grid storage

ESS Tech and Juniper Energy signed a non-binding LOI to deploy 500+ MWh of sodium-ion storage, starting with an 80 MWh California project targeted for 2027.

The agreement covers five initial projects and targets a program exceeding 100 GWh, with Tesla supplying Megapack hardware, construction, and Autobidder trading.

General Motors will design a sodium-ion cell at its Warren, Michigan battery labs and retain exclusive rights to manufacture it, while GM Ventures takes a strategic stake in partner Peak Energy.

The DOE's Grid Storage Launchpad has commissioned the first prismatic battery cell production line at a US national laboratory, starting with sodium-ion and LFP chemistries.

Invinity Energy Systems has delivered 90 vanadium flow batteries to the Copwood VFB Energy Hub in East Sussex, forming Europe's largest such installation at 20.7 MWh, backed by UK government funding.

A team at the Institute of Metal Research engineered a new iron-complex electrolyte that ran 6,000 cycles at 80 mA per square centimeter with no capacity decay and a 99.4 percent average coulombic efficiency, opening a possible low-cost route to long-duration grid storage.

The three-year agreement, equal to half of CATL's 2025 storage shipments, signals that sodium-ion has cleared its mass-production hurdles and is moving from pilot projects to grid-scale deployment.

Chinese battery makers are racing to add stationary-storage capacity while Beijing phases out export rebates, a shift that could tighten margins abroad and deepen domestic grid-storage demand.

The MIT spinout plans to demonstrate a 1 MWh thermal battery in Bedford, Massachusetts this year, using graphite bricks heated to 2,400 degrees Celsius and liquid tin to deliver grid-scale storage at a claimed $25 per kilowatt-hour, a fraction of lithium-ion costs.

Peak Energy and RWE Americas have deployed the first sodium-ion battery system on the MISO grid in Wisconsin, marking a milestone for the cheaper, cobalt-free chemistry in the US.
