Chesterfield BioGas (CBG) has been awarded a further contract to supply its biogas upgrading technology for a plant in Scotland.
Chesterfield Bio-Gas wins third Scottish biomethane-to-grid contract

The plant is located at St. Boswells, near Melrose in the Scottish borders. It will process raw biogas produced by anaerobic digestion of energy crops and some vegetable wastes. The biogas will then be cleaned to more than 98 percent purity by using CBG’s Greenlane upgrading plant. Over 3 million cubic metres of gas per year is expected to be injected into the grid once the plant starts operating in Summer 2015.

CBG’s contract is with Iona Capital, in collaboration with project partners Scotia Gas Networks (SGN) on behalf of site owners and project developers Charlesfield First LLP. CBG and Iona are already working together on a similar gas-to-grid project which is nearing completion on a farm site at Coupar Angus in Perthshire. Both plants will be managed by Biogas Power Ltd who advised on the adoption of the water-wash method of biogas upgrading. Feedstocks for the anaerobic digester (AD) will be sourced under a long-term arrangement with a number of farms in the vicinity.

“I am a strong advocate of water-wash technology and we are very pleased to be working with CBG and Iona a second project” said Ed Cattigan, Managing Director of Biogas Power.

CBG’s contract for the St Boswells site includes a 5-year enhanced aftercare package providing comprehensive 24/7 cover for the upgrader. This includes remote monitoring and management of the plant’s performance, further strengthened by having scheduled monthly site visits by a dedicated UK-based CBG service team.

The ‘Rimu’ unit being installed on Charlesfield’s estate at St. Boswells is a mid-capacity model in the new-generation of Greenlane water-wash upgraders. The system is proven on over 80 operational sites around the world, but this particular model will be the first in its throughput volume range to be installed in the UK. It has the flexibility to efficiently process between 250 and 800 cubic metres of biogas per hour.
