US Battery Storage Expands Amid EV Slump

The story is slightly reframed: the main constraint is now described less as tariff uncertainty and more as trade-policy and tax-credit uncertainty, with permitting delays added as a clearer deployment bottleneck. The updated version also emphasizes that EV manufacturing overcapacity will not fully be absorbed by storage demand.

The story has narrowed from a broad global energy-transition investment trend to a more specific US battery-storage supply-chain and buildout story. The new emphasis is on how data-center demand, EV-factory conversions, and policy-driven domestic-content constraints are accelerating storage while exposing bottlenecks in components and imports.
