Kalundborg Bioenergi Carbon Capture Project

Bigadan is developing a biogenic carbon capture and storage (BECCS) project at its Kalundborg Bioenergy facility in Denmark, where organic waste streams from Novo Nordisk and Novonesis are converted into biomethane. Beginning in 2026, the facility will capture, purify, and liquefy the biogenic CO₂ that is separated during the biogas upgrading process rather than venting it to the atmosphere. The plant produces roughly 28–30 million Nm³ of biomethane annually, and the captured CO₂ is expected to be permanently stored offshore in the North Sea through the Greensand Future project operated by a consortium including INEOS Energy. The carbon capture system includes a large-scale CO₂ liquefaction facility supplied by Kanadevia Inova, designed with dual liquefaction trains capable of processing more than 4,000 kg of CO₂ per hour. The project received support under Denmark’s NECCS (Negative Emissions CCS) funding program, which supports the capture and permanent storage of biogenic CO₂ to generate carbon-negative emissions. Liquefied CO₂ from the site will be transported to Esbjerg for shipment and injection into depleted offshore oil and gas reservoirs beneath the Danish North Sea, helping establish Denmark’s emerging CCS infrastructure and negative emissions market.
