From Slurry to High-Purity Hydrogen

Pushes the development of technologies for the production of green hydrogen: Viktor Hacker from the Institute of Chemical Engineering and Environmental Technology at TU Graz. Frankl - TU Graz By Susanne Filzwieser - Hydrogen from real biogas: TU Graz and the start-up Rouge H2 Engineering have scored a world's first in producing high-purity hydrogen from biogas directly at a biogas plant using a new chemical looping process. Green hydrogen is seen as a beacon of hope in the energy and mobility revolution, but it is not yet suitable for mass production. There are several reasons for this. Hydrogen is currently produced mainly centrally from fossil raw materials. It then has to be compressed or liquefied in an expensive and energy-intensive process in order to be delivered to filling stations, for example. Expensive infrastructure with high investment costs is needed there to store large quantities of hydrogen.
