Uniper Signs 5GWh Conditional Supply Agreement for CMBlu’s Organic Flow Batteries
German utility Uniper has signed a conditional supply framework with CMBlu Energy to procure at least 5 GWh of the firm’s organic solid‑flow batteries. The agreement, running through 2037, allows Uniper to take delivery in 100 MWh blocks beginning in 2027 after a successful site‑acceptance test. CMBlu’s SolidFlow technology combines organic redox‑flow chemistry with solid‑state storage, offering decades‑long life, non‑flammable electrolytes and no reliance on lithium, cobalt or nickel. The deal marks a notable shift toward large‑scale, non‑lithium storage in Europe.
