Salt River Project ("SRP"), a community-based, not-for-profit public power utility and the largest electricity provider in the greater Phoenix metropolitan area, and CMBlu Energy ("CMBlu"), a designer and manufacturer of long-duration Organic SolidFlow energy storage systems, announced a pilot project to deploy long-duration energy storage (LDES) in the Phoenix area. The 5-megawatt (MW), 10-hour-duration project, named Desert Blume, will use CMBlu's unique non-lithium technology, and the firm will build, own and operate the batteries on behalf of SRP at their Copper Crossing Energy and Research Center in Florence, Arizona. SRP is the first U.S. electric utility to implement CMBlu's batteries at this scale.
CMBlu's Organic SolidFlow battery technology uses a non-flammable proprietary mixture of solid electrolyte and water-based electrolytes with high energy density and performance. The systems are fully recyclable, free of rare metals, and housed inside buildings. CMBlu expects its battery system to cost-effectively store and deliver energy for two to three times longer per cycle than traditional lithium-ion technology, which typically targets a four-hour duration.
The project is designed to store energy for SRP's customers during daytime periods, largely from Arizona's abundant solar generation, and return that energy to the grid throughout the night. It will store enough energy to power about 1,125 average homes for 10 hours.
"We are privileged to work with CMBlu and gain experience with their extremely innovative technology," said Jim Pratt, CEO of SRP. "This resource will supplement SRP's power system helping provide stored power for longer periods, especially in times of fluctuating, high energy demand from customers in the Valley. It will be a helpful addition to SRP's significant number of renewable resources and storage projects, which generally only store energy for up to four hours."
"Desert Blume is a critical project to validate Organic SolidFlow batteries at scale and promote safe, sustainable, and secure long-duration energy storage built in the United States," said Ben Kaun, President of CMBlu Energy's U.S. division. "We're thrilled to collaborate with SRP to support their rapid clean energy transition, as well as have the opportunity to demonstrate our technology in the Southwestern U.S. Phoenix anchors one of the country's fastest growing metro areas, with abundant solar potential, making it an ideal environment for the next generation of LDES."
This pilot is part of an approved third phase of continued development at SRP's Copper Crossing Energy and Research Center in Florence. The first phase will add two flexible natural gas turbines with a total output of less than 100 MW, and the second phase will add a utility-scale advanced solar generation facility capable of generating up to 55 MW of solar energy.
SRP selected CMBlu after issuing a request for long-duration storage project proposals from emerging energy storage companies. The Electric Power Research Institute (EPRI) will support performance monitoring of this pilot project and help validate the real-world performance of the technology in Arizona's hot and dry climate.
The SRP pilot in Florence represents the latest application of CMBlu's technology following several other project announcements this year. In July, CMBlu announced the first customer deployment of its battery with Burgenland Energie in Austria, and will also provide its LDES systems for a pilot in Milwaukee with WEC Energy.
Construction is slated to begin in early 2025, and SRP and CMBlu expect the pilot to be operational in December 2025.
