Hydrogen fuel cell vehicles are clean and efficient, producing no tailpipe emissions other than water vapour.
Hydrogen technology offers the following key benefits:
- The fuel cell vehicles only emit water vapour, completely cutting out CO2 and other harmful emissions from the exhaust
- They'll be quieter than diesel buses
- They'll be more comfortable for passengers as acceleration is smooth and progressive, thanks to the electric motor
Taking into account the methods of hydrogen production, it is expected that overall the fuel cell vehicles will produce 50 per cent less CO2 than a diesel vehicle.
Costs versus benefits
Although hydrogen-powered vehicles are costly, we are kick-starting commercial use of these vehicles and raising awareness of their environmental advantages.
As demand increases, we expect costs to decline and hydrogen technology to become a more affordable and viable alternative.
