Anaerobic digestion (AD) plant operators are being offered a new opportunity to benefit from an ‘innovative’ carbon capture and utilisation (CCU) model, proposed by BioCarbonics.
The UK-based green CO2 company has created a new channel to market for the biogas industry to enable CO2 captured from biogas facilities to be taken to market.
Green CO2 produced from biogas has a higher reliability of supply and is a more sustainable product than traditional CO2 derived from fossil fuels. In addition, capturing and utilising this CO2 contributes to the Renewable Heat Incentive sustainability criteria for AD plants and can boost the bottom line with long-term offtake agreements, said BioCarbonics.
“We work with biogas owners to capture and process their CO2 stream to produce a food and beverage quality liquid CO2, for use by local businesses,” said Christopher Carson, BioCarbonics’ managing director.
“Because we have a growing number of highly reliable plants operating around the clock, with a managed maintenance schedule, we are the only business that can offer continuity of supply to customers and no hidden surcharges.
“Our carbon capture model is totally unique in that we support plant owners from conceptual design through installation and start-up of their CO2 plants, and work with them to install and operate quality systems and equipment that ensures their product meets the food and beverage quality certification.
“We are actively seeking biogas owners who inject renewable methane [biomethane] into the gas grid to work with us and expand our sustainable supply model further.”
Hereford biogas plant owner, Nicholas Layton of STL Energy, has been working with BioCarbonics for several years and said there are many benefits to capturing CO2 from biogas installation, including preventing CO2 from being released into the atmosphere and supporting food and drinks producers.
“We didn’t have the expertise or knowledge required to enter into the CO2 business on our own,” said Layton,” and BioCarbonics gave us the support and training we needed to be able to do this successfully.”
STL Energy works with UK cider-maker Westons Cider, which supplies its biogas plant with apple pomace – a by-product from apple pressing. The company uses BioCarbonics’ CO2 to carbonate its drinks.
“Before working with STL Energy and BioCarbonics, we had CO2 supply issues,” said Maddy Spencer, purchasing manager at Westons Cider. “Now, from the circa 29,500 tonnes of cider apples we press annually, around 5,500 tonnes of pomace will be turned into CO2 and used to carbonate our products.”
