It's also just not a matter of cost but supply. Even if you had the money for enough batteries to meet storage requirements for a fully green grid there is almost no chance you could manufacture enough cells.
For the forseeable future all cell production is going to go into cars because Tesla has fat enough margins to absorb increases in battery costs while utility scale storage can't.
- SEJeff 5y agoTesla is putting significant new investment into their energy business. Since they now have almost every major battery manufacturer globally doing business with them, they can shift to the less automotive grade chemistry for their stationary energy storage (power packs and mega packs). Elon’s literal words mention this: https://www.utilitydive.com/news/musk-vows-to-accelerate-tesla-solar-and-energy-storage-business-in-2022/617830/ https://www.utilitydive.com/news/musk-vows-to-accelerate-tes...
- jpgvm 5y agoJust because they will start using LFP for stationary storage doesn't mean they also won't consume all of the LFP capacity for cars and starve out stationary storage again. They already used LFP for all the China built M3s and started shipping those same M3s to non-Chinese markets. Right now all signs point to this continuing. Margins on cars are much better, right now cell supply is so constrained but demand for Teslas is so high they only manufacture the highest spec SKUs. If there are more cells they will go into producing first lower spec cars and then finally stationary packs will get whatever is left (if any).
