Hydrogen is dispensed from a pump in the form of a gas. This means you can "fill up" in just a few minutes by connecting a nozzle to your vehicle's tank, just like a combustion engine vehicle.
However, because the hydrogen is in its gaseous state, the process used to convey it to the pump differs from that used at a petrol service station.
The hydrogen passes through various modules at the station before arriving at the dispenser: it is compressed for storage then cooled ready to be dispensed when a vehicle arrives at the pump. To find out how a hydrogen station works, click here.
