Alfen and CATL have committed to deploying 5 GWh of sodium-ion battery storage systems across Europe, expanding their existing lithium-ion partnership and signalling a shift toward alternative battery chemistries for grid-scale storage.
This Wire brief sits within Fusion42's coverage of Climate Tech. Wire is Fusion42's founder-focused intelligence feed: each story is connected to the funds and startups it names — every one with a live profile on Raise or Scout — so founders can follow the capital and the momentum behind the headline rather than just the headline itself. Wire analysis is one of the live surfaces Arthur reasons over.
◆ ◆ The Wire takeaway
If you make materials, cooling systems, or balance-of-system components for grid batteries, CATL just committed 5 GWh of sodium-ion capacity to Europe - that's a new bill of materials and a new supply chain to sell into. Sodium-ion is cheaper and more abundant than lithium, which means your lithium-specific optimisations are now competitive liability.
