehensive dialogues at such an early stage, potential conflicts can be identified, concerns can be raised, and, finally, joint solutions can be found. ILF Consulting Engineers is engaging in dialogues with clients and is supporting the dialogues with owners with the help of knowledge carriers from various technical departments.

Opening of the new tunnel tube for the Gubrist Tunnel (SUI)


The Zurich Northern Bypass is one of the busiest sections of motorway in Switzerland and is reaching its capacity limits. An expansion of the Northern bypass and the construction of a third tunnel tube in the Gubrist Tunnel shall accommodate increased traffic volumes. The third tube has now been opened and traffic is travelling through this new third tube of the Gubrist Tunnel.

Together with WSP Ingenieure AG and Amberg Engineering, ILF is in charge of the tunnel ventilation and thus plays a major role in the expansion of the Zurich Northern Bypass. Tunnel ventilation is a key safety component in a road tunnel and allows tunnel users to escape safely from the tunnel in the event of a fire. The tunnel ventilation system in the third tube of the Gubrist Tunnel consists of 4 exhaust air fans, 34 dampers, 12 jet fans, various ventilation sensors, 179 control cabinets and more than 80 km of cable.

With the completion of the new third tube, refurbishment of the two old tunnel tubes of the Gubrist Tunnel can now start.

Improving sustainability in world’s largest undersea road tunnel


In Norway, the Norwegian Public Road Administration, Statens Vegvesen, is currently building the E39 Rogfast Project. This project, located North of Stavanger, involves the construction of the twin-tube Boknafjord Tunnel, which, when complete, will be the longest and deepest undersea road tunnel in the world being 26.7 km long and 390 m below sea level at its deepest point.

In addition, the Rogfast Project has been selected by Statens Vegvesen as a pilot project to help reach their CO2 targets through the use of electric-powered heavy construction machinery. Statens Vegvesen has commissioned a consortium consisting of ILF Consulting Engineers in Norway, ILF Consulting Engineers in Austria, Graz University of Technology (Austria) and Sovik Consulting (Norway) to carry out a risk assessment for the use of electric-powered vehicles, commonly referred to as Battery Electric Vehicles (BEV s), in the E39 Rogfast Project.

The aim of this study is primarily to investigate potential fire risks associated with the use of battery-powered heavy vehicles for the transportation of excavated rock.
These fire hazards could arise, for example, from overloading during heavy use or from recharging the vehicles. The impact of these vehicles on the construction process and their practical implementation will also be investigated.
With delivery of this service, the consortium is making a targeted contribution to one of the largest tunnel projects ever to be built in Norway and to the sustainability of tunnelling in general.

BorWin4 and DolWin4 – milestone for the “Süd” onshore section


A significant milestone has been reached for the DolWin4 and BorWin4 offshore grid connection systems.

DolWin4 and BorWin4 connect the large wind farms in the North Sea with the onshore transmission grid. The connection points are located in North-West Germany and the onshore connections are planned to be implemented as underground cables.

The project developer Amprion GmbH has taken an important step towards obtaining a building permit by submitting the application for official plan approval. For the southernmost section of the onshore route of the two grid connection systems, all documents have been submitted to the respective authorities on time. This paves the way for the next steps and brings the project developer closer to receiving the final decision from the approval authority.

ILF significantly contributed to the success of this project with the timely delivery of the technical design. The fact that the schedule was successfully met, at all times, is the result of all project parties cooperating very effectively with each other and the trust built up between the service provider and client.
We look forward to continuing to assist the project developer, applying our expertise in this project.

ILF designs a bypass tunnel for a Swiss municipality


To reduce the amount of through traffic in the Swiss municipality of Näfels, a bypass is planned to the North. ILF, as part of the IG Niederberg, and together with B+S, is involved in the design works for the bypass tunnel.

When complete, the 2.8-km-long Näfels bypass will consist of a 700-m-long section of open road in the North, the 1.8-km-long Niederberg Tunnel and a 300-m-long section in the South with a new junction connecting the bypass to the existing cantonal road.

ILF and its partner are responsible for the construction design and detailed design of the two-lane Niederberg Tunnel, which shall be operated as a two-way traffic tunnel. We would like to thank ASTRA, the Swiss Federal Roads Office, for the contract and are very much looking forward to carrying out this exciting task.

