What is Hydrogen Refuelling?

Refuelling takes about as long as filling a petrol car. Hydrogen stations are still rare in most countries. Prices are given per kilogram of hydrogen. Hydrogen tanks are tested to withstand crashes and very high pressures.

How it works

A dispenser pushes cooled hydrogen into high-pressure carbon-fibre tanks through a sealed nozzle.

Why it matters for your car

Station networks are limited; plan trips carefully. Follow the station’s instructions; the nozzle locks to the car.
