No, i do accept that Solar and Wind can supply the main amount of electricity, most of the time, but they cannot supply ALL the electricity ALL of the time… and to do that using gas plants or batteries, would be impossibly expensive
You keep presenting your "all or nothing" argument, and ignoring the time it takes to bring your blue sky "someday, maybe" white hydrogen online. *If ever*
PV with buffers made from used EV packs is the cheapest, fastest to build, quickest to respond to load changes, cleanest and lowest cost to retire system of any energy production scheme. If all they do is let utilities keep their gas turbines off twenty days a month, or ramping up and down much less frequently in a day, that's a win. Much less NG burned in a year.
And that combination is only going to look better as more companies get involved, PV panels improve, and production comes onshore.
One more time...the back order time on gas turbine generators is *seven years* Restarting old nuke plants will take years, and consistently go over budget by two or three times the estimated cost, IF it's ever accomplished. New nuke plants take a decade to come online, and are more expensive per megawatt than any other source of electricity.
The relative energy efficiency of PV plus used batteries ( when all costs are honestly figured in ) are so much better than any other system, that the likelihood of anything else coming even close in the next fifty years is very low.
The trickle down effect in themselves are valuable...
Having a reliable market for large quantities of used EV batteries, with little effort needed to re-purpose them, solves several issues relative to wider EV adoption. Including making the process of replacing old pack in existing EVs cheaper, simplifying EV battery recycling, and pushing back the day when we need to be able to shred massive quantities of old cells to extract their raw materials.
Using old EV packs at EV charge stations ( as load buffers ) eases and speeds widespread installation of fast charge stations. EVs are improving in range and charge speed every year, but more charge stations will speed EV adoption.
BTU, one of the companies doing grid scale PV power with used EV packs,is even using Nissan Leaf batteries, the ones notorious for short useful life in the car ( they have minimal battery cooling ability) BTU can treat them gently enough so *that doesn't matter*