H2: Point Tupper Green Hydrogen/Ammonia Project


The Point Tupper Green Hydrogen/Ammonia Project is considered one of the most advanced projects for the large-scale production of green ammonia. The aim of the project is to produce certified green hydrogen and ammonia to meet increased global demand. This project also makes it possible to reduce the amount of CO2 emissions compared to the amount emitted from conventional ammonia production processes.
EverWind Fuels plans to deliver certified green hydrogen to German offtakers by 2025. Supplying the German market with green hydrogen is an important goal of the historic hydrogen alliance between Canada and Germany. The agreement was signed in August 2022 and contributes to achieving climate targets.

ILF is pleased to be able to support EverWind Fuels in this pioneering project as a Project Management Consultant (PMC).
​​​​​​​We will also lend technical support to EverWind Fuels and perform the Design Review for the EPC Contractor.

For the initial phase of green hydrogen and green ammonia production (200,000 tonnes per year), EverWind has received environmental approval from the Canadian Ministry of Environment and Climate Change for their project, with an investment volume of more than USD 1 billion.
Construction of the hydrogen and ammonia production plant is planned to commence in 2023, on an industrial site at Point Tupper in Nova Scotia, Canada. The jetty at the existing EverWind Fuels’ tank farm will be used to load the ammonia onto ships.
In the first phase, certified green electricity will be used. This electricity will mainly come from newly installed regional wind farms and will be transported via the public grid. In a second phase, the facility will be significantly expanded and for this purpose, separate 2GW wind farms will be developed.

Water: Supply Quality Improvement Program in SAU


The National Water Company (NWC) of Saudi Arabia is addressing the problem of high salinity levels in the drinking water in six cities in the Eastern region of the country through a new program. The NWC plans to construct transmission lines with a total length of 520 km, 21 pumping stations and 42 storage tanks. In addition, the overall network will be extended to serve new areas and old pipelines will be replaced to reduce water losses.

An additional 420,000 m3/day of water is needed from alternative sources before all of the existing groundwater wells which have high salinity levels can be closed, and to cater for the future demand of 1,370,000 m3/day. This additional water will be supplied by the Saline Water Conversion Company (SWCC KSA) in Saudi Arabia.

The NWC has entrusted ILF with the project management, construction supervision, and  design review services for this program – the currently biggest urban water supply program in Saudi Arabia.

ILF continues advisory to Red Sea Global


Red Sea Global, the developer of the world’s most ambitious regenerative tourism destinations, has appointed ILF as an Independent Engineer for the implementation phase of the primary utility system currently being developed by a consortium led by ACWA Power.
The project includes the provision of renewable power, potable water, wastewater treatment, district cooling and solid waste treatment for 16 hotels, an international airport, and infrastructure that will form Phase One of The Red Sea destination in Saudi Arabia.

Key Facts: 

  • Solar PV: 340 MWac
  • BESS: 1,200 MWh
  • Internal Combustion Engine: 108.98 MW
  • SWRO: 32,500 m3/day
  • Wastewater: 18,300 m3/day
  • District Cooling: 32,500 RT
  • Solid Waste Management: 11,775 T/year

ILF already acted as a technical advisor during the tendering stage of the PPP project, which resulted in a Utilities Concession Agreement (UCA) worth roughly USD 1.5 billion.
The extension of ILF’s involvement in this landmark development is seen as both an expression of confidence as well as a confirmation of the call for ILF to continue to deliver Engineering Excellence with ILF’s integrated team from its offices in Saudi Arabia, Austria, Germany and Poland.

Designing the backbone of European hydrogen infrastructure


A large part of Northern Germany’s wind energy potential cannot currently be used due to bottlenecks in the power grid.
The aim is to be able to utilize this unused wind energy potential in the future by converting it into green hydrogen with the help of power-to-gas facilities.
Transporting gaseous hydrogen in pipelines has clear advantages – technically, economically and ecologically – in comparison to other transport options.

In this context, HyPerLink, Gasunie’s envisaged approximately 66-km-long hydrogen network, and a key part the future European hydrogen network, shall provide an efficient link between the Netherlands, Germany and Denmark. A particularity of this project is that the HyPerLink will be developed mainly by converting already existing natural gas infrastructure into hydrogen infrastructure with a capacity of up to 7.2 GW. ILF has been commissioned by Gasunie for the “Project design and project management for the modification of existing pipeline infrastructure in HyPerLink Phase I and Phase II”.

This gives ILF the opportunity to participate in one of the European hydrogen industry’s lighthouse projects.
The project for which an application for early commencement of measures has been submitted, is awaiting notification from the IPCEI program.

ILF aims to become ‘Net Zero’


ILF has committed itself to becoming ‘Net Zero’ by 2040.

