You need to overbuild solar with a factor of 5 to get to a practical amount of batteries. See https://twitter.com/sytses/status/1441605024887427073?s=21 https:/

One side benefit of that is that energy will be free 90% of the time. Great for carbon extraction and desalination.
- bigfudge 5y agoThat presumably ignores the fact that other industries would adapt to respond to energy that was essentially free for even shorter periods. The economics of heavy industries might change if the energy input was free for 3 hours a day (e.g. offsetting great capital spend to overbuild infrastructure there).
- Ajedi32 5y agoOverbuilding by 5x means you also need to multiply the cost by 5x. Is solar still cheaper than nuclear once you factor that in? (Not to mention the cost of energy storage.)
- pydry 5y agoIn Iceland probably not, in Hawaii hell yes.
- mrep 5y agoHas he never heard of power to gas [0]? We already have lots of storage and generators for natural gas. I doubt you'd need more than twice the capacity using power to gas. [0]: https://en.wikipedia.org/wiki/Power-to-gas https://en.wikipedia.org/wiki/Power-to-gas
