To save you all a google: it's made from natural gas, at a pretty significant energy loss compared to just burning the gas. It generates about 4 times more co2 than burning diesel.
Didn‘t we have a process to electrically synthesize hydrogen out of water?
Electrolysis, it works but it takes a lot of energy to produce, so burning hydrogen from this would be a fools errand.
But you could technically build huge solar panel areas in deserts and bring that hydrogen to populated areas. Or you could use excess energy from renewables to produce hydrogen, storing at least some of the excess energy for times where renewables produce less.
