Seeking pilot opportunities to demonstrate copper redox flow batteries in long-duration energy storage cases

CuRen is a research project jointly supported by Aalto University and Business Finland, with the objective of commercialising a long duration battery technology based on copper redox flow chemistry (CuRFB).

Copper RFBs hold an advantage over existing BESS systems for stationary and grid usage, due to the ability to hold discharge over long periods of time (4 to 16 hours) at relatively high efficiency rates. Savings on the levelised cost of storage are achieved based on the simplicity and modularity of manufacturing and installation. The system does not degrade over time, and does not face inherent electrical and fire risks as other battery technologies.

CuRen is currently seeking interested stakeholders in this copper-based battery technology, and is aiming to conduct full scale pilot testing (3 to 6 months) by pairing with wind and/or solar generation assets, to evaluate operating conditions and validate lab-based test results.
