About

CPH2 is proud to be at the core of the green hydrogen industry.

Our passion for hydrogen as a clean energy source for the future led us to seek an alternative to PEM electrolysers, which presented adoption challenges. We learned that membrane-free water electrolysis was the cleanest method to produce hydrogen. This approach would reduce environmental impact and offer a more affordable and robust technology.

In 2012, Dr Nigel Williamson and Joe Scott founded CPH2 (Ireland) with the aim of contributing to a better environment for future generations.

To enter the green technology and renewables sector, a rapidly growing market segment, they created a highly efficient Membrane-Free Electrolyser™ to produce hydrogen faster and at a lower cost than other electrolysers on the market.

CPH2’s Vision Statement

CPH2 aims to be a globally recognised designer and manufacturer of Membrane-Free Electrolysers™. To reduce the creation of harmful emissions by participating in the growth of the hydrogen economy.

Our History

  • Clean Power Hydrogen Group Limited is established in the UK by founding members Dr. Nigel Williamson and Joe Scott, following the company being established in Ireland in 2012.
  • Successful demonstration to show proof of concept to separate hydrogen and oxygen using a simple liquid nitrogen-cooled cryogenic system.
  • Successful trials to reduce NOx emission by 50% on a diesel generator completed. The 440 kW generator was operated at 100% power and the emissions reduced from 680 ppm to 306 ppm, at 75% power with a reduction from 589 ppm to 341 ppm and at 50% power from 586 ppm to 316 ppm. 
  • Raised first round of external funding from individual investors
  • The MFE01 Technology Demonstrator built which can produce 20kW, 6kg H2 per 24 hrs
  • The company move to new premises in Marrtree Business Park, Doncaster
