Vehicles running on hydrogen technology benefit from a long range on a single refuelling. Various technologies are being developed that aim to deliver costs low enough, and quantities great enough, to compete with hydrogen production using natural gas. It can be produced by electrolysis of water, or by thermochemical or pyrolytic means using renewable feedstocks, but the processes are currently expensive. Īs of 2019, 98% of hydrogen is produced by steam methane reforming, which emits carbon dioxide. Hydrogen aircraft are not expected to carry many passengers long haul before the 2030s at the earliest. Īs of 2021, there are two models of hydrogen cars publicly available in select markets: the Toyota Mirai (2014–), which is the world's first mass-produced dedicated fuel cell electric vehicle (FCEV), and the Hyundai Nexo (2018–). Power is generated by converting the chemical energy of hydrogen to mechanical energy, either by reacting hydrogen with oxygen in a fuel cell to power electric motors or, less commonly, by burning hydrogen in an internal combustion engine. Hydrogen vehicles include hydrogen-fueled space rockets, as well as ships and aircraft. Vehicle that uses hydrogen fuel for motive powerĪ hydrogen vehicle is a vehicle that uses hydrogen fuel for motive power.
