Cella has developed a novel hydrogen storage material capable of releasing large quantities of hydrogen when heated to temperatures above 100°C. The material makes the storage and transportation of hydrogen at room temperature and pressure possible and safe.


Cella Energy was co-founded by Professor Stephen Bennington in January 2011 as a spin-out from the UK Government’s Science and Technology Facilities Council. The vision was to build a company around a novel hydrogen storage material that is stable and safe to handle at room temperature, but releases large quantities of hydrogen when heated above 100°C. A material that can be produced inexpensively and in large quantities; one that does not require high-pressures or high-temperatures or expensive and complex infrastructure. In short, a material that makes the hydrogen economy a practical reality.

Research into Cella’s material and processes began in 2007, led by Stephen Bennington and his team at the Rutherford Appleton Laboratory, and with students and staff from both University College London and the University of Oxford.

During the first two years, the Company developed the material and production methods to the point where it is now able to make meaningful quantities and with its partners developed two demonstration power supplies: one for an unmanned aerial vehicle and larger one suitable for automotive or aerospace applications.
