CATL goes big, sodium-ion finds its data centre customer, and China owns electrolysers

The world's largest battery maker doubles its flagship BESS container size, a GM-backed startup positions sodium-ion cells for AI data centre demand, and a Heatmap investigation finds the West invented the clean hydrogen machine but China is building the industry.

CATL launches its 9 MWh TENER+ battery storage system globally at All-Energy Australia

CATL held the worldwide commercial launch of its TENER+ 9 MWh battery energy storage system at the All-Energy Australia conference in Melbourne, simultaneously announcing a power conversion system partnership — the largest containerised BESS product in CATL's commercial line-up, positioning it to compete directly with 4-hour long-duration products from Tesla Megapack and Fluence.

  • 9 MWh per container roughly doubles the capacity of CATL's prior flagship TENER product
  • Launched at All-Energy Australia alongside a simultaneous global PCS supply partnership agreement
  • Targeted at utility-scale 4-hour duration grid applications in the US, Europe, and Australia
Why it mattersWhen the world's largest battery manufacturer doubles its flagship container size, the benchmark for utility BESS shifts and every competing integrator has to respond.

GM-backed Peak Energy is scaling sodium-ion cells specifically for AI data centre demand

Peak Energy, backed by General Motors, advanced plans for its Sacramento production facility to focus on sodium-ion battery cells aimed at stationary storage for AI data centres — explicitly structuring manufacturing to avoid the capital-intensity traps that collapsed several Western gigafactory builders.

  • Sodium-ion chemistry requires no lithium, cobalt, or nickel — supply chains outside China's dominant position
  • AI data centre customers provide high-density commercial anchor before wider utility grid expansion
  • Manufacturing approach prioritises equipment standardisation and capital efficiency over raw throughput targets
Why it mattersIf sodium-ion can serve AI data centre demand at scale, it removes the critical mineral bottleneck on the largest new electricity load being added to the grid.

The West invented the electrolyser. China is building the industry.

A Heatmap News investigation found that while European and American companies developed the core electrolyser technology for hydrogen production, Chinese manufacturers have captured dominant manufacturing scale, cut costs by roughly 70% in five years, and are now exporting at prices Western producers structurally cannot match.

  • Chinese electrolyser costs have dropped approximately 70% since 2021 on manufacturing scale and state support
  • European and US electrolyser manufacturers face a cost-per-unit gap approaching 3-4x vs Chinese competitors
  • Pattern mirrors the solar PV and battery industry trajectories from the previous decade
Why it mattersThe electrolyser cost curve following the solar and battery playbook is a warning for any Western clean-energy manufacturing sector that delays scale-up.

Renault and EDF are planning a vehicle-to-grid charging offer for 2027

Renault Group and EDF announced a partnership to develop a joint vehicle-to-grid (V2G) service for French consumers, targeting a commercial offer in 2027 that would allow compatible Renault EVs to export power back to the grid through EDF's residential energy platform.

  • 2027 commercial target for French market V2G service combining Renault vehicle hardware and EDF energy management
  • Builds on Renault's existing bidirectional charging capability in several models including the Megane E-Tech
  • Positions EDF to monetise distributed EV storage as France's renewables penetration and grid balancing needs increase
Why it mattersA major utility and a major automaker committing to a 2027 V2G commercial service is the clearest signal yet that distributed EV storage will reach retail consumers in Europe before the end of the decade.

LG Energy Solution signs a 4.5 GWh MOU with Energix for US and European BESS deployments

LG Energy Solution signed a memorandum of understanding with US-Israeli developer Energix for up to 4.5 GWh of potential battery energy storage system deployments across projects in the United States and Europe, representing one of the larger BESS supply commitments disclosed this quarter.

  • 4.5 GWh potential represents a significant order pipeline across multiple grid-scale projects
  • Energix operates in both US and European markets, providing LG Energy Solution geographic diversification
  • Deal reinforces LG Energy Solution's BESS supply position as CATL and BYD intensify European competition
Why it mattersA 4.5 GWh MOU is a leading indicator: it signals where grid storage deployment capital is being committed 18-24 months ahead of project completion.

Data centres could accelerate sodium-ion and long-duration storage adoption across Europe

An analyst report highlighted by Energy-Storage.news found that AI and cloud data centre load growth could be the commercial catalyst that makes sodium-ion batteries and long-duration energy storage economically viable in European markets, providing the high-cycle demand profile that grid-only applications have struggled to underwrite.

  • Data centres provide predictable, high-cycle demand that matches sodium-ion's cycle-life strengths
  • LDES products require behind-the-meter anchors to achieve the utilisation rates needed for positive IRR
  • Europe's renewable build-out creates both the grid-balancing need and the colocation opportunity simultaneously
Why it mattersData centre demand as the anchor customer for new storage chemistry is the same dynamic that grid-scale batteries needed retail EVs to play in the 2010s — it accelerates the cost curve by years.
