It’s still not earning you money to spend electricity because you still have to pay the transfer fee which is around 6 cents / kWh but it’s pretty damn cheap nevertheless, mostly because of the excess in wind energy.
Last winter because of a mistake it dropped down to negative 50 cents / kWh for few hours, averaging negative 20 cents for the entire day. People were literally earning money by spending electricity. Some were running electric heaters outside in the middle of the winter.
You just sent me down a rabbit hole, I had heard of electrolysis but didn’t realize that it was able to store energy on a large scale. Seems like a waste of water though.
Well the water isn’t disappearing anywhere and I believe that works on salt water as well
it works on salt water, submarines do it for oxygen, obviously, though you also have to deal with the salt build up, along with mineral build up, though unlike desalination, you can just run constant water flow through and yoink a small portion of it, you don’t have to yeet all the water. So that makes it easier.
How is it not disappearing if it’s turned into hydrogen?
once you burn it
