Sustainable European Sodium-Ion Battery Systems for Large-Scale Energy Storage

energyPilotedTRL 7

Imagine a battery that doesn't rely on expensive or rare materials like lithium, using common salt-based elements instead. This project builds these batteries using sustainable wood-based carbon and safe materials sourced entirely within Europe. It's like switching from a rare, imported spice to a local, sustainable alternative that does the same job but costs less and is easier to find.

The business problem

What needed solving

European battery manufacturers rely on unstable, expensive, and non-European supply chains for lithium-ion materials. This creates price volatility and strategic vulnerability for energy storage systems.

The solution

What was built

Pre-industrial scale sodium-ion battery modules (>2,5kWh) featuring biobased hard carbon, Co-free layered oxides, and an advanced BMS with Battery Passport.

Who can put this to work

Renewable Energy
enterprise
Target: Grid-scale energy storage provider

If you are a grid-scale energy storage provider dealing with high costs and supply chain risks of lithium, this project developed sodium-ion modules of >2,5kWh that provide a cost-effective, Made-in-Europe alternative for stationary storage.

Forestry & Bio-materials
mid-size
Target: Sustainable timber and biomass processor

If you are a biomass processor dealing with low-value wood waste, this project developed a way to turn sustainably managed forests into biobased hard carbon for high-capacity batteries.

Industrial Manufacturing
any
Target: Battery pack assembler

If you are a battery assembler dealing with complex recycling regulations and safety risks, this project developed a sustainable-by-design cell architecture with high reparability and a digital Battery Passport.

Frequently asked

Quick answers

How does this impact the cost of battery systems?

The project aims to create cost-effective storage by using sodium-ion technology and EU-sourced biobased materials, reducing reliance on expensive imported minerals.

At what industrial scale is the technology being developed?

The project is demonstrating technology at a pre-industrial scale (TRL 7), specifically manufacturing cells up to 80 Ah and modules exceeding 2,5kWh.

What is the IP or licensing status of the technology?

Based on available project data, specific licensing terms are not listed, but the project focuses on establishing a competitive European manufacturing industry.

How is the technology integrated into existing systems?

Integration is achieved through an advanced BMS with Battery Passport capabilities and SoC management, tested across 5 different real end-user operating conditions.

What is the project timeline for commercial availability?

The project runs from 2025-01-01 to 2028-12-31, with the goal of accelerating commercialization post-project.

Consortium

Who built it

The consortium is heavily industry-driven with a 57% industry ratio (8 industrial partners out of 14), including 2 SMEs. This strong industrial presence, combined with 5 research institutions across 8 European countries, suggests a high focus on commercial viability and manufacturing scalability rather than pure academic research.