Becoming ‘Net Zero’ first and foremost means reducing, reducing and (once again!) reducing emissions. In line with the Science Based Target Initiative, we are following the pathway towards achieving net zero emissions by making ambitious efforts to reduce our overall greenhouse gas emissions by at least 90% by 2040, and by offsetting a maximum of 10% of our remaining, unavoidable emissions.

How will ILF become Net Zero by 2040?

Having set ourselves near-term targets for 2030 and committed to achieving net zero emissions by 2040, it is now time to take concrete steps to reach this ambitious goal. The Sustainability Team at ILF has therefore organized for a number of Net Zero workshops to be held, where colleagues from all levels of the ILF hierarchy will be able to share their ideas and together formulate specific goals and measures to be taken at their ILF location. In view of our current carbon footprint, special attention will be given to ILF’s “top three” emission sources: Business Travel by Aircraft, Business Travel in Company Vehicles and Employee Commuting.

At ILF, we know that achieving net zero emissions by 2040 in line with the Science Based Targets Initiative is an ambitious goal, but we are ready and willing to do whatever it takes to reach this goal!

Converting an old coal mine into a renewable energy hub


The Glenmuckloch Energy Park (GB-SCT) project entails the conversion of a disused open-cast coal mine into a renewable energy hub. This Energy Park will involve the development of both a 210 MW Pumped Hydroelectric Energy Storage (PHES) plant and a 33.6 MW wind farm on the same site.

During its previous operation, the Glenmuckloch mine was contributing to the greenhouse gas emissions associated with coal-powered energy generation. The envisaged Glenmuckloch Energy Park will serve the purpose of actively reversing these impacts, by contributing to the transition from thermal to renewable energy generation.

The former mining operations at Glenmuckloch created a significant void in the ground, which is to be used as the lower reservoir. Approximately 220 m above the lower reservoir, a new turkey’s nest reservoir will be constructed. The two reservoirs will be connected by an above-ground steel penstock entering a shaft powerhouse located adjacent to the lower reservoir. The PHES will be able to provide approximately 1,600 MWh of renewable energy per cycle.

As part of the decommissioning process for the mine, the entire Glenmuckloch area will need to be rehabilitated. Instead of allowing the mine to become a dormant asset, the conversion of the site into a renewable energy hub will not only provide energy security for the region, but will also help to create jobs for the local communities.

ILF, together with the lead partner Ove Arup & Partners Limited (Arup), has been appointed as the Owner’s Engineer for the development of this project. Arup will oversee the full development of the wind farm project components, while ILF has been engaged as a specialist sub-consultant to oversee the development of the PHES project components. The project is being financed by the Foresight Group (Foresight), a sustainability-led alternative assets and SME investment manager.

CAN – EU: Transport of hydrogen by sea


The European Union has declared that hydrogen – and its derivatives, such as ammonia and methanol – are key to achieving the Union’s legally binding obligations to reduce net greenhouse gas emissions by at least 55% by 2030 (compared to 1990 levels) and to become climate neutral by 2050.

As Europe is unable to produce sufficient quantities of hydrogen for its own needs, imports from overseas are currently the subject of many detailed investigations.

Late last year, political leaders from Germany and Canada entered into a hydrogen alliance, based on the idea of exporting clean hydrogen to the EU in order to help reduce the need for natural gas imports. Shortly after the alliance was formed, ILF began working on two techno-economic studies on Canada’s readiness to transport hydrogen products by sea from Eastern Canada to Europe.
ILF’s involvement in these studies is an example of one of the contributions that ILF is making towards a sustainable future for our planet.

BBT Feeder Line North – ILF receives contract for new section


Within the scope of work for the new twin-track Feeder Line North of the Brenner Base Tunnel, DB Netz AG has commissioned ILF Consulting Engineers, as part of an engineering consortium with two other partners, to carry out the route design and project planning works for the preliminary design of the Grafing–Ostermünchen (GER) section.

Currently under construction, this section forms part of the Feeder Line North of the Brenner Base Tunnel which is an integral part of the Scandinavian–Mediterrranean Corridor (Scan–Med Corridor) from Finland to Malta. This corridor is also the most important North–South Railway Link in Europe. The approx. 15-km-long section comprises the northernmost part of this project. In addition to open-track sections, associated traffic infrastructure, bridges and tunnels are also planned.

The Building Information Modelling (BIM) method is being used during the design which also includes an option for further design phases (conceptual design, permit application design and tender design).

