“Solar PV + storage” is likely to be utility-scale storage sized at ~4h of the facility’s peak production; this lets the plant shift the load from the middle of the day when the sun is strongest to the evening where the residential power demand peaks. There is an interesting report on this: https://emp.lbl.gov/utility-scale-solar/ https://emp.lbl.gov/utility-scale-solar/ It seems to me that the affordability of short-term storage is a really under-reported story. It seems to be adding $10-20 $/MWh which is not trivial but still leaves solar competitive with other sources (except perhaps gas). It’s not clear to me that there is an obvious candidate for seasonal storage though. Anyone seen a good analysis on that? Green hydrogen is one possibility but the OpEx seems high, if you have a hydrogen plant you want to run it all the time to amortize the cost right?
