The thing that gets overlooked too often is biomass. This graph shows very nicely that there is quite a considerable amount of biomass that accrues over the year (sewage, forestry waste, agricultural waste,…).
If you look at how much *long term* energy storage is needed in a grid based on 100% solar and wind (with 1-2 day battery backup) then biomass could cover all of that. No hydrogen or other expensive boondoggles needed.
