The Prince of Wales opens pioneering green CO₂ capture facility

The Prince of Wales opened J V Energen’s new CO2 capture facility near the Duchy of Cornwall’s Poundbury development in Dorset where green CO₂ is supplied to their new joint venture business BioCarbonics.
The gas is captured from a full-scale anaerobic digestion (AD) and biomethane-to-grid plant, to produce a clean, sustainably sourced product for use by local businesses.
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.
This is 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.
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 11 October 2012.
CO2 recovery at Rainbarrow Farm currently operates 12-14 hours per day, and will be moving to 24/7 production by mid-June.
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.”
