Session 8

The recent presentation of the European Commission‘s „Green Deal“ and „The National Hydrogen Strategy“ by the German Federal Government will increasingly raise the interest in hydrogen in the next few years. This is comprehensible, given the versatile applicability of hydrogen for example as fuel for fuel cells, chemical energy storage for “regenerative” energy, reducing agent in steel production, or chemical platform for the synthesis of materials and molecules. The largest challenge is the production of “gray” hydrogen, which is currently to more than 90 % based on the CO₂-emitting steam reforming of fossil fuels. It is of utmost importance for the future to replace this by “green hydrogen”. Therefore, different sustainable processes of water electrolysis have to be developed and evaluated in a holistic manner. Within this session several photo- and electrocatalytic approaches will be discussed for their eligibility to provide “green hydrogen”.
