U.S. battery production tops demand
U.S. battery manufacturing capacity has now surpassed 100% of domestic demand for energy‑storage systems, marking a potential turning point for clean‑energy supply chains and grid resilience. At the same time, new tech is arriving — grid‑forming inverters, BAIC’s sodium‑ion prototype beating 170 Wh/kg, and Eve Energy’s two new all‑solid‑state products — which together could ease lithium pressure and shift where investment flows in EVs and stationary storage.

The U.S. Energy Storage Coalition released its milestone report on March 18, 2026, saying American factories now have the capacity to supply 100% of future U.S. energy storage projects with U.S.-built battery systems and power electronics. (energystorage.org) The Coalition’s “Energy Storage Powers American Manufacturing” brief says U.S. cell manufacturing could surpass domestic demand by the end of 2026 and that the industry’s buildout is expected to generate more than 350,000 new jobs. (energystorage.org) Independent trackers project U.S. energy storage cell capacity reaching roughly 50 GWh by the end of 2026, a figure cited by recent market research as evidence of the domestic scale‑up. (blackridgeresearch.com) Work on grid‑forming inverter standards and deployment is advancing alongside factory builds: the UNIFI consortium (DOE‑backed) has published GFM specifications and ERCOT approved Advanced Grid Support (grid‑forming) requirements in September 2025 as part of regional operational rules. (docs.nlr.gov) BAIC announced a sodium‑ion prototype in mid‑March 2026 that its internal tests show exceeds 170 Wh/kg in a prismatic cell format and supports 4C charging — roughly an 11‑minute full charge at the cell level, according to company disclosures reported by multiple outlets. (cnevpost.com) EVE Energy rolled two all‑solid‑state models, Longquan No.3 and No.4, off its Chengdu line on March 17, 2026, with No.4 described as a 60‑Ah EV cell and the new solid‑state pilot plant sized for about 500,000 cells (~100 MWh/year) of early production. (cnevpost.com) The IEA and industry analysts note that commercial sodium‑ion advances (e.g., CATL’s Naxtra and recent prototypes) and early solid‑state rollouts are already drawing investment and could ease pressure on battery‑grade lithium supply chains as manufacturers diversify chemistries.