Having already been involved in the previous design phase for this section (namely the route selection procedure), ILF has detailed knowledge of the local site conditions and can therefore support this complex project in the further design phases.

Water for Jordan


With less than 100 m³ of renewable water resources per capita and per year, Jordan is one of the most water-scarce countries in the world.
The existing water resources are already heavily overexploited and are rapidly being depleted as a result of supplying a growing population. The water sector in Jordan is characterized by high water losses and low cost coverage.

To tackle the challenges associated with water supply in Jordan, the Water Authority of Jordan (WAJ) has commissioned a joint venture, consisting of ILF and Engicon, with the project “Energy Efficiency in the Water Sector II in Jordan”. The focus of this project is on reducing the amount of non-revenue water, such as leakages or illegal connections, as well as reducing the carbon footprint of the water sector in general.

A multi-pronged approach has been chosen to make every drop count. Five selected pumping stations will be rehabilitated, mainly by replacing inefficient equipment such as pumps, fittings and valves. To ensure a more sustainable operation of the water network, an additional booster pumping station will be constructed. Furthermore, the water network itself will undergo several changes in order to make the best use of the mountainous terrain.

Measures which increase energy efficiency in the water sector are both environmentally and economically beneficial for all parties involved.

The rehabilitation of the pumping stations and the restructuring of the water supply network are projected to save more than 9,000 metric tons of CO2 emissions annually.

Energy demand can be lowered by approximately 50%, and, in addition, up to 20% of physical water losses are expected to be eliminated.

Phase 1 of the construction works has recently started and is expected to be completed in 2025. Phase 2 is currently out to tender.

Urban Railways eases commuter traffic (Linz/AUT)


ILF has won the contract for project management, development and design, including management of all environmental issues, for the Linz Urban Railway, Austria.

The metropolitan area of Linz (in the province of Upper Austria) has a number of hospitals, universities, cultural and administrative facilities and offers more jobs than there are inhabitants (> 200,000). As a result, Linz has been struggling with commuter traffic for a long time.

A high-quality alternative to private transport is therefore needed and a new public transport solution is being developed. The key objectives are to provide high-quality transport for passengers, fast travel times, direct connections to high-level institutions and links to the existing infrastructure: the Linz Urban Railway.

ILF was commissioned by Schiene OÖ GmbH, together with a local partner in Linz, to prepare the documents for the preliminary design of all the technical and environmental aspects and to clarify the necessary legal proceedings for all sections of the Linz Urban Railway. Planning for the approval procedure and the environmental impact assessment for the urban railway’s connection to the university is an optional part of the contract.

Ski Area Expansion in New Zealand – The Remarkables


NZSki, one of New Zealand’s ski field operators, plans to increase the capacity of its ski area ”The Remarkables” near Queenstown from its current capacity of approx. 3,500 skiers to a future capacity of approx. 7,500 skiers. For the proposed plans to become reality, the neighboring bowl, the Doolans Basin, shall be developed into a ski area. To achieve this, various options will be investigated in a masterplan and a development strategy will subsequently be formulated.

ILF Consulting Engineers has been entrusted with preparing this masterplan which covers slopes, ropeways, snow-making systems, ski tunnels, parking facilities, mountain restaurants, maintenance and service infrastructure as well as connections to the existing ski area. The masterplan will also encompass all the construction measures required to operate the ski resort following the increase in capacity.

Tunnel safety and security with AI


Digitalization poses new challenges to be faced in road tunnels – challenges which require interdisciplinary action.

Coordinated by the Federal Highway Research Institute (“Bundesanstalt für Straßenwesen” GER) and ILF, the bilateral research project Artificial Intelligence for Improvement of Safety of Tunnels and Tunnel Control Centers (“KITT”) is developing innovative solutions. By using data from Cooperative Intelligent Transport Systems (C-ITS) as well as Artificial Intelligence (AI), hazardous situations in tunnels, or anomalies in IT security, can be recognized more quickly and reliably.

ILF is proud to be able to apply its extensive experience of performing risk analyses in road tunnels and its own (self-developed) tunnel risk model TuRisMo to improve existing methods by using C-ITS technology.
The research project is being funded by the Security Research Funding Program (“KIRAS”) set up by the Austrian Federal Ministry of Agriculture, Regions and Tourism (“BMLRT”) and the German Federal Ministry of Education and Research (“BMBF”) as part of the call for Artificial Intelligence in Civil Security Research (“Künstliche Intelligenz in der zivilen Sicherheitsforschung”).

