Storage on Three Continents

Grid storage closes financings and cuts ribbons on three continents while sodium-ion confronts the bankability question for the first time at industry scale.

France's Largest Battery Goes Live at 240 MW/480 MWh

TagEnergy's Cernay-les-Reims project, built on 140 Tesla Megapack units across 3 hectares, is now France's largest operational grid battery. In its first four months it logged 145 full cycles and 70.5 GWh of returned energy.

  • 240 MW / 480 MWh connected to RTE's 225 kV grid; certified for FCR and aFRR services
  • 140 Tesla Megapack containers on 3 hectares; civil and electrical works by Eiffage
  • TagEnergy and Banque des Territoires co-own the project; Banque holds a 49% stake
Why it mattersFrance's largest BESS is proof that utility-scale lithium storage financing works in Western European markets.

Hithium's 785Ah Sodium-Ion Cell: Bankable or Just Promising?

Hithium launched a 4 MWh sodium-ion BESS cabinet alongside a new 785Ah cell, directly addressing whether the chemistry can clear insurer and lender hurdles. Its argument: higher lifetime energy throughput, not lower upfront cost, is where sodium-ion wins.

  • 785Ah cell validated to GB/T 44265; thermal propagation and financial-close tests ongoing
  • Hithium positions sodium-ion for high-cycle long-life projects, not as a CAPEX undercut to LFP
  • Bankability claim rests on LCOS over 20-30 year project life, not headline $/kWh
Why it mattersSodium-ion's path to utility scale runs through the lender's spreadsheet, not the lab - Hithium is the first large manufacturer to say that plainly.

Atmos Renewables Closes Financing on 1.6 GWh Queensland BESS

Atmos Renewables reached financial close on the 400 MW / 1,600 MWh Teebar battery project in Queensland, backed by Australia's federal Capacity Investment Scheme. The deal is among the largest CIS-backed BESS financings to date.

  • 400 MW / 1,600 MWh (4-hour duration) in Queensland; CIS backstop enabled commercial-bank debt
  • CIS has now supported multiple GWh-scale projects in 2026 as Australia's NEM storage build-out accelerates
  • Q3 2026 NEM battery revenue hit AU$88.91M, up ~40% year-on-year, underpinning investment case
Why it mattersGovernment capacity contracts are converting GWh-scale BESS from aspirational to bankable across Australia.

CIP Takes EUR 270M FID on 1.4 GWh Scottish Grid Battery

Copenhagen Infrastructure Partners committed EUR 270 million to the Kilmarnock South BESS in Ayrshire - a 350 MW / 1,400 MWh four-hour system designed to relieve chronic wind curtailment on the Scottish transmission grid.

  • 350 MW / 1,400 MWh four-hour architecture; HV substation construction now underway
  • Expands CIP's Scottish BESS pipeline to 4.4 GWh across four projects in Ayrshire
  • Positioned to absorb curtailed onshore wind from the northern grid's export bottleneck
Why it mattersA EUR 270 million FID from a major infrastructure fund confirms long-duration grid storage is clearing the private-capital bar in Europe.

Antora Energy's 5.8 GWh Thermal Storage Project Lands in Kansas

Antora Energy announced a 5.8 GWh multi-day thermal energy storage system at a Kansas biorefinery, backed by Copenhagen Infrastructure Partners - among the largest long-duration storage projects disclosed in the US in 2026.

  • 5.8 GWh of carbon-block thermal storage at Pratt Energy's biorefinery in Pratt, Kansas
  • Technology stores electricity as heat in carbon blocks for multi-day industrial dispatch
  • CIP provides infrastructure backing; operational timeline not yet disclosed
Why it mattersMulti-day industrial thermal storage reaching gigawatt-hour scale shows long-duration moving well past the four-hour lithium-ion norm.

Samsung SDI and EcoPro BM Partner on Sulfide Solid-State Cells

Samsung SDI and cathode specialist EcoPro BM signed an agreement to co-develop and mass-produce sulfide-based solid-state battery materials, scaling to metric-ton electrolyte volumes on Samsung's automated S-Line pilot, with commercial mass production targeted for 2027.

  • EcoPro BM to scale high-nickel cathode and sulfide electrolyte production to metric-ton level
  • Samsung SDI's 6,500 sq-m S-Line adapted for roll-to-roll dry electrode pressing
  • Target: commercial ASSB mass production in 2027 entering OEM validation programs
Why it mattersCathode-cell maker co-development pacts are the supply-chain step that precedes sulfide solid-state entering production - this formalizes that timeline.
