Austrian solar energy company Fronius has completed a two-week test operation with a bus fuelled with green hydrogen at Wels in Upper Austria. The clean hydrogen gas is produced from solar power at Fronius’ SolHub facility at the SAN Biotech Park, in Herzogenburg, Lower Austria.
During the trial, the emission-free Solaris Urbino 12 Hydrogen bus was refuelled daily with around 13 kilograms of hydrogen. Refuelling took around 15 minutes which depending on operating conditions, provided a range of “at least 160 kilometres”.
“The best thing is that heat and water vapour are the only products of the chemical reaction in the fuel cell, they act as a kind of mini power station,” explains Abba Mejer, head of Solaris Bus. “Refuelling with hydrogen is short, convenient and hardly different from refuelling a diesel vehicle.”
Martin Hackl, Head of the Solar Division at Fronius says, “With the Solhub, we offer a complete turnkey solution that makes it possible to produce local, green hydrogen and use it to refuel fuel cell vehicles.”
Fronius’s aim with the trial was to prove the practical feasibility of locally produced green hydrogen. “We are showing that the technology works and is suitable for everyday use,” says Thomas Rührlinger, who develops new business models at Fronius.
“Sustainable and locally produced hydrogen holds great potential and strengthens domestic value creation as well as regional business models,” he adds. “In the next few years, we expect to see a large number of additional implementations with customers from commercial and production companies, municipalities and transport companies, as well as logistics, tourism, operators of special vehicles and in the context of renewable energy communities.”
