To be suitable to be used as a fuel, the hydrogen gas (H2) is compressed at about 350-700 bars pressure via advanced mechanism on site and is then distributed via a dispenser similar to the ones used in petrol stations. Hydrogen fuel dispensing systems are safe and user-friendly and have international standards to ensure compatibility between all refuelling stations and vehicles.
Currently, hydrogen is often delivered to the fuelling location in the same way as it is distributed to industry: in pressurised tanks on lorries. However, at suitable sites hydrogen can be produced on-site by electrolysis, in the best case with the aid of renewable electricity obtained via direct coupling (wind/solar), or through grid-balancing services.Filling the tank of an automobile, bus or a truck takes as much as it takes for classic gasoline or diesel vehicles..
