The hydrogen fuel cell electric vehicle (FCEV), which simply runs on pressurised hydrogen from a fuelling station, produces zero carbon emissions from its exhaust. The Canadian Hydrogen and Fuel Cell Association recently produced a report extolling hydrogen vehicles. China, with electric vehicle sales of more than one million a year, is demonstrating how these issues can be addressed. Not only is this an answer to the “range anxiety” of prospective electric car owners, it also addresses their high cost. Batteries make up about 25% of the average sale price of electric vehicles, which is still some way higher than petrol or diesel equivalents.
