@ulintl has linked an article to which energy storage is good for farmers who have solar panels on their barns etc. where salt batteries were also discussed. the only manufacturer in europe i found was an austrian company iirc.
would sure be interesting if there is a low tech way to build them. the austrian one was rocket science full of special materials etc.

> Usually you don’t want a highly explosive and pressurized gas being mobile

well, here in germany there are cars which use natural gas/LPG. the only restriction is that you can't park them in underground garages.

the nice thing with hydrogen is that you might either use it for combustion or with fuel cells. only toyota bothered using fuel cells so far (afaik). safety doesn't seem to be the problem: https://en.wikipedia.org/wiki/Toyota_Mirai#Safety . it still has a battery, but that's 1.6 kWh instead of teslas 100 kWh.

i can see that the density isn't ideal which makes the processing into methane etc. interesting. i can't find the paper on that now, but i swear the stuff i read about wasn't very complicated.

the problem with things like pumped storage is that they need the right geology for that. e.g. in northern germany there aren't that many places which are hilly and not populated.

my point is: _if_ we put wind and solar everywhere it's dumb to turn of those things because there is "too much power" (which happens frequently). would make more sense to just run electrolysis with it, maybe convert that H2 into methane or whatever. i don't see that big batteries are a good solution for this, even if all the car manufacturers want us to believe that using old car batteries for storage is a great solution ;)

not poer storage: what makes H2 interesting too is that it can be used for other things like haber-bosch.

you can even make methane out of H2 in a bioreactor. i left that out ;)

it just smells funny that for decades H2 was written off as too problematic etc. and not we get batteries shoved down our throats. where 9/10 are wasted storage and problematic waste. H2, while more complicated, requires "something to pressurize gas in".

maybe someone can enlighten me:

why is/was hydrogen as energy storage torpedoed for decades now (that it is too late)? it's clean after burning it, can be produced from either electrolysis or natural gas. storage is a bit complicated, but manageable. why should this be worse than batteries?

i've read so many shitty reasons why H2 is "bad":

- "converting natural gas isn't green": yes no shit, but it helps to fill the gap. should've started earlier.

- "not enough power to do electrolysis": every other energy storage solution seems worse at large scales, especially batteries.

- "not enough platinum to use as catalyst for fuel-cells": i bet you can throw enough research on it and find another catalyst. hell, _we_ are full of catalysts that don't contain platinum.

twitter doing twitter things..

> *Censorship* is harmful. This is an attack on my free speech.

twitter is a private business, not speakers corner. talking about twitter like it is some kind of commons is just cementing it as something more than a website full of bad takes and groupthink.

your free speech is your own instance! :)

@Elfie i once had the "pleasure" to deal with someone who was manic. it looks like this.
