Frankly, if you want to insist using hydrogen, the best thing to do with it would be to react it with CO2 to make synthetic gasoline and use it in the internal-combustion engines and gas stations we already have. permalink fedilink source parent hideshow 2 child comments replies: [–] TropicalDingdong@lemmy.world 1 point 2 years ago (1 child) I think you store it in salt. permalink fedilink source parent hideshow 2 child comments replies: [–] grue@lemmy.world 2 points 2 years ago Not in a car, you don't.
