It’s probably very low efficiency, but if you can design renewable energy systems to provide enough overage during peak generation periods, maybe it doesn’t matter.
As an example, MKBHD’s solar roof produces something like 30KW during peak sunlight, which is so much more than his home uses (even with air conditioning turned on) that it can charge his house batteries to 100% and gives him power to sell back to the electric company for future power credits.
Admittedly, not everybody has a house with a large roof or $120K to spend on solar. But if we can drive solar and wind power down enough in price per unit, the efficiency of the storage system becomes a lot less of a concern.
Yeah at the end of the day renewable energy is rapidly becoming pretty close to free. Efficiency doesn’t matter as much when the energy costs nothing to generate.
