## About

Based in Germany, and founded in 2014, CMBlu Energy AG operates as a provider of clean technology that manufactures renewable batteries by grid operators, for commercial and industrial used. As of October 2024, Constantin Eis is the Chief Operating Officer (CEO) of the company.

CMBlu Energy AG focuses on creating energy storage solutions, especially with its main product, the Organic SolidFlow battery. The company's battery design keeps the power generating parts separate from the storage tanks, that lets it adjust power and capacity separately to fit different needs, including voltage levels. The Organic SolidFlow battery can be used for multiple purposes, such as storing renewable energy, supporting electric vehicle charging, and managing energy for industrial sites. The firm mainly serves clients in the renewable energy, transportation, and industrial sectors, focusing on markets in Europe, North America, and other parts of Asia.

In April 2026, CMBlu Energy AG raised EUR 50 million in series C funding from Samsung NEXT Ventures, with participation from Strabag, valuing the company at EUR 1 billion post-money.
The company plans to use the April 2026 funding to scale deployment of its SolidFlow long-duration energy storage systems to support always-on power needs for AI workloads and data center customers.
