By that point, there will be enough used batteries removed EV’s that it will make sense to use them to store the excess energy rather than producing hydrogen. My Chevy Bolt came with 60KWH battery capacity. The warranty supports it to 60% of that capacity or 36KWH. The capacity of vehicle battery packs is continuing to grow, much faster than the ability to produce green hydrogen. Vehicles have very limited physical space for a battery pack compared to grid storage systems. Renewable generation facilities from residential rooftop solar systems to huge solar and wind farms will be able to incorporate all the used vehicle battery packs. Eventually all of electricity will be renewable either directly or from storage. When cells are no longer able to support grid storage, they can be recycled with the materials going into new vehicle battery packs.
