America's Battery Ban Could Cost the Grid
A Trump executive order banning Chinese grid batteries arrives just as US storage demand hits record highs — and domestic supply can't yet fill the gap.

The US energy storage market is growing faster than ever, powered largely by the Chinese lithium iron phosphate cells it is now trying to ban. In late August, the Trump administration declared a national emergency and moved to prohibit Chinese batteries from grid-scale energy storage systems — a move that analysts say will slow deployment and could cancel projects outright.

The scale of the dependency is stark. Total US lithium-ion battery demand is expected to reach 182 GWh in 2026, with 37% of that coming from the stationary storage market — and the US remains heavily reliant on Chinese imports for those cells. [2] New tariffs had already pushed Chinese battery imports to their lowest level since 2021, but the executive order goes further, banning installation of any foreign-produced bulk-power system electric equipment that poses a national security risk. [1][2]
The immediate fallout looks painful. Projects could face delays as developers wait for guidance from the Department of Energy, expected by year's end. Alternatives — whether domestic cells or imports from South Korea — will cost more than Chinese equivalents. Import taxes for batteries already increased to 25% in January, up from 7.5%, compressing margins further. [1]
Domestic relief is years away. The US could have enough manufacturing capacity by around 2030, but supply won't realistically match demand until later in the 2030s. New factories from LG Energy Solutions, Samsung SDI, Ford, and SK On are set to ramp up by next year — and in an ironic twist, a slowing EV market is helping, as some factories originally designed for vehicle batteries are retooling to build cells for grid storage instead.

The tension here is one every major economy faces: cheap, available technology on one side; supply-chain sovereignty on the other. Neither instinct is wrong. The cost of getting the balance right, though, will be paid by the grid first.
Starting in 2026, new legislation requires that 55% of the cost of materials used for new energy storage projects come from outside China and other restricted countries — or those projects lose their tax credits entirely. [1] The policy architecture is tightening fast. The manufacturing base has not caught up.
