Software Due Diligence on CMBlue Energy Ahead of Investment by Globally Operating Technology and Construction Company STRABAG

CMBlu Energy develops and produces high-performance batteries. Their Organic SolidFlow batteries use carbon-based molecules and are free from critical, flammable, or explosive materials, including lithium, making them safe, scalable, affordable, recyclable, and long-lasting. With the Organic SolidFlow battery, they deliver an extremely safe and sustainable key technology for the energy transition and a broad number of applications.

By investing in CMBlu Energy, STRABAG is planning to speed up the development of specific large energy storage projects through their support with construction and infrastructure. Both companies complement each other and aim to give the energy transition a substantial boost. For STRABAG, this is the first investment into an energy storage producer, supporting CMBlue Energy to implement this crucial technology for the energy transition globally and at a large scale. Ahead of the deal, Philipps & Byrne was requested to conduct a thorough Due Diligence on the software at CMBlue Energy to provide a solid risk and opportunity assessment, supporting STRABAG’s investment decision. The €100 million funding CMBlue Energy received from STRABAG will flow into necessary investments which will help scale up the production as well as further developing the market.


About CMBlue Energy
Since its foundation in 2014 CMBlu Energy AG in Alzenau in the Rhine-Main Area, Germany, develops Organic SolidFlow batteries and is one of the largest developers of high-efficient energy storage systems on a non-lithium-ion basis in the multi-megawatt range.

SolidFlow batteries store energy in organic molecules – similar to nature. They are secure, sustainable, and affordable, the raw materials are environmentally friendly, abundantly available, and not based on insecure supply chains or conflict-ridden, environmentally harmful methods. This turns the SolidFlow energy storage systems into a crucial key component for building a global climate-neutral energy system.

CMBlu Energy employs over 190 employees in Germany and the USA – 100 of which work in research and development. With the upcoming serial production and market entry of their energy storage systems in Europe and the USA, the company is focusing on a clear course of growth.
