Carbon capture provider Aker Carbon Capture has been awarded an integration feasibility study by Söderenergi, which is one of the biggest district heating producers in Sweden. The study will assess implementing CO2 capture at Igelstaverket in the city of Södertälje. Situated at about 30 km from Stockholm, Igelstaverket is Sweden’s second-largest biomass combined heat and power plant. The planned capture capacity will be around 500,000 metric tons of biogenic carbon annually.
Jon Christopher Knudsen, Chief Commercial Officer at Aker Carbon Capture, said that bioenergy with CO2 capture and storage (BECCS) has been identified as playing a crucial role in Sweden’s net-zero goals by 2045. Given Söderenergi’s private harbor and convenient connection to the Baltic Sea, the Igelstaverket project opens up possibilities for shipping to CO2 storage locations currently being developed in Norway and Denmark, he also said.
The feasibility study will evaluate optimal carbon capture, conditioning, liquefaction, and temporary storage facility. The study will also look into heat recovery potential and heat integration solutions to reduce the total heating and cooling demands related to carbon capturing and conditioning and allow for returning excess heat to the district heating network. Currently, Söderenergi produces heating for about 120,000 households and for offices and industries.
Aker Carbon Capture is currently delivering a Just Catch unit with an annual capacity of 100,000 metric tons of carbon at Twence’s waste-to-energy site in the Netherlands. This June, the company will also start delivering five Just Catch units to Ørsted’s bioenergy sites in Denmark. The combined capacity of the five CO2 capture plants is 500,000 metric tons of carbon annually.
The Just Catch units are standardized carbon capture plants for the delivery of pure CO2 for various applications.
