National Grid has successfully commissioned its first commercial bio-gas project, connecting biomass operators Future Biogas to the gas network in Yorkshire.
Working with Biomass operators Future Biogas, National Grid have successfully commissioned the environmentally-friendly project to pump bio-methane, generated by locally-grown farming break-crops - including maize, grass and other biomass - into the gas network at Lindholme, near Doncaster.
Future Biogas Managing Director Philipp Lukas and National Grid’s Director of Network Strategy Jeremy Bending officially unveiled the £8 million, state-of-the-art plant at a ceremony on Tuesday (3 December). The state-of-the-art facility is the first bio-methane plant to be built and operated by Future Biogas. It processes 35,000 tonnes of feedstock, sourced from local farmers, every year.
The farm break-crops are fermented in an anaerobic digester to produce bio-gas, which consists of 60% methane and 40% carbon dioxide. The bio-gas is then processed by a clean-up technology to remove the carbon dioxide, resulting in a bio-methane gas. The volume and energy value of the bio-methane is then measured to ensure it meets the requirements of the gas network before being injected.
The plant can produce up to 12,000 cubic metres of gas per day - enough to heat 2,500 homes during peak demand in winter and some 40,000 homes during lower demand in the summer.
As a by-product, the process also produces a valuable organic fertiliser that will be used by the local farming community.
The Gas Distribution RIIO plan has a target to connect 80 bio-gas projects by 2020 and this is the first one.
