Green electricity storage facility in Gaildorf

more

The water battery is an innovative combination of a wind power plant and a small and flexible pumped storage plant for the storage and controlled feed of volatile renewable energy into the grid. The first pilot project is currently underway in Gaildorf (Germany). For this purpose, ILF Consulting Engineers was commissioned by Max Bögl Wind AG to provide different consulting and design services for the pumped storage plant.

Innovative solutions and various other unique features characterize the initial implementation in Gaildorf and make this project a lighthouse project. The storage plant has a head of 200 m. With regard to machinery, the innovate character is emphasized by the 3×6 MW variable speed reversible pump turbines with asynchronous generator and full converter, all of which is meant to achieve maximum flexibility for demand based storage and feed-in of the generated energy.

The forward-looking project is supported with EUR 7.15 million funded through the environmental innovation program of the German Federal Ministry for the Environment, Nature Conservation, Construction and Nuclear Safety.*

Take the train, collect Green Points, protect the environment

more

Once again, ILF Consulting Engineers’ employees in Austria are among the most frequent train passengers in Austria. By taking the train for business trips, last year ILF employees collected lots of “Green Points”, a program initiated by the Austrian Federal Railways (ÖBB), and reduced CO2 emissions by 86.8 tons. ILF is proud that this figure again represents a significant increase from the previous year (63.1 tons).

ILF greatly appreciates this ÖBB initiative, as the sustainable protection of the environment is extremely important both with regard to the structures and facilities planned by ILF and the daily project work. We continue to strive to contribute to sustainability in Austria by taking ÖBB trains for business trips and thereby supporting this great initiative.

Resilient infrastructure – how does that work?

more

Extreme heat or snowfall, storms, floods and forest fires can have multiple impacts on our daily lives. These phenomena are not new but they are increasing in intensity and frequency, and are therefore a great challenge for the resilience of transport infrastructure. The consequences that we all notice are extensive traffic jams, lengthy closures, material damage, major detours and long delays.

ILF Consulting Engineers is currently working intensively on two research projects in Germany, to be able to counteract the effects of ongoing climate change. The resilience of transport infrastructure has to do with the availability of the transport network in the event of effects resulting from extreme events of any kind.

The great complexity of the topic and the interconnection of different aspects require a high level of technical competence. Just as important is the ability to recognize functional relationships and to structure them appropriately.

The competence and experience of ILF’s experts makes it possible to implement challenging projects at home and abroad in the best possible way.

Electro-mechanical challenge at the Engelberg Base Tunnel

more

ILF Consulting Engineers has recently won several very interesting projects in the field of electro-mechanical equipment for road tunnels. One project, which deserves special mention, is a construction supervision contract at the Engelberg Base Tunnel near Leonberg, which was awarded to ILF and a partner by the regional government authority serving the German city of Stuttgart (Regierungspräsidium Stuttgart).

Due to its central location, linking the A8 and the A81 motorway, the twin-tube tunnel with a length of approximately 2,530 m plays a key role as a north-south and east-west traffic hub in southern Germany.

In addition to highly complex structural rehabilitation works being required due to deformations and damage of the permanent lining in parts of the tunnel, the electro-mechanical equipment will have to be upgraded to meet the latest safety requirements.

Modeling of water resources

more

#innovatethefuture

Water is life and a resilient infrastructure is a key element for sustainable development and political stability. For the planning, design and implementation of many infrastructure projects and for a comprehensive river basin management, knowledge about the availability of water over space and time is an important pre-requisite for decision-making and design processes.

Water balance analyses depend strongly on suitable software and, above all, on reliable data on temperature, precipitation and discharge, etc. In many regions of the world, the quality and quantity of this data from the past is not sufficient – a dilemma when it comes to making informed investment and planning decisions.

This is why, a modeling tool called SUPRA tool (Simulation of Water Resources Under Present and Future Climate) is currently being developed and tested in close cooperation with the long-term research and development partners alpS GmbH and alpS Research of the University of Innsbruck. In the future, this tool will make it possible to calculate the current water balance situation and future scenarios more accurately, especially in mountainous regions with limited data availability but also in all other areas around the world.

