Proving the feasibility of producing hydrogen from a renewable source
Costain is working on a collaborative study to evaluate the feasibility of producing low carbon hydrogen from biogas at the Cardiff East Waste Water Treatment Works. The resulting hydrogen will provide low carbon energy as part of the nearby industrial operations of Princes Group.

Key Benefits
Creating a complete local hydrogen system
by combining a renewable hydrogen supply with a nearby industrial gas demand
Establishing a model for hydrogen supply and usage
as an enabler for wider hydrogen deployment.
Supporting the transition to cleaner fuels
to contribute to the UK’s net zero commitments
The feasibility study will also investigate the use of different blends of hydrogen with natural gas, enabling the transition to fuel switching and demonstrating system flexibility.
The programme is funded through the Department for Business, Energy and Industrial Strategy’s (BEIS) £1billion Net Zero Innovation Portfolio, which aims to accelerate the commercialisation of innovative clean energy technologies and processes through the 2020s and 2030s.

The H2Juice project has been awarded £372,931 of funding from the BEIS £26 million Industrial Hydrogen Accelerator Programme (Stream 2A), to demonstrate the feasibility of end-to-end industrial fuel switching to hydrogen. The study will take five months, with the possibility to awarded further funding in the subsequent Stream 2B, to conduct further engineering and a demonstrator.
This project builds on a similar study carried out with Welsh Water to evaluate the feasibility of converting waste gases from the sewage treatment process to produce fuel grade hydrogen, which could power local fleet vehicles.
Costain has been active for several years in the development of hydrogen schemes across the UK. This recent award is a great reflection of the hard work our energy teams have been involved in.
