Amager Bakke (ARC)


The Amager Resource Center is Copenhagen’s famous waste-to-energy facility. Motivated by the ambition of the Municipality to become CO2-neutral by 2025, ARC started investigating the possibility of applying carbon capture and storage/utilisation technology (CCS/CCU) to their waste-to-energy plant in 2019.

Waste-to-energy plants are particularly suited for CCS/CCU. This is because they have many pathways to recuperate heat streams needed to operate and minimize the energy consumption in relation to carbon capture. The principle behind is to capture the CO2 from the smoke leaving the incinerators by spraying the smoke with a liquid that binds the CO2. Such a process enables the capture of CO2 and have CO2-free smoke leaving the chimney. The CO2 is then stored, but the long-term plan is to use it as a fuel replacing oil.

In February 2020, a study conducted and completed by ARC showed it is technically and economically feasible to couple CCS/CCU technology to its plant. This means that the 480,000 tons of CO2 emitted every year by ARC can be captured by the facility itself in a cost-effective way. This means CO2 reductions at the lowest possible cost to the citizens.

“Despite all the efforts towards a green transition, there will continue to be waste. This is why we are looking for solutions that can reduce our CO2 emissions.”

The ground-breaking ambition of this project, in cooperation with DTU-CERE, Rambøll, and Union Engineering, tis o demonstrate that carbon capture at ARC can be done at net-zero energy consumption. In other words, the project aims to optimize the energy consumption of every step of the CCS process to achieve the cheapest energy consumption CCS process.

1st Mile’s work with ARC

The first step to implement the project is the demonstration of the technical and economic feasibility of the Carbon Capture technology.  This means that it is achievable at an acceptable cost both for waste producers and heat consumers (the citizens).

This is why the EUDP granted DKK 30 mio to ARC after collaborating with 1st Mile. It has a key role for demonstrating the feasibility of cost-effective carbon capture on waste-to-energy plants. Moreover, it marks a critical milestone and decision point for full-scale deployment of decarbonization of the waste-to-energy industry globally. The final outcome of the project will be a decision base for ARC to decide upon an investment in a full-size Carbon Capture plant to capture all of the 480,000 tons of CO2 emitted by ARC every year.

“It’s fantastic. It is the first of its kind in Denmark, and the prospects are enormous. It points in the right direction. ARC’s ambition is to manage waste in a completely carbon neutral way. The project is a serious and significant contribution to realizing the vision of the world’s first carbon neutral capital.”
