Which is why Charging of EV batteries (or home ones to) will eventually be FREE in exchange for the benefit to th e grid when needed. Eventually we will get to having DOUBLE (or more) the solar and wind capacity than we "need" in order to have enough to bank up when they are not available. That may seem wasteful, but it is only a factor of 2 increase in investment which is small considering the cost of solar and wind have come down a factor of Ten just in the last decades. And will continue to fall.
But until the utilities put the buy-back into their tariffs to the end consumer, a home battery is not of much value.

Both Germany and California (Texas?) curtail large amounts of renewable generation. Battery storage works well for short term, small scale storage. It doesn’t work well for grid scale, seasonal storage. Here’s one chart (from the EU) that gives a view of appropriate technologies given the application. https://images.app.goo.gl/9rkqbwvBe6fw9cvA6 - Mark Sent from my Fuel Cell powered iPhone > On May 20, 2020, at 6:55 AM, Peri Hartman via EV <ev@lists.evdl.org> > wrote: > > At some point, we're going to need lots of grid storage.
