Chesterfield BioGas Food Waste Biogas for Grid Injection Contract in UKThe Thames Water site at Didcot was the first of its kind in the UK

A contract to supply and install upgrading equipment at the UK's latest food waste biogas to gird injection project in Stockport has been awarded to Chesterfield BioGas (CBG), a subsidiary of Sheffield based Pressure Technologies.

According to the company, in common with the first successful UK venture of its kind at Didcot, Oxfordshire, which opened in October 2010, at its hearts the Stockport facility will feature an upgrading unit designed and manufactured by CBG's partner, Greenlane Biogas of New Zealand.

The company said that the modular 'Kanuka' unit will take the raw biogas produced by Anaerobic Digestion (AD) of food waste collected from local hotels and restaurants and, using a water-wash process, upgrade it to 98% pure biomethane.

CBG's managing director, Stephen McCulloch, explained: "Our unit uses the proven Greenlane water-wash process which is successfully operating at over 60 sites around the world."
 
The unit is capable of processing up to 300 cubic metres of gas per hour and features a newly patented water-flooded screw compressor, according to CBG.
 
The facility, which the company expects to 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.

The company also claimed that while its first project at the Thames Water site at Didcot used raw biogas captured during the treatment of waste water, the use of gas derived from a food waste demonstrates the versatility of its system in coping with variable inputs from AD.

Once operational CBG said that the plant will generate enough renewable gas to supply the natural gas requirements for 1400 homes.
