Well it doesn't in some ways, but I think many overlook the fact there is going to be trillions (quadrillions?) of kWhs of free/negative price electricity in the coming decades - when there is too much solar and/or wind on the grids. There needs to be more productive uses of this free electricity and I imagine H2 is one of them. NB: Batteries won't solve this unless prices dropped astronomically. The issue isn't overcapacity on a day by day basis, it's seasonal overcapacity. Areas further south are less affected by this, as there is less seasonal variation in solar output. You're not going to charge a battery then discharge it weeks later - the economics don't make sense.