Extending the 2nd S-Bahn Main Line in Munich (GER)


As part of a joint venture (JV), ILF has been awarded the contract for the preparation of tender documents for the Eastern Section of the 2nd S-Bahn Main Line in Munich.

This section of the line comprises approx. 3.4 km of tunnels, one underground halt and several civil engineering structures. ILF has also been involved in the design of the Western Section of the line since 2017. As part of different JVs, ILF was commissioned with the final design and the permit application design services for the overall project, the preparation of tender documents and construction design services for two underground halts.

The overall project, with a line length of approx. 10 km, contains a tunnel section with a length of approx. 7 km and three underground halts (with lengths between 230 m and 250 m, and a depth of approx. 45 m). The tunnels – two tunnels and one emergency tunnel – will be driven mainly by TBMs. The underground halts are being constructed using the cut-and-cover method, and for the platform tunnels, the New Austrian Tunneling Method (NATM) is being used.

The Deutsche Bahn has taken the decision to extend the underground section of the line under the city center (by adding a new line beneath the existing one) because the S-Bahn Main Line in Munich was no longer able to handle today’s passenger numbers.


ILF designs the widest tunnel portals in its history (Linz/AUT)


ILF is pleased to be able to present the design for the tunnel portals with the widest span in the company’s more than 55-year history.
As the leading partner of a planning consortium, ILF, on behalf of ASFINAG, has been working on the detailed design for the tunnel structures within phase 1 of the A26 motorway construction project near Linz.

The motorway tunnel constructed in phase 1 of the project has four lanes in some sections and a total length of 2.4 km, including access and exit ramps. The two main portals of the tunnel deserve special attention: The portals of the two main carriageways, which shall directly adjoin the fourth Danube bridge on both sides, span a width of about 25 m and have a shotcrete thickness of only 60 cm. The operating rooms are located directly below these main portals.

Overcoming the challenge of designing and finally realizing tunnel portals of these dimensions has only been possible thanks to ILF’s partnership with ASFINAG and the joint venture ARGE A26 that is responsible for executing the project.

Thank you for the excellent cooperation!

ILF increases safety on Swiss transit route


ILF has been commissioned as part of an engineering consortium (INGE Axe Bauleitung) for the construction supervision for the new Axenstrasse road project. The project is expected to run until the end of 2033.

The Axenstrasse road was built between 1861 and 1865 and is located in Central Switzerland. The road has been damaged several times by rockfalls and mudslides, which is why a new Axenstrasse road is now being built.

ILF has commenced its construction supervision work at the Gumpisch temporary bridge. The temporary bridge will be constructed in an area sensitive to rockfalls and will allow traffic to be diverted from the Axenstrasse road thus facilitating further construction works. Construction of both the major tunnel construction lots is due to start in 2025. The construction site from Ingenbohl to Gumpisch stretches over a length of approx. 8 km. In the tunnel-driving phase, up to six tunnel drives (main and counter drives) are to be supervised in parallel. Also in the construction phase for the entire project, several construction sites for lining works are to be supervised in parallel.

In order to deal with the natural hazards posing a threat to the availability of the Axenstrasse road, an early warning system has been introduced and contributes to greater safety during construction works. Work on the Gumpisch temporary bridge is taking place whilst there is ongoing traffic on the Axenstrasse road. Thanks to the good cooperation with the road operator AfBN, the client and the security firm that are helping to control the adjacent traffic, the work and traffic have to date been accident-free.

Gas: The Baltic Pipe goes into operation


The Baltic Pipe has recently started transporting gas to markets in Denmark, Sweden and Poland, as well as to neighboring markets. ILF is proud to have contributed to the timely start of operation for this unusually complex construction project.

The interconnector between Poland and Denmark can transport gas in both directions, which not only opens up a new supply route for the transport of natural gas from the Norwegian sea, but also leads to a diversification of gas supply sources for many countries in the Baltic Sea region and in Central and Eastern Europe. Around 2.4 bn m3 of gas are expected to be transported by the Baltic Pipe per year over the next ten years.

ILF has supported the clients, Energienet and Ramboll, with numerous engineering services for the Jutland–Funen section. These included, among others, project management, Owner’s Engineering services, detailed design/construction design, tendering and construction supervision.

Connecting Siekierki CHP plant to a HV power transmission line


ILF and PGNiG Termika S.A. have signed a contract for the preparation of a feasibility study for the creation of an electrical connection between the Siekierki CHP plant and the Piaseczno–Mory transmission line in Poland.

