Yeah, Form Energy exists to basically disprove this: Batteries will still be too expensive to arbitrage these seasonal differences effectively. Thermal electricity storage is orders of magnitude cheaper for storage, but worse at daily cycling Form, like the authors, agrees that Lithium-ion is great for intra-day cycling and not suitable for is seasonal storage. Unlike the authors, Form believes it can engineer chemical storage with the requisite properties. Form’s batteries have something like 10 days of capacity relative to the size of their inverters.
