US ‘multi-day’ energy storage startup Noon Energy has announced an agreement with Meta to reserve up to 1GW/100GWh of long-duration energy storage (LDES) capacity.

The Minnesota Public Utilities Commission (MPUC) has approved a 200MW expansion of utility Xcel Energy’s Capacity*Connect virtual power plant (VPP) programme.

The Michigan Public Service Commission has approved six battery energy storage system (BESS) projects totalling 1,332MW of capacity in the US state.

Form Energy, Noon Energy and Ore Energy are all commercialising proprietary 100-hour battery technologies for LDES applications, but how do they compare on metrics like cost, energy density and round-trip efficiency? We look at what they have revealed, as well as what they haven’t.

Form Energy has signed a 12GWh supply agreement in the US for its iron-air batteries with AI data centre infrastructure developer Crusoe.

A first project outside the US has been announced by Form Energy, the developer of a novel battery technology promising ‘multi-day’ duration energy storage.

In this US news roundup, updates on solar-plus-storage projects from Google and DTE Energy, Sunraycer, Invenergy and SRP, Idemitsu Renewables, and Clēnera.

A total of 6.9GW/17.1GWh of grid-scale BESS came online last month, as per the most recent figures from Benchmark Mineral Intelligence.

Recently, utility Xcel Energy announced it would install 30GWh of US startup Form Energy’s iron-air batteries at a data centre in Pine Island, Minnesota, owned by tech giant Google.