The study shall investigate the feasibility of constructing a new 220 kV double-circuit line running from a new 220 kV switchyard to a cut in the 220 kV Piaseczno–Mory line, as well as a line to connect a new gas/steam unit to this switchyard. As part of the study, three different switchyard location options and several variants shall be presented. ILF will also give a recommendation on the optimal solution, taking all relevant planning, technological, social and environmental aspects into consideration.

“We always consider the impact on local residents and the environment in our work. We are focused on minimizing the impact on housing developments and valuable natural areas. In terms of planning for the timing and the amount of investment required in this project, we aim to make good use of existing infrastructure corridors from other transmission line facilities, and will consider different technological options – namely overhead lines and cable lines, as well as an option combining these two technologies.”
Rafal Blankiewicz, Managing Director of ILF Poland.

Reservoirs for Energy Storage


Providing efficient solutions for using existing snow-making infrastructure to additionally produce and store energy is also part of ILF’s portfolio – and exactly this is what has been done during one of our projects in the Kitzsteinhorn ski area (AUT).

The Gletscherbahnen Kaprun AG, with ILF’s help, has been relying on sustainable energy for years. In addition to the photovoltaic systems on operations buildings in the Kitzsteinhorn ski area, the Grubbach small-scale power plant also produces its own power from meltwater. The first construction stage of this combined pumped storage and hydroelectric power plant, with two turbines, was put into operation in 2012 – and a third turbine has recently been added to provide electricity in summer and snow in winter.
The special feature of this autonomous power production is that when the lever is moved in autumn, water is pumped through the pipes from the large high-altitude reservoirs “Mooserboden” and “Wasserfallboden” directly into the snow-making systems in the Kitzsteinhorn ski area. This means that no additional storage reservoirs need to be created for snowmaking in the high alpine part of the Kitzsteinhorn ski area.
In spring, on the other hand, the meltwater from a large catchment area is collected in the Langwied catch basin and continuously fed, via a 2-km-long pipeline and over 460 m in altitude, to the power plant. Here, three turbines convert 300 L of water per second into electricity, which generates 1.2 million kWh of green electricity in a regular year. This amount corresponds to the annual electricity consumption of approx. 350 households.

How does a pumped storage plant work?
A PSP temporarily stores surplus energy in the form of potential energy (elevation potential energy) in a reservoir. The water is pumped into the storage reservoir by electrically driven pumps so that it can later be used to drive the turbines and generate electricity. Surplus electrical energy from the power grid is taken during periods of low demand and fed back into the grid at peak load. Essentially, there is a lower and upper basin between which water is moved up and down – the lower basin can either be an artificial storage reservoir, a natural lake or a watercourse. In the simplest case, electricity is either generated by operating the pumps in reverse (turbine mode) or by using separate turbines, for which a wide variety of designs and sizes come into question depending on the operating conditions.

Uetliberg Tunnnel (CH): ILF helps Swissgrid turn up the voltage


Swissgrid has commissioned ILF, as part of the engineering consortium KiWa220 (@Suisseplan Bau, @Boess Gruppe), to plan and design the extension of the high-voltage line in the Zurich South area. In order to increase the security of electricity supply to the city of Zurich (CH) and the left side of Lake Zurich, the current line will be upgraded to 220 kilovolts (kV) and connected to the grid in the South.

In the first project section, the cable will be laid underground along the motorway. Subsequently, the cable will be pulled through the conduit blocks already in place in both tubes of the Uetliberg Tunnel. In the third project section, a new 2-km-long energy tunnel, with a diameter of approx. 4 m, will be driven using a tunnel boring machine.

The energy transition in Germany is gaining momentum


To transmit wind power from the windy North to the South, SuedLink, a high-voltage direct current (HVDC) transmission line consisting of multiple underground cables, is to be built in Germany.
The SuedLink is approx. 700 km long and will be implemented by the two project developers TransnetBW GmbH and TenneT TSO GmbH, with two 2 GW connections each starting in Schleswig-Holstein and running via Baden-Württemberg to Bavaria.

The project developer TransnetBW GmbH has submitted the first permit application documents for the southernmost permit application section, E3, to the Federal Network Agency. ILF, as the regional engineering office, has assisted with the preparation of these documents. The Federal Network Agency has already confirmed the completeness of the documents and the process of making the documents available for public review has been initiated.

What’s special about permit application section E3 is that this section of the transmission line runs through the Südwestdeutsche Salzwerke AG’s mines. The special structure in the mines will be connected via two new shafts, which will be almost 200 m deep. With the initiation of the final phase of the approval procedure, the foundations for an early start to construction of the SuedLink in the Heilbronn region have now been laid.

