Fronius Turns Rooftop Solar Into Green Hydrogen

Fronius has supplied SAN Group with an electrolyser to produce green hydrogen at its company headquarters in Austria, using electricity generated by a rooftop solar installation.

Fronius’ Solhub installation will used electricity from the 1.5MW PV installation to produce around 100 kg of green hydrogen a day for SAN Group’s fleet.

The amount is enough to fill around 16 passenger cars or drive more than 1500 km in a bus or truck.

Fronius solar energy global director Martin Hackl said: “The installation of the first Fronius Solhub is a flagship project.

“Green hydrogen is generated and stored directly on site using solar energy and water. This is then used to fill hydrogen vehicles and, thanks to reconversion, the solar energy is also available in the winter—in this way we can make use of the sun 24 hours a day.”

The ground breaking ceremony took place in May 2021 and the Fronius Solhub will be commissioned in spring 2022.

“The idea behind the system is to store and use solar energy 24 hours a day. In the future, the fully integrated energy concept with waste heat usage and reconversion of the excess hydrogen will supply the entire SAN Group site,” said Martin Blauensteiner, managing director of SAN Real.
