CMBlu Energy, founded in 2014 and based in Alzenau, Germany, specializes in developing and manufacturing long-duration energy storage solutions. The company creates innovative Organic SolidFlow battery systems that use carbon-based molecules instead of traditional metal-based materials. This approach sets CMBlu Energy apart in the battery industry by offering sustainable and efficient alternatives to conventional lithium-ion batteries. Their technology addresses crucial market needs for safe, environmentally responsible, and scalable energy storage solutions, particularly in utility-scale and industrial applications.
Battery Technology
The Organic SolidFlow battery technology developed by CMBlu Energy represents a significant advancement in energy storage. This system combines elements of flow and solid-state battery designs, utilizing carbon-based molecules as the primary active material. The batteries operate with aqueous electrolytes, eliminating fire hazards and ensuring safe operation across various environments.
A notable feature of this technology is its modular design, allowing independent scaling of power and energy capacity. This flexibility makes it suitable for various applications, from large utility installations to commercial energy storage systems. The batteries deliver optimal performance in the four to twelve-hour duration range, making them particularly effective for long-term energy storage needs.
The system’s components are either recyclable or reusable, supporting sustainable manufacturing practices. By avoiding rare metals and conflict minerals, CMBlu Energy has created a more stable and environmentally conscious supply chain. The manufacturing process utilizes standard industrial equipment, enabling local production and simplified maintenance procedures.
Recent Projects
In 2024, CMBlu Energy initiated two significant projects. The company partnered with Salt River Project (SRP) to implement a 5 MW, 10-hour-duration energy storage system in Phoenix, Arizona, scheduled for completion by December 2025. This installation will power approximately 1,125 homes.
Additionally, CMBlu Energy collaborated with WEC Energy Group and the Electric Power Research Institute on a 1-2 MWh pilot project at Milwaukee’s Valley Power Plant, focusing on testing battery performance over extended discharge periods.
Investors
STRABAG SE stands as a primary investor in CMBlu Energy, having invested €100 million ($106.7 million) in October 2023. This strategic investment strengthens CMBlu Energy’s manufacturing capabilities in Europe and the United States while supporting the expansion of their Organic SolidFlow battery technology.