In the North, ILF, as the responsible regional engineering office, has also contributed to the permit application documents for permit application section A2 – the first northern section of the transmission line – being submitted to the Federal Network Agency in due time by the project developer TenneT TSO GmbH. The particular challenge in this section was to integrate the requested alignment for the two underground cables into the design documents for the special structure ElbX, an approx. 5-km-long tunnel structure between Schleswig-Holstein and Lower Saxony that runs under the River Elbe.

Microtunneling: Transit and retention collector in Warsaw (POL)


The Municipal Water and Sewerage Company commissioned ILF to prepare comprehensive design documentation for the final stage of the construction of the Vistula collector In Warsaw.

This largest transit and retention collector in Poland’s capital is expected to mitigate the negative effects of climate change on the city. Besides transporting wastewater, the new infrastructure facility will also temporarily store excess rainwater and therefore decrease the risk of flooding and reduce storm overflows into the Vistula river. The existing storm sewers as well as the sewer collectors to the Farysa facility and the pressure pipe from the Powiśle pumping station will be connected to the new collector. The collector, with a capacity of 50,000 m3 and base diameters from 1.2 m to 3.2 m, will be about 9.5 km long and will be constructed at a depth of 6 to 15 m below ground. For the construction of the collector, state-of-the-art trenchless microtunneling technology will be applied.

“ILF’s task is to prepare comprehensive design documentation for the third stage of construction of the Vistula collector – specifically, from the connection chamber with the Bielański collector to the Farysa facility, along with the pumping station and the necessary̨ associated infrastructure,” explains Marcin Przepiórka, Managing Director from ILF Poland.

The investment is part of a broader project co-financed by EU funds and implemented by the Municipal Water and Sewerage Company in Warsaw. Completion of the project documentation (construction design and detailed designs) is scheduled for late 2022.

EDCS: ILF develops concept for industrial energy supply system


As part of an energy research project, ILF has carried out a specific technical, economic and ecological evaluation of an innovative EDCSproof energy concept for Wiesbauer, an Austrian sausage producer. EDCSproof stands for “Energy Demand Control System – Process Optimization For industrial low-temperature systems” and is a collaborative research project led by the Austrian Institute of Technology (AIT), funded by the Austrian Research Promotion Agency (FFG) and involving eight scientific and industrial partners.

The primary goal is to develop an online control concept for industrial energy supply systems. This concept shall support the integration of renewables through the use of energy storage, create “flexible consumers” for electric grids, increase efficiency through optimal control of the overall system, and utilize waste heat by using high-temperature heat pumps (<150°C). Hence, it is a concept for decarbonization which recognizes the possibilities of digitalization.

The evaluation carried out by ILF included an investment calculation based on possible installation locations and the integration of the respective components in the power supply system taking into account the route of the existing piping, spatial conditions and other project parameters. ILF compared the EDCSproof energy concept with Wiesbauer’s existing energy concept (CO2 savings, reduction of primary energy factor, cost reduction, etc.) and detected an energy and production cost saving potential.

Gas: Reduction of emissions at compressor stations


Gas Connect Austria GmbH contracted ILF to carry out a feasibility study for the reduction of emissions at one of their compressor stations.

In the considered station, three gas compressor units, each with a mechanical shaft power of approx. 11 MW, are installed. Each compressor unit is driven by a gas turbine. For the feasibility study, two approaches were investigated and compared from both an economic and technical point of view. Furthermore, the time required for the implementation of each approach as well as the potential of each approach for reducing emissions were evaluated.

The scope of the reconstruction work and the amount of investment required for each of the two approaches differs.

One approach would entail replacement of one of the gas turbine driven compressor units with a larger electrically driven gas compressor unit, capable of covering the entire basic supply of the station. The remaining two gas compressor units would consequently only be used when needed, enabling CO2 emissions to be reduced by 95% and methane emissions to be reduced by 88%.

The other approach would not entail any major reconstruction works, but would still reduce emissions from the existing plant. Great potential for savings was discovered related to process vent gas. On the basis of these findings, ILF elaborated a solution for the reduction of emissions. When the gas compressor units are switched off, the natural gas remaining in the compressor lines is blown out into the atmosphere; therefore by re-compressing and re-feeding this process vent gas into the gas grid, methane emissions could be reduced by 80%.

