Comment on GM’s hydrogen ‘power cubes’ will be used in cement mixers and terminal tractors
CrimeDad@lemmy.crimedad.work 6 months agoYeah that’s a problem. However, it might make more sense on balance if we have big nuclear power plants generating clean ammonia while off peak electric demand.

Why not clean hydrogen? Just the handling issues?

Ammonia is wayyyyyyyy easier to store and contains more hydrogen. Pity about the environmental and health dangers

You don’t have to store liquid ammonia under high pressure and it has a higher energy density by volume than hydrogen. Also, ammonia is already very useful beyond energy storage, such as for fertilizer. Maybe a hybrid system is the way to go, with hydrogen for smaller consumer applications and ammonia for larger industrial ones. I don’t know if there’s good way to produce ammonia directly by electrolysis yet, so the ammonia might still have to be derived from hydrogen anyway.
