The SIQENS hydrogen refueling technology provides fuel cell grade green hydrogen from biogas or renewable methanol at the point-of-use. It can provide local green H2 from < 10 €/kg from 50 to 1,000 kg/day. This constitutes the fastest route to green hydrogen for vehicle fleets at 90 % lower electricity demand than electrolyzers.
The modular scalable system eliminates transportation of compressed hydrogen to the fuel station and provides commercial fuel cell vehicles with green hydrogen.
