Batteries on a large scale fall behind H2 storage if you have big enough tanks, and if you correctly factor in the costs of batteries and tanks. Where the lines cross is an open question.
I live 10 miles from a big gas depot in Selma NC. They hold lot and are very simple, big inverted buckets that rise and fall with the gas. You can electrolyze H2 into a tank and you get compression for free. Battery manufacturing, care and feeding is non-trivial. H2 is worth a look for grid size storage. Pump storage is similar in efficiency, but hell on the environment, destroying important watersheds, drowning arable land and habitat. Big dams cost a lot. Turbines. Makes a tank of gas attractive.
