Arjun Infrastructure Partners-backed Bigadan has launched Europe’s first fully operational biogenic carbon capture and offshore storage chain.
Danish renewable energy firm Bigadan captured CO2 at its Kalundborg Bioenergy facility and injected it into an offshore North Sea site, which Arjun said provided proof for a complete commercial model for capturing and storing carbon from organic waste.
Arjun said biogenic CO2 captured at the plant was permanently stored below the Danish North Sea through the INEOS Energy-operated Greensand facility.
Bigadan converts agricultural, household and industrial organic waste into renewable gas and nutrient-rich biofertiliser, providing waste treatment services while displacing fossil gas. The company holds a contract awarded by the Danish Energy Agency to capture and permanently store biogenic CO2.
Greensand is operated by INEOS alongside Harbour Energy and Nordsøfonden. Its first commercial phase can store up to 400,000 tonnes of CO2 annually, with potential capacity scaling to between four and eight million tonnes a year as the market develops.
Surinder Toor, managing partner at Arjun Infrastructure Partners, said: “Bigadan demonstrates what active, long-term infrastructure ownership can achieve. We entered the Danish biogas market early because we recognised the essential role biomethane could play in the energy transition and the potential to build a broader, integrated circular energy platform.
“Since investing in Bigadan, we have worked alongside management to scale and strengthen the business, encouraging the adoption of new capabilities such as carbon capture. The permanent storage of Bigadan’s CO2 beneath the North Sea is not a pilot project. It’s a fully operational, industrial-scale value chain, and evidence of the long-term, sustainable growth in the business we have delivered.”
Henrik Iversen, chief commercial officer at Bigadan, said: “Greensand marks a historic milestone for carbon capture and storage in Europe, and we are proud that Bigadan is contributing biogenic CO2 to it. Seeing the full value chain in operation – from capture and transport to permanent storage – demonstrates what can be achieved when industry, policymakers and technology work together.”
