We aren’t consuming batteries anywhere near the rate we consume oil and coal. Hydrogen even less than batteries.

So the amount of ships needed would still be a fraction of what we use now.

not now, but if hydrogen were to be used as an energy source/storage, then it'd be used plenty. same with batteries

We can make hydrogen everywhere, we can't 'make oil'.

[–] [email protected] 4 points 1 week ago (1 children)

We absolutely can 'make oil'. Been doing it since world war II. Synthetic oil is extremely common.

I mean, yeah, but also, that's not really efficient or effective for burning.

[–] [email protected] 1 points 1 week ago (1 children)

Neither is hydrogen.

I'm not disagreeing, but if the energy is surplus, might as well make hydrogen, at least we don't end up with pollution.

arguably, compressing natural gas into LNG is fucking stupid, but apparently the market rates work out, so it's economically viable. And here we are compressing a gas into a liquid just to ship it over the ocean lol.

market economies are just funny.

Oh certainly. Power storage is a real problem, especially with up-down renewables. I just didn't understand why you were saying oil can't be produced but hydrogen can. Synthesizing oil for power storage is a terrible idea 😄

Same for hydrogen really. The only case where it really matters is flight, which requires energy densities that will only ever be achieved by hydrocarbons or maybe hydrogen.