Hydropower: ILF partner in Hydro4U


Hydro4U is an EU project funded under the Horizon 2020 research and innovation program. In this project, ILF and 12 other partners from eight countries are working together under the coordination of the Technical University of Munich to develop solutions which boost sustainable small-scale hydropower in Central Asia. Two pioneering hydropower types shall be implemented in demonstration plants in Kazakhstan and Uzbekistan.

To this day, small-scale hydropower remains largely unharnessed in Central Asia. Yet there is great potential to transfer European small-scale hydropower schemes to Central Asian regions. So far there are only few European reference projects in this region as they tend to be considerably more expensive than those of Asian competitors.

The Hydro4U project will now adjust two innovative technologies developed in Europe to the requirements in Central Asia. The aim of this project is keeping the costs as low as possible through concept simplification, modularization and standardization without compromising efficiency. At the same time, the project also focuses on key aspects such as sustainability, environmental compatibility and social acceptance.
In the course of the Hydro4U project two eco-friendly demo hydropower plants will be installed and assessed: one low-head plant with a capacity of up to 500 kW in Kazakhstan and one medium-head plant with a capacity of approx. 2 MW in Uzbekistan.

Project duration: 06/2021–05/2026

Countries involved: Austria, Belgium, Germany, Kyrgyzstan, Spain, Sri Lanka, Switzerland, Uzbekistan

ILF and GEV sign MOU for hydrogen project


ILF Consulting Engineers and Global Energy Ventures (GEV) have signed a Memorandum of Understanding (MOU) to identify and develop green hydrogen projects in Europe and Australia that include a compressed hydrogen (C-H2) generation and transportation solution, offering a valuable addition of marine transportation to the H2 value chain.

ILF will design the upstream infrastructure from the producer to the export or loading facility and the downstream infrastructure from the import or unloading facility to the consumer, while GEV will cover the port-to-port transportation of hydrogen using compressed gaseous hydrogen ships. For projects that involve importing hydrogen from regional markets in close proximity to Europe, such as the Middle East and North Africa region, GEV has identified an opportunity to leverage offshore loading capacity and develop a compressed gaseous hydrogen solution for the offshore wind industry. Thus, a fleet of vessels could provide an offshore loading and transport solution for areas where an subsea cable or pipeline on seabed is not suitable.

Jens Kottsieper, ILF Business Development Manager, commented, “The transportation of large volumes of gas is an issue that ILF has been involved with for over 50 years. We are pleased to be able to complement our pipeline expertise with GEV’s expertise in the cost-effective transport of hydrogen by ship. Working with GEV will allow us to provide our customers with even more comprehensive advice on their transportation issues in order to develop a solution that meets their specific needs.”

“Scaling up Green Hydrogen in Europe”


Date and time:
February 26, 2021
11:00 AM – 12:00 PM (CET) / 10:00 AM – 11:00 AM (GMT)

Green hydrogen is increasingly seen as an indispensable part of the Energy Transition. Ambitious targets for producing it have been set for the mid-2020s and 2030.

Many projects and use cases are proposed, but how is an industry that currently only operates at the level of tens of MW going to reach GW-scale quickly – and efficiently – enough? Will access to cheap energy at the boundaries of and/or outside Europe help to make green hydrogen competitive in the mid to long term, even taking the need to transport hydrogen into account?

ILF, Dentons  and Operis have produced a white paper on Scaling up Green Hydrogen in Europe. In it, we look across the hydrogen value chain and consider both the physical and contractual/regulatory infrastructure that will be needed to make the vision of a hydrogen economy a reality. We consider how to match supply and demand for hydrogen; suggest possible models for financing hydrogen projects and trading their output; and review the role of public financial support and other policy interventions. We are optimistic about the prospects, but also realistic about some of the challenges facing this new industry.

We will be launching the white paper at the online seminar.

After a brief presentation of our conclusions, a panel of industry experts who are engaged in commercial hydrogen projects will debate the issues and share insights from their own experience.

Speakers from ILF, Dentons and Operis will be joined by:

  • Julia Prescot, Chief Strategy Officer and Co-Founder at Meridiam Infrastructure, Member of the UK National Infrastructure Commission
  • Roland Schulze, Managerial Adviser on Low Carbon Technologies, European Investment Bank
  • Marinus Tabak, Plant Manager, RWE

Please click the “Register now” button below if you would like to attend the cost-free online seminar, or to receive a copy of the white paper when it is released.

We look forward to meeting you virtually and to an interesting discussion. Please do not hesitate to contact ILF if you have any questions.
