This project represents a significant milestone, being the first large-scale carbon capture project in Denmark and marks the beginning of a new phase for carbon capture and storage in the country.
Ørsted has started construction of two carbon capture (CCS) facilities designed to collect and store carbon emissions generated by the wood chip-fed Asnaes power station in Kalundborg and the straw-fed unit of the Advedøre power station located in Greater Copenhagen.
Ørsted has identified the straw-burning biomass unit at the Advedore power plant as the most suitable source of sustainable CO 2 . The carbon capture project, which was awarded a 20-year contract by the Danish Energy Agency in May 2023, aims to capture 430,000 tonnes of CO annually.2 biogenic from the two combined heat and power plants from early 2026.
This initiative will significantly contribute to Denmark’s climate goals for 2025 and 2030.
Ole Thomsen, senior vice president and head of Ørsted’s bioenergy business, says: “ We are proud to start construction of Denmark’s first large-scale carbon capture project .”
Ørsted Kalundborg CO 2 Hub: the carbon capture project
The “Ørsted Kalundborg CO 2 Hub” project aims to capture and store 430,000 tonnes of CO 2 annually starting in early 2026, which is equivalent to the annual carbon emissions of approximately 200,000 gasoline cars. Ørsted plans to capture 150,000 tonnes of biogenic CO 2 annually from the straw-fed unit at the Avedøre power station.
Initially, the CO 2 will be trucked to the Asnæs power station until a shared pipeline infrastructure is established across Zealand. Avedøre Power Station’s straw-fuelled unit converts local straw into electricity and district heating, using straw as a by-product of agriculture.
It should be noted that the company plans to capture 280,000 tons of CO2 biogenic annually from the wood chip fueled unit at the Asnæs power station, which will also act as a CO center2, handling and shipping biogenic carbon from the Avedøre and Asnæs combined heat and power plants to the Northern Lights storage reservoir located in the Norwegian part of the North Sea.
The wood chip unit at the Asnæs power station transforms wood chips, mainly from the Baltic countries, into electricity, district heating and process steam for local industry. These wood chips are obtained from sustainably managed production forests and are composed of surplus wood from sawmills, as well as waste from pruning or twisted trees.
