Biogas – The Prince of Wales Opens Green CO? Capture Facility  


The CO2 produced at J V Energen’s Rainbarrow Farm AD plant is processed into a high-quality food and beverage grade product, where it is used for the carbonation of bottled and canned drinks, for distribution to pubs for on-site carbonation of beers, ciders and ales, and in horticulture to stimulate photosynthesis for the increased production of fruits and vegetables, as well as other various applications

The inaugural opening of this BioCarbonics joint venture green CO2 facility marks the launch of a pioneering model for the UK’s CO2 industry, where green CO2 is recovered from a network of renewable energy sources to ensure an improved continuity of supply, with no danger of a repeat of the industry-wide shortages experienced in 2018.

Championed by The Prince of Wales, Rainbarrow Farm AD plant was the UKs first commercial biomethane-to-grid plant, currently generating enough gas to reach 7,500 houses mid-winter and over 100,000 houses in summer, five times the population of Dorchester. Biogas produced at Rainbarrow Farm was first cleaned and injected as biomethane into the national gas network on October 11, 2012.

CO2 recovery at Rainbarrow Farm currently operates 12-14 hours per day, and will be moving to 24/7 production by mid-June and the facility will produce ±24 lorries per month when fully loaded.

Christopher Carson, BioCarbonics managing director said, “Most of the CO2 used in the UK comes from industrial fossil fuel processes with a historically unreliable continuity of supply. BioCarbonics is changing that by relying on multiple, smaller sources of green CO2, which is recovered from biomethane production, where clean, green  feedstocks are being converted into green gas for use in the national gas network to heat local homes and businesses.

“To safeguard against CO2 shortages, Rainbarrow Farm is one of two facilities in BioCarbonics’ growing network. The other facility, located in Herefordshire, has been active since June 2019. Together, these two facilities produce over 40 lorries per month of green liquid CO2.”

As well as the CO2 being utilized locally, the digestate by-product is used as an organic, peat free, nutrient soil enricher called  ‘BloominAmazingTM, which is bagged as a soil enricher for sale to over 350 garden centers, and helps local farmers significantly reduce reliance on artificial fertilizers.
