The first initiative to produce fuel cell grade hydrogen using wastewater in Great Britain will begin with a project in Cambridgeshire this summer. Element 2, the UK’s leading hydrogen infrastructure business, will purchase hydrogen produced by a new electrolyser at Anglian Water’s Milton Road, Cambridge water recycling site and supply it to hydrogen vehicles.

Producing green hydrogen while reducing emissions in the water treatment process

The hydrogen will be produced as part of the innovative Triple Carbon Reduction Project – delivered via a partnership funded through Ofwat’s Water Breakthrough Challenge. The project aims to reduce carbon emissions during the water recycling process. The integrated electrolyser system is being introduced as part of the water pre-treatment process to generate green hydrogen and oxygen.

It’s anticipated that up to 91kg of fuel cell grade hydrogen, suitable for use with hydrogen vehicles, will be generated each day when operating at 100% runtime from July 2023.

Supplying green hydrogen to hydrogen vehicle manufacturers

Element 2 will provide cutting-edge storage for the hydrogen produced at Anglian Water’s Cambridgeshire site and transport it to its network of hydrogen refuelling stations around the UK. From there, the hydrogen will be used to fuel Element 2’s customer base of hydrogen fleet owners and operators, as well as to support hydrogen engine development and for trials of new fuel cell vehicles arriving on UK roads. Vehicles that will benefit from the hydrogen include trucks, vans and buses.

Safe and environmentally friendly hydrogen production

Element 2 will work in partnership with Anglian Water to ensure the design, installation and commissioning of the integrated electrolyser system and its location are suitable for the safe and efficient transfer, storage and collection of hydrogen. Element 2 will also collaborate with Anglian Water to quantify the environmental benefits of the trial.
