Nevertheless, hydrogen still has niches where its main strengths – lightness and quick refuelling – give it a clear advantage. While you can fit your personal driving lifestyle around strategic battery charging stops, this is not ideal for a commercial vehicle that needs to run for very long periods and distances with only short waits to refuel. The weight of batteries for eight hours of continual usage would also be prohibitive in a train, for example. So, for industrial vehicles, hydrogen seems like a viable option, despite the inefficiency. Nevertheless, in the UK, there were only ten hydrogen-powered buses in service in March 2019, alongside 155 electric ones (with more arriving) and 3,669 hybrid ones. But a hydrogen double-decker is also coming into service in London, with hydrogen diggers and trains also already in use. Stock market darling Nikola Motor is working on hydrogen semi-trailer trucks alongside electric and hybrid variants.

But for personal car users, it’s no contest. Hydrogen evangelists are still arguing that FCVs are the future of personal transport and the technology will take off in 2020. It’s likely that FCV energy supply-chain efficiency will be improved over time and more renewable energy sources used in hydrogen production. However, considering the number of BEVs already on the road, FCVs have lost this battle already and will never catch up. A BEV is a viable form of personal transportation right now in most developed Western nations. There are lots of options with over 200 miles of range, and Tesla TSLA has even hit 400 miles. There are charging points springing up all the time, with more than twice as many EV charging points in the UK as petrol stations. The battle for the future of green personal transportation is over, and battery electric vehicles have already won.
