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.

    Don’t store it in diatomic form. Ammonia is the common alternative for hydrogen storage and transport, iirc

    And even if round trip efficiency is poor, if renewables are in excess, it would be so much better to dump that energy into something that to have to curtail.
