FLI Energy begins construction of Euston Biomethane-to-Grid AD project

Once operating to full capacity, the anaerobic digestion plant will generate 10 million cubic meters of biogas.

Under the £9 million contract, FLI Energy will provide full EPC wrapped project delivery, including the design, construction and commissioning of the plant, as well as a five-year maintenance and process analysis support contract. FLI Energy signed the EPC contract on February 2014, from project developers Strutt and Parker Farms Ltd, one of the largest farming businesses in the UK, and SS Agripower.

Following on from several successful UK biogas projects, FLI Energy will again be collaborating closely with HoSt B.V. from Holland, who have been FLI Energy’s longstanding anaerobic digestion technology partner, to deliver the Euston project. HoSt B.V. boasts extensive experience in mixed feedstock anaerobic digestion process design.

FLI Energy’s turnkey contract scope includes detailed civil and process design, ground-works, site secondary containment bunding, drainage, silage clamp, digestate storage, anaerobic digestion plant technology, CHP, biogas upgrading, propane addition, and biomethane network entry. The biogas upgrading technology will be supplied to FLI Energy by the Dutch company Pentair Haffmans.

The main energy export of the plant is renewable bio-methane. When commissioned, the project will generate 10 million cubic meters of biogas, which after upgrading on site will be exported to the gas grid as renewable bio-methane. The renewable electricity and heat generated at the facility will be largely consumed on site to power the plant itself.

To date, the biogas plants delivered by FLI have a combined electrical output of 52,000 MWh each year – enough to power more than 6,500 homes, and potentially diverting nearly 100,000 tonnes of biodegradable waste from landfill. 

Declan McGrath, FLI Energy’s managing director, stated: “Our focus has recently been on the decarbonisation of the gas grid, and this year, the completion of the Euston project together with other projects underway will contribute more than 15 million cubic meters of gas to the grid – the electrical equivalent of powering over 8,000 homes.”