ILF is member of the Bavarian Hydrogen Alliance

more

Hydrogen is regarded as one of the key elements for global energy system transformation and climate protection, as it can be produced and used flexibly and without emissions, and at the same time is easy to transport and store.

To strengthen and further develop Bavaria’s technological competence in the field of innovative hydrogen technologies, the State of Bavaria founded the Center Hydrogen.Bavaria (H2.B) in 2019 and initiated the Hydrogen Alliance Bavaria. The aim is to bring together key players in industry, science, and politics in order, among other things, to advance the topic of “hydrogen economy” in Bavaria as quickly as possible and to achieve the use of hydrogen in broad practical application. The focus here is, above all, on demonstration and lighthouse projects.

ILF has many years of practical experience in consulting, planning, and project management in the energy and transport sector. We are currently supporting several pilot projects on hydrogen production, transport, and acceptance. Also, ILF advises companies on the use of hydrogen along the entire value chain, thus contributing to the establishment of a hydrogen infrastructure.

We are therefore delighted to be able to contribute to the progress of hydrogen technologies as an official member of the Bavarian Hydrogen Alliance since June 2020.

Kick-off for further design services for the Belchen Road Tunnel

more

The Belchen road tunnel was opened in 1970 and consists of two separate twin-lane tubes with unidirectional traffic, each having a length of 3.2 km. In early 2021, with the so-called rehabilitation tunnel going into operation, the Belchen tunnel system will comprise three twin-lane tunnels. ILF Consulting Engineers is also involved in the design and construction of the rehabilitation tunnel.

Extensive rehabilitation works were already carried out on the existing road tunnel from 2001 to 2003. However, the swelling rock (anhydrite) is increasingly leaving visible traces. In order to ensure the safety and capacity of one of Switzerland’s busiest roads, the two existing tunnels at Belchen will be refurbished one after the other as part of the second rehabilitation.

The intended measures include the replacement of parts of the in-situ lining, backfilling of cavities that were detected in the crown, design of utility lines and fire-fighting system, and expansion/new construction of cross passages. Water ingress in connection with swelling anhydrite are the great challenges in these complex ground conditions.

Being part of the design consortium, ILF was tasked with developing and implementing the project up to commissioning by the Swiss Federal Roads Office (FEDRO). The project was launched in June 2020 and is expected to be concluded by mid-2032.

Ferngas receives the building permit for its gas pipeline

more

According to the Federal Ministry of Economics, natural gas, having a market share of around 44%, is the most important source of heat and energy for private households in Germany. To continue to meet the associated high demand for natural gas, the network operator Ferngas, which operates a transmission and distribution network in Bavaria, Thuringia and parts of Hesse, Saxony and Saxony-Anhalt, is renewing one of its existing natural gas pipelines in Saxony and Thuringia.

The 125 km long pipeline, which runs through Saxony and Eastern Thuringia, was built in the 1950s and 60s and is to be completely renewed by 2023. The modernization is planned to take place in several sections, without any disruption being caused to the supply of gas along the existing pipeline route. In addition to the main lines and connecting lines, numerous ancillary facilities and route-related infrastructure are being renewed. The new pipeline will largely remain in the existing pipeline route, which will minimize the impact on both the environment and local residents.

The aim is to increase the operational flexibility of the network, as well as the capacity and the security of supply for the coming decades. Furthermore, the renewal of the pipeline will help improvements to be made to pipeline monitoring and control.

ILF Consulting Engineers has been commissioned by Ferngas to provide project control and project management services in accordance with the scope of services listed in the AHO (Committee of the Associations and Chambers of Engineers and Architects for the Fee Structure) booklet no. 9.

Having nearly completed the renewal of the pipeline in Saxony, the statutory authority approval and thus the building permit has now been received for the Thuringian section of the pipeline, enabling Ferngas to reach another decisive milestone in the renewal of its gas pipeline in Thuringia.
