Both the Hyundai and the Toyota use hydrogen to power the fuel cell, which turns the energy into electricity via a chemical reaction and powers an electric motor to propel the vehicle.Ī hydrogen internal combustion engine can be produced by simply making a set of modifications to existing petrol and diesel engines. At this time, the only FCEVs in production are the Hyundai Nexo crossover and the Toyota Mirai, with Honda recently having pulled the plug on the Clarity FCEV. However, despite several attempts, no carmaker has been able to push FCEVs into the mainstream spotlight, and as such, they continue to be a rarity. Yes, the world has seen a variety of hydrogen-based fuel-cell electric vehicles (FCEV) – both in concept and production forms – over the last few decades. Haven’t hydrogen-powered vehicles been around for years? However, not every player wants to head down that route, and some prominent names are evaluating other forms of power sources for future vehicles, including using hydrogen as a fuel in an ICE vehicle. Most automakers have already climbed aboard the promising electric mobility vessel, and are working to transition from internal combustion engine (ICE) vehicles to ones powered by lithium-ion batteries. In a world faced with more uncertainty than ever, the only well-documented certainty is that fossil fuels will soon be ditched in favour of alternative energy sources for mobility applications worldwide.
