The production, transport and end-use of green hydrogen and the derived electro-fuels will be key technologies in the future energy system. These green molecules are very dense energy carriers, which makes them suitable for the import and the storage of renewable energy. At BRITE, we work on the safety aspects of the hydrogen and e-fuels value chains, as well as on the efficient and flexible end-use of these fuels for the production of heat and power. We developed advanced simulation tools and test equipment to maximize the efficiency of hydrogen- and e-fuels-based systems and to minimize their impacts on the environment.
