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.
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)
once you burn it
