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.

      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?

        Hydrogen reaction to oxygen in a fuel cell turns it back into water

          So no water is lost?

            Yes, basically. Enegy is used on H2O gets split and turned into H2 and O2, the H2 then in the fuel cell gets to react again with O2 to produce energy, less than what was used to split it, why it is inefficient, and now stable H20

            That’s right!

            Two H2 molecules (hydrogen) react with one O2 molecule (oxygen) to become two H2O molecules (water)
