Right, but then we're not talking about combined-cycle gas turbines to convert hydrogen back into electricity. If we're going to boil water than that's much less efficient than the ~66% efficiency we get out of combined cycle gas turbines.
Also, in case you weren't aware a combined cycle turbine also involves boiling water and spinning a turbine. The reason why they're so efficient is because energy is extracted both from the gas turbine (basically a jet engine) and a steam turbine driven by the heat from the exhaust from the gas turbine.
>Honestly, you should learn some thermodynamics and chemistry before accusing others of being ignorant.

Hydrogen embrittlement is a real thing, don't just go hand-waving it away: https://www.energy.gov/sites/prod/files/2014/03/f12/hpwgw_em...
What about thermodynamics am I missing?
