By day, the custom-built hydrogen fuelling station in Bolzano – for which Linde is the technology provider – is fairly quiet. In the evening, though, it springs into action as the fuel-cell buses return from their daytime travels with around 200 kilometres on the clock. Within just a few minutes, fresh gaseous hydrogen flows into the tanks: and they’re all ready to set off again the next morning. It’s that simple: but it wasn’t always.
The Linde Group provides turnkey solutions for gas compression and storage, with a focus on hydrogen refuelling stations
for all customer needs – whether for buses, cars, trains or any other application. The key component in the refuelling process is compression of the stored gas to a certain pressure for refuelling the vehicles: typically, from 350 bar for buses to 700 bar for cars. And for that, the H2
Mobility Solutions Team developed the ionic compressor: an invention that was to pave the way for hydrogen mobility.
