And, as in Utah, they seem to be planning to burn the hydrogen mixed into CH4 to drive turbines. The storage appears to be pumping H2 into existing CH4 wells, although it is hard to tell. I am anyway still not seeing any big H2 fuel cell projects, never mind solar/wind -> H2 -> fuel cell.
What you're doing is just concern trolling, and suggesting that just because a program won't instantly get to zero emissions it is somehow not real. Meanwhile, electric cars are still being charged up mostly by fossil fuels, a fact that cannot change on the large scale without green hydrogen. Somehow, this fact is never brought up in every anti-hydrogen attack.
A gas turbine can get you up to 60% efficiency BTW. While fuel cells are arguably the better idea in the long run, it is not a huge problem to use gas turbines for now.
Instead, there are legitimate comparisons of hydrogen and other possible storage media. Harassing people for discussing such comparisons, and posting dubious assertions about hydrogen's maturity as a storage medium, does hydrogen and you no favors.
