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’.

you really think this is going to stop the globalism aspect from happening? If you can ship something, and get better market rates on it, you’re going to do it. Economics follows the cheapest route, not the most efficient.

It also just makes sense if you think about it. Places like alaska are going to struggle to generate green energy compared to another place like, texas for example. If you can ship in green hydrogen much cheaper than you can locally produce energy, why wouldn’t you? It’s a reasonable solution to the problem of supply and demand scaling.

Yeah, there’s no reason to be transporting hydrogen long distances. You can make it anywhere that has water and electricity. And if you’ve transitioned to a hydrogen based economy (which is a big if), ships wouldn’t run on oil any more anyway, so there’s no problem there.

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

no we can’t make hydrogen everywhere, there will be regions with large excess of renewable energy compared to population. these places could export hydrogen. you also don’t need a lot of transport if crude is extracted near place where it’s used, like for example heavy crude from alberta

That implies that we can make electricity everywhere, which is technically true but not really the case because there’s countries with more and with less free space, with more suitable places and less suitable places to put renewables.

Those ammonia tankers will happen. At that point btw we’re not just talking about electricity, but also chemical feedstock.

While true, it’s very unlikely we’ll use hydrogen. It’s very impractical for this use compared to alternatives

If you have water you have hydrogen.

there’s no reason to transport hydrogen if they build infrastructure to use it as a fuel they will build a process to make it on site
