ILF embarks on new technologies to combat climate change


On November 30, 2017, Jens Kottsieper and Michel Kneller will be presenting a white paper on decentralized hydrogen production from renewable energy for the transport sector at the ÖGEW/DGMK Autumn Conference in Vienna, Austria.

In order to meet the climate objectives of the 2015 Paris Agreement to further reduce CO2 emissions, it will be necessary to increase the renewable energy share in the global energy mix. One potential solution would be to convert surplus renewable energy to hydrogen through a process of electrolysis, store it and make it available to the transport sector. Mr. Kottsieper and Mr. Kneller will also present key findings and lessons learned from the Demo4Grid project that is currently being implemented in Innsbruck, Austria.

You can have a look on the white paper here:
