Supply Chain Bottlenecks Slow US Battery Storage Deployment

Battery costs have dropped enough to make grid-scale storage economically viable, but American manufacturers lack production capacity and component supply chains to meet demand. Cheaper technology isn't translating into faster grid modernization. This creates an opening for Chinese competitors to establish manufacturing dominance in energy storage as US utilities scramble to integrate renewables at scale. Regulatory and financial barriers have been solved; industrial execution is now the bottleneck.
