Why Hydrogen?


It's versatile

Hydrogen is one of the world's most versatile energy carriers, energy stores, and industrial feedstocks. Found in methane and propane as well as water, where it can be extracted as a gas by electrolysis. It is key to the decarbonisation of our planet.


It's clean

When supplied by renewable electricity for production, hydrogen becomes a clean source of energy. Producing green hydrogen only emits oxygen and heat as it's by-products which can be harvested for further use.


It's the future

We need to replace the use of fossil fuels. Green hydrogen will heat and power our homes and businesses. It will fuel transport, ancillary vehicles, and equipment and feed into many industrial processes.

About CPH2

Being passionate about hydrogen as clean energy for the future, we wanted to find an to PEM electrolysers as these had barriers to adoption. We realised that the cleanest way to produce hydrogen was by membrane-free water electrolysis, and in doing so, it would be a less expensive and more robust technology.

Dr. Nigel Williamson and Joe Scott established CPH2 (Ireland) in 2012 with the ambition to help clean up the environment for our children and future generations. Entering the green technology sector; a high growth and profitable market, they developed a Membrane-Free Electrolyser™ to produce hydrogen faster, more reliably, and more cost-effectively than other electrolysers.
