There is already free energy. In 2024, California curtailed 3400 GWh of solar. Hydrogen is one of the easier ways to load shift that to winter or processes which need something denser than batteries. I actually prefer synthetic methane (worse efficiency) because it is more immediately usable.
Looking at the charts[0], load shifting all the way to winter seems unnecessary. You only need to load shift until ~6pm, in which case there are plenty of better options out there like grid-scale batteries, flywheels, pumped storage hydro, etc.
