For Fraunhofer-Gesellschaft it is crucial to lay the foundation for a CO2-neutral hydrogen economy today and to optimally prepare the local economy for the coming hydrogen era. Achieving the climate targets with greenhouse gas neutrality of all energy sectors will only succeed through targeted sector coupling. By using green hydrogen - i.e. hydrogen produced from renewable energy sources - it will be possible to reduce CO2 emissions in areas where energy efficiency measures are insufficient and where direct electricity use is not technically or economically feasible or practical. Electrolysis is a central process and hydrogen the link between the electrical and the material world. Fraunhofer is a central strategic partner of politics and industry in the implementation of hydrogen technologies in practice. We offer our customers solutions and product developments along the entire process chain from material, technology and system developments for generation, storage and conversion to system integration of hydrogen and downstream products.
