Organic Flow Battery Firm Cmblu Wins 5MW Project Order From SRP In Arizona

Europe-based organic flow battery company CMBlu has won its second US project, a 5MW, 10-hour duration pilot system with Arizona utility Salt River Project (SRP).

SRP selected CMBlu for the project after issuing a request for long-duration storage project proposals. The Alzenau, Germany-based firm will build, own and operate the project for SRP at the utility’s Copper Crossing Energy and Research Center in Florence, Arizona.

Copper Crossing is a new power plant project combining a gas plant in phase one, followed by a 55MW solar PV plant in phase two with CMBlu’s long-duration energy storage (LDES) project coming in phase three.

Construction on the system, which will have an implied energy storage capacity of 50MWh, will start in early 2025 to be come operational by December that year. It will primarily shift solar generation from the daytime towards the evening as production begins to tail off.
