Danish public utility company Amager Resource Center (ARC) inaugurated Monday a demonstration facility in Copenhagen which would capture carbon dioxide (CO2), then cool it and liquefy it before sending it to local vegetable growers.
According to the Danish District Heating Association (Dansk Fjernvarme), where ARC is member, the new facility at the waste-to-energy plant Amager Bakke has a daily capture capacity of up to 4 tons of CO2.
The collected CO2 will then be sent to Ostervang Sjaelland, a farm in the south of Denmark, where it will be used to help grow vegetables such as cucumbers, tomatoes, aubergines, and peppers.
Jannick Hauschildt Buhl, Sector Manager for carbon capture, utilization, and storage (CCUS) at Dansk Fjernvarme, called the event “a big day for green Denmark”.
“Carbon capture is an effective measure to reduce carbon emissions. But in addition to being a climate tool, capturing CO2 can also provide a resource that other sectors demand,” Buhl was quoted as saying by Danish news agency Ritzau.
Dansk Fjernvarme’s estimates show an annual capture capacity of up to 7 million tons of CO2 among its member companies. However, for this potential to be realized a new proposal for the CCUS sector must come from the Danish government.
According to Buhl, with many companies in the district heating sector across Denmark preparing carbon capture projects, it is necessary to have a better framework for, among other things, the transport and storage costs for the captured carbon.
ARC is responsible for all aspects of waste management in the Danish capital, including handling hazardous waste in an environmentally safe manner.
