Energy storage news: battery projects, grid scale BESS, long duration storage, sodium ion and new chemistries, markets and prices.

The United States installed 9.7 GWh of new energy storage capacity during the first quarter of 2026, setting a record for the period and reinforcing how rapidly battery deployment is becoming tied to grid reliability concerns, electricity price volatility, and the accelerating power requirements of artificial intelligence infrastructure.

At a time when the United States is scaling grid storage capacity beyond 25 GW of operational battery systems and adding hundreds of megawatts of new installations each year, POET and Antora Energy’s deployment of a 5 gigawatt hour thermal energy storage facility in Big Stone City, South Dakota signals a parallel but less conventional trajectory: industrial heat decarbonization anchored in high temperature carbon based storage rather than electrochemical batteries.

The United Kingdom’s energy transition is entering a phase where storage duration is becoming as strategically important as generation capacity itself. As renewable penetration increases and periods of excess solar and wind generation become more common, the limitation is no longer only how much clean electricity can be produced, but how long it can be retained and dispatched when needed.
