By Shardul SharmaNetherland-based technology company Bright Renewables announced on April 30 that it has secured the technical tender of Tekniska verken, a Swedish multi-utility energy company, for the supply of CO2 liquefaction technology.
The CO2 liquefaction system, to be installed at Tekniska's biogas plant Svensk Biogas in Linkoping, will purify and liquefy carbon dioxide (CO2) derived from the biogas production process to produce food-grade bioCO2. With an expected production capacity of 20,000 tonnes/year of food-grade quality bioCO2, the facility is slated for completion before the summer of 2025.
“CO2 liquefaction technology provides environmental and operational advantages. By recovering CO2 from biogas upgrading, it prevents atmospheric release, reducing greenhouse gas emissions. This technology also produces high-quality, food-grade bioCO2, a valuable resource for industries like food and beverages," Niraj Kunkulol, representative for the Scandinavian market at Bright Renewables, said.
The CO2 liquefaction system, boasting a capacity of 2,500 kg/hr of bioCO2, utilises natural refrigerant CO2 (R744) to purify and liquefy CO2 recovered from the biogas upgrading process. The system includes four 70 m3 storage tanks for liquid bioCO2 and a liquid CO2 analyser to certify food-grade quality, complementing existing clean technology plants and further reducing the carbon intensity (CI) score.
Tekniska made an investment decision in 2023 to build a facility to handle the biogenic carbon dioxide formed during the digestion of food waste, slaughterhouse waste, and more, which is then removed during biogas production.
Although CO2 emissions from biogas production are already biogenic today, meaning they do not contribute to any net emissions, recovering this carbon dioxide will have a positive climate effect, Bright said.
Last month, Bright installed and commissioned a biogas upgrading system in Groningen, Netherlands.
