- United States has expanded battery manufacturing capacity to roughly 145 GWh this year, enough to meet all domestic grid‑storage demand and poised to outstrip demand by year‑end.
- Energy‑storage demand in the U.S. is projected to rise 21 % in 2024, driven by renewable‑energy deployment and the rollout of data centres.
- Inflation Reduction Act incentives cut battery‑making costs by up to 30 % and attracted about $20 bn of Korean investment, especially from LG and Samsung.
- Noah Roberts, executive director of the U.S. Energy Storage Coalition, says the United States now can supply 100 % of domestic storage projects with American‑built systems—a shift from a year‑and‑a‑half ago.
- LG Energy Solution Vertech launched a $1.4 bn cell line in Holland, Michigan, adding 16.5 GWh capacity and targeting 50 GWh across North America by year‑end.
- International Energy Agency warns that essential battery‑material supply chains remain heavily concentrated in China, and the United States has imported over $100 bn of batteries and components since 2021, about half from China, posing a supply‑security risk.
Why it matters: U.S. battery makers now control enough capacity to meet all domestic storage needs, cutting reliance on imports and boosting the clean‑energy rollout, while Chinese suppliers face reduced sales of finished cells. Yet, the U.S. still imports the majority of critical raw materials, leaving the supply chain exposed to geopolitical risk.
