It'd be great in a renewables-based grid for energy storage and transport. It could be carefully controlled and monitored because of the partial centralization.

It'd be great in a renewables-based grid for energy storage and transport. It could be carefully controlled and monitored because of the partial centralization. I'm not sure it'll ever make much sense for vehicles unless you could increase the density so it's stored as a slush without needing a high-pressure or an ultra low-temp holding tank.
- bobthepanda 4y agoRight now, for planes and ships, it’s either hydrogen or syngas, because batteries are too heavy.

- dahfizz 4y agoYou can't just put hydrogen in a tank like you can with i.e. propane. It's a real pain to deal with, and I don't think grid scale hydrogen will ever work out. It would make more sense to use the hydrogen to synthesize methane, and then use that for grid scale storage and generation. This would be carbon neutral.
- gadflyinyoureye 4y agoThese are the types of conversations we need. So many people crap on hydrogen, but you can use it in a variety of ways. We can run cars on methane or convert it to ethanol. This makes converting our current fleet of vehicles cheaper and more realistic than converting to an all EV future. Even if we really, really wanted to move to EV, we can convert the existing fleet to carbon neutral ethanol for the next 50 years while slowly introducing EVs.
