If you want to follow this article you are a better man than me but apparently it is the future.
Currently 95% of hydrogen is produced from fossil fuels. This is OK if you are using it to make fertilizer and other products. Its use as a fuel for transport is a completely pointless exercise from the environment angle until such time as they can get the power from renewable sources.
The people in this article are working on that and the possibility seems good. You might ask why use electricity (from any source) to make hydrogen vehicles when you can cut out a step and just use electricity. The point is hydrogen solves the two stumbling blocks with electric cars. It can be carried in comparatively light weight fuel tanks of any size. Tanks don't deteriorate or have a use by life. The tanks can be filled at about the same speed as a petrol refill instead of hours for electric.
Like all flammable compressed gas it has its dangers but no worse than the LPG we have had for years and certainly no worse than the very high pressure required for Liquid Natural Gas.
Might be a better way to go than straight electric.
