The fact is that we exist today in exactly the state that is being promoted as beyond solution. Our present renewable generation and present ready storage are exceeded, and we rely on a 3rd-line backup, fossil fuels. Each increment of renewable generation and storage added reduces the amount of fossil fuels that must be used.

Factories for any form of storage are not different in any material way from a thousand other factories we know work. We have been making factories for going on three centuries, and know we can. Making and operating factories is expensive capex, but exploring, extracting, transporting, and refining fossil fuels is an even more expensive opex. If we could afford fossil opex, renewable capex of similar order is strictly better.
