- pfdietz 4y agoUltimately the rare high price peaks can be shaved with green hydrogen instead of natural gas. Hydrogen can be stored underground, with a cost per unit of energy storage capacity of about $1/kWh, some two orders of magnitude cheaper than batteries. Round trip efficiency sucks, but that's not important for rarely used storage.
