LDES lands, sodium-ion signs 60 GWh, and US solar manufacturing hits 3 GW

Long-duration storage moves from projected to operational, sodium-ion scales to a commercial supply agreement, and the US gets its largest domestic solar cell factory expansion.

Elestor hydrogen-iron flow battery partners with Europe's largest wind farm

Dutch firm Elestor signed a phased deployment agreement with Windpark Zeewolde for a 20 MW, 10-to-40 hour duration system using hydrogen-iron flow battery chemistry — 200 to 800 MWh total capacity. A pre-commercial unit targets 2025 validation; the full system targets 2031.

Why it mattersCo-locating 10-to-40-hour LDES with a gigawatt-class wind farm is the operating model long-duration storage has been projecting for years; Elestor is actually building it.

HyperStrong deploys sodium-ion BESS in 2026 with 60 GWh CATL supply deal

Chinese BESS integrator HyperStrong will deploy a sodium-ion battery energy storage system in China in 2026 for technical verification, with international rollout targeting 2027, backed by a 60 GWh cell supply agreement with CATL. The chemistry eliminates active cooling requirements in harsh climates.

Why it mattersThe 60 GWh CATL supply agreement reveals CATL's sodium-ion commercialisation route — feeding integrators at volume rather than direct project sales — and marks sodium-ion's transition from lab chemistry to fielded product.

Hithium wins EU81M grant for Spanish battery gigafactory

Chinese BESS manufacturer Hithium received an EUR81 million grant from Spain's RENOVAL 2 scheme for a battery and BESS manufacturing plant in Navarre, with total investment of approximately EUR405 million targeting commercial production in 2027.

Why it mattersA Chinese battery OEM extracting EU state aid for a Spanish gigafactory stress-tests the EU battery sovereignty strategy: cells produced in Navarre qualify under EU local content rules — the lever European automakers need for domestic content credits on EU-sold vehicles.

ES Foundry reaches 3 GW solar cell capacity at South Carolina plant

ES Foundry completed a factory expansion at its South Carolina facility, reaching 3 GW annual capacity for PERC bifacial solar cells — one of the largest US-based solar cell manufacturing footprints by nameplate. Modules built from these cells qualify for the full 10-point IRA domestic content bonus on the Investment Tax Credit.

Why it mattersUS domestic solar cell manufacturing has lagged downstream module demand; this expansion closes a supply gap that directly affects project-level economics for utility-scale solar developers seeking the maximum IRA incentive.

Argentina closes 700 MW BESS procurement in single tender

Argentina's AlmaSADI tender awarded contracts totalling 700.5 MW of battery energy storage, part of a programme adding dispatchable capacity to a grid strained by demand growth.

Why it mattersA 700 MW single-tender award puts Argentina in the same procurement weight class as mid-sized European markets — a signal that Latin America's grid storage build-out is arriving, not still being projected.

Water-jet process recovers 97%-pure silver from solar modules

Researchers developed a high-pressure water-jet delamination process for photovoltaic module recycling that physically separates cell layers without acid or thermal treatment, recovering silver contacts at 97% purity — directly smelter-ready — while also yielding intact silicon cells and glass as separate streams.

Why it mattersAs 2010s utility-scale solar installations approach replacement cycles, end-of-life economics matter; 97% purity from a physical process changes the recycling margin calculation compared to existing chemical routes.
