Sodium-Ion	120-160	1500-2000	80-150
Solid-State (Projected)	300-500	800-1200	100-250

The table above illustrates a comparison of different battery chemistries, highlighting the trade-offs between energy density, lifespan, and cost. Sodium-ion batteries, for example, offer a potentially more sustainable alternative to lithium-ion, utilizing more abundant and readily available materials. However, they currently have lower energy density. The projected figures for solid-state batteries underscore their potential to surpass lithium-ion in all key performance metrics, but significant challenges remain in scaling up production and reducing costs.

Beyond Batteries: A Holistic Energy Strategy

While the "battery bet" is significant, relying solely on batteries as the solution to our energy storage needs is short-sighted. A comprehensive energy strategy should incorporate a diverse portfolio of technologies, including pumped hydro storage, compressed air energy storage (CAES), and thermal energy storage. These technologies have different strengths and weaknesses and are ideally suited for different applications. Pumped hydro, for instance, is a mature and well-established technology, capable of providing large-scale, long-duration energy storage. CAES, on the other hand, offers a cost-effective solution for grid-scale storage, but requires specific geological conditions.
