I don’t know for Musk, for Seba the solution now is overgeneration: it’s more cost effective to have excess solar than to have enough batteries. The advantage is that you have period were you have free energy if a business find a way to use it. He think that as that become common more more business will find ways to take advantage of it: H2 generation, heat storage, steel/ciment, and other things we are yet to find. I came to the same conclusion when I installed solar on my motorhome, it’s was way more effective to install "too much" solar so that I have enough for the night of a gray and cold winter day. Otherwise I would had to pay 10X more in lithium batteries. In a summer sunny day I use a fraction of the power. hopefully with a large grid and many free agent and an efficient market the free energy will find uses.
