Fuelling of Vehicles


The Fronius Solhub enables the refuelling of H2-powered vehicles as well as the storage and reconversion of solar hydrogen.

How it Works

By means of electrolysis, green hydrogen is produced from water and solar power. It can be stored and used for fuelling H2 vehicles. The hydrogen can also be stored seasonally and then transferred back to electricity and heat from the entailed fuel cell.
