Organic SolidFlow Energy Storage Systems

Produced in our new Battery Production Center in Alzenau. We drive the energy transition forward.

Nature is our model

At CMBlu Energy our approach is simple. We look to nature to make technology better. By imitating carbon-based molecules from the citric acid cycle in our bodies, we developed high-performance energy storage molecules that are entirely organic. The result is simply revolutionary: a green battery that enables large-scale, affordable, and customizable energy storage. 

CMBlu Energy started as a research-driven project in 2011. Since then, we have continued to expand our broad IP portfolio and energy storage expertise. Today, we are the world's leading company in the field of organic solid-flow batteries and a major German battery manufacturer based in Alzenau, Germany. Together with our partners, customers and employees, we are advancing the key technology for the energy transition.. 

CMBlu milestones

    CMBlu Energy Inc., our US-subsidiary has been established in Petaluma, California, to respond to the importance of the USA as one of the largest and most dynamic energy storage markets of the future.

  • Groundbreaking Joint Venture with state-owned utility UNIPER: the pilot project at the Staudinger power plant in the Rhine Main Area will qualify CMBlu's SolidFlow technology for the participation in the European energy market.

  • CMBlu has been audited by TÜV SÜD and is now certified according to the following ISO norms:

    ISO 9001 (Quality Management System)

    ISO 14001 (Environmental Management System)

    ISO 45001 (Occupational Health and Safety Management System)

  • CMBlu makes the Burgenland in Austria "energy self-sufficient" by 2030. The Governor of Burgenland signed a cooperation agreement between Burgenland Energie and CMBlu.

  • The go-ahead has been given to start the prototype production of our organic solid-flow energy storage systems. With the new Battery Production Center BPC directly at the Alzenau site, we are approaching series production with great strides.

  • A separate depot was added to the tank, in which most of the energy is stored chemically in solids. From now on we speak of "Organic SolidFlow batteries". This patented technology is a huge step. Not only for us!

  • 2020

    Our green battery solutions continue to grow, with our CMBlu Stack Version 2.0, a commercial-scale battery with up to 100 cells.

  • 2021

    And grow: we launch the first system with 6x100 cells, BMS and power electronics, for even larger applications and precise performance monitoring.

  • 2018

    The first high-performance PEP electrolyte joins our growing IP portfolio which we have been honing since 2011.

  • 2019

    Our company’s headcount increases to 80 employees.

  • 2016

    We succeed in building the first large-scale stack – a big step for the bulk energy storage for multiple applications.

  • 2015

    We premiere the first lignin-based fully organic battery, making the electrolytes especially economical to source and safe to use.

  • 2014

    Promising research results lead to the founding of CMBlu Energy AG in 2014. Major partnerships are established and a strategic focus is put in place. 

  • 2013

    We develop the first multi-cell stack design, one of the early cornerstones of our scalable green batteries.

  • 2011

    In 2011 a small team headed by founder Dr. Peter Geigle starts investigating organic flow technology.
