World’s first high-purity hydrogen from biogas.

Austrian researchers have demonstrated a chemical looping system can be retrofitted into biogas plants. It is said the new tech can produce high-purity hydrogen for fuel cells on an industrial scale. The scientists concerned said their system could produce hydrogen, on a decentralized basis, for €5/kg. Austria’s Graz University of Technology (TU Graz) and compatriot start-up Rouge H2 Engineering have announced the “world’s first” production of high-purity hydrogen from biogas, using a new chemical looping process.
