Chesterfield BioGas Ltd (CBG) has today secured a contract to supply and install upgrading equipment for the UK’s latest project to use gas from renewable waste resources and inject it directly into the national gas grid.

The contract win is seen as a good deal for the company, a subsidiary of Pressure Technologies plc (PT).

The system in Stockport, like the first successful UK venture of its kind in Didcot which opened in October 2010, will feature, at its heart, an upgrading unit designed and manufactured by CBG’s partner, Greenlane® Biogas of New Zealand.

The modular ‘Kanuka’ unit will take the raw biogas produced by anaerobic digestion of food waste from local hotels and restaurants and, using the proven water-wash process, upgrade it to 98% pure biomethane. The unit is capable of processing up to 300 cubic metres of gas per hour and features a newly patented water-flooded screw compressor.

“This is a considerable vote of confidence in our technology and performance. Our unit uses the proven Greenlane® water-wash process which is successfully operating at over 60 sites around the world”

Stephen McCulloch, Managing Director of CBG

The facility, which will open in Autumn 2012, will be operated by Fairfield Bio Energy - a partnership between green energy firm Bio Group Ltd and Centrica, the owners of British Gas. It will generate enough renewable gas to supply the natural gas requirements for 1,400 homes.

CBG’s contract, including ancillaries and remote monitoring services, is worth approximately £1m.

CBG’s Managing Director, Stephen McCulloch, said of the contract win, “This is a considerable vote of confidence in our technology and performance. Our unit uses the proven Greenlane® water-wash process which is successfully operating at over 60 sites around the world.”

“CBG established a firm working relationship with Centrica in the course of our work at the first UK project, which opened in Autumn 2010, and we are delighted to be their preferred supplier once again.”

Describing the success of the first system in Stockport, he added, “Our first project at the Thames Water site at Didcot used raw biogas captured during the treatment of waste water. The fact that the new Stockport site will use gas derived from a completely different waste material is a significant testament to our upgrading system and its versatility in coping with variable inputs from the anaerobic digestion process.”

Group Chief Executive, John Hayward, was just as enthusiastic and said in a company statement, “Chesterfield BioGas is firmly established as the market leader in upgrade technology in the UK. As the only UK-based supplier and installer of this type of technology, we have the experience and expertise to manage projects to the exacting engineering and health and safety standards demanded by large utility companies and gas grid operators. We look forward to further progress in this market over coming months.”
