If you are a home energy storage provider dealing with high lithium costs and supply chain risks — this project developed a modular sodium-ion system with units of 6.2 kWh that offers a carbon footprint under 100kgCO2eq/kWh.
Sustainable Sodium-Ion Batteries for Low-Cost Industrial and Home Energy Storage
Imagine a battery that works like the ones in your phone but uses common salt instead of expensive, rare minerals. It's designed to be safer, cheaper to make, and much easier to recycle. These batteries are built to last for over 15 years, making them perfect for storing power in homes or large power plants.
What needed solving
Current battery technology relies on expensive, critical, and often toxic materials like lithium, leading to high costs and unstable supply chains. There is a critical need for a sustainable, low-cost alternative for stationary energy storage.
What was built
A non-lithium modular battery system based on sodium-ion technology, including sustainable mass-manufacturing processes for all cell components.
Who needs this
Who can put this to work
If you are a utility company dealing with the need for massive energy reserves — this project developed a non-lithium battery capable of scaling to multiple MWh with a round-trip efficiency over 95%.
If you are a battery producer dealing with expensive raw materials and toxic waste — this project developed a sustainable mass manufacturing process for sodium-ion cells using non-critical materials.
Quick answers
What is the expected cost of the storage capacity?
The project targets a CAPEX of less than 150 €/kW storage capacity.
Will this be produced at an industrial scale?
Yes, the project specifically aims to demonstrate production processes for anodes, cathodes, electrolytes, and cell production at an industrial mass manufacturing scale.
What are the IP and licensing prospects?
Based on available project data, the project involves a consortium of 13 partners including 8 industry players, suggesting a collaborative development of a European-based value chain.
What is the expected operational lifespan?
The batteries are designed to be durable for more than 15 years and exceed 5,000 cycles.
How does it integrate into existing energy systems?
It is designed as a modular battery system suitable for everything from domestic installations to large utility-scale MWh installations.
Who built it
The consortium is heavily industry-weighted with 8 industrial partners (62% of the group), including 3 SMEs. This strong commercial presence, combined with 3 universities and 2 research centers across 7 countries, indicates a high focus on commercial viability and industrial scaling rather than pure academic research.
