Barry Posted January 7, 2018 Report Share Posted January 7, 2018 No full details yet but it looks like Hyundai are set to release a hydrogen powered SUV Anyone got any thoughts as to why hydrogen hasn’t really taken off as a fuel yet? https://www.autocar.co.uk/car-news/new-cars/hyundai-reveals-2018-hydrogen-fuel-cell-powered-suv-ahead-ces-debut 1 Link to comment Share on other sites More sharing options...
treks Posted January 8, 2018 Report Share Posted January 8, 2018 Hydrogen is very difficult to store. Hydrogen molecules are so small that they escape through the material used for "normal" fuel tanks, and while effective storage tanks do exist for use in vehicles, they are very heavy and take up a lot of space in a normal vehicle. The alternative is to use fuel cells in a vehicle to generate hydrogen on demand, but on this scale, the technology is expensive in terms of the energy required to make a given volume of hydrogen gas. For the moment, electric cars are cheaper than hydrogen-powered cars to produce, and is likely to remain cheaper until the issues of bulk storage and distribution of hydrogen are resolved. 1 Link to comment Share on other sites More sharing options...
