Energy provider Ørsted announced today that it anticipates capturing and storing 400,000 tonnes of carbon per year from 2025, equivalent to removing around 200,000 cars from the road, based on plans to establish carbon capture at two of its Danish power stations.

The planned carbon capture will be established at the wood chip-fired Asnæs Power Station in Kalundborg on western Zealand and at the Avedøre Power Station’s straw-fired boiler in the Greater Copenhagen area. 

Ole Thomsen, Senior Vice President, Ørsted, said:

“With carbon capture at the Asnæs and Avedøre CHP plants, we’ll be able to capture 400,000 tonnes of carbon from 2025, which can be stored in the North Sea. This will contribute significantly to realising the politically decided climate target for 2025.” 

According to Ørsted, the two combined heat and power (CHP) plants are linked to the grid, the district heating system, and have their own harbours, enabling them to act as hubs for the handling and shipping of carbon and green fuels. They will not only serve as hubs for the capture and shipping of its own carbon but they will also for shipping carbon produced by other players.

The company is also in dialogue with energy company Kalundborg Refinery about the possibility of capturing carbon from the oil refinery for transport to Asnæs Power Station. The power station and the refinery will focus on carbon capture and storage, while the straw-fired boiler at Avedøre Power Station will capture and deliver some of the carbon to the initial phases of the Power-to-X project ‘Green Fuels for Denmark’, which aims to develop green fuels for the shipping and aviation industries.

 Niels Bech, Director for Business Development at Kalundborg Refinery, said:

“With this project we will be able to reduce our CO2-emissions significantly already in 2025, and we look forward to collaborating on CCS and thereby contributing to this technology being developed on a commercial scale for the benefit of Danish companies and the climate.”

Ørsted has also estimated that in the future, it will be possible to meet the need for sustainable biomass for the company’s CHP plants from straw and wood chips mainly from Denmark and neighboring countries, and it has decided to reduce the use of imported chips from 2030 and expects to mainly use Danish biomass as fuel for its boilers from the mid-2030s.

Until the wood chip-fired CHP plants reach the end of their service lives, Ørsted stated that it plans to continue to only use certified wood chips produced from sawdust and other wood residues from sustainably managed forests.

Thomsen said:

“Foreign wood pellets and wood chips are still a good and climate-friendly energy source when coming from certified sustainably managed forests. However, it makes a lot of sense to primarily use biomass from areas which are closer to home and thus get as close as possible to the supply chains to reduce the need for transport.”
