The capture and storage of CO₂ is much less expensive when it is included in the design of a power plant from the outset. A benchmarking study by Circular Energy shows that the costs for CCS for an integrated design amount to only €6/ton. That is only 5% of the calculated costs of the former ROAD-project and 10% of the costs that EBN refers to. The costs are even lower than the current market price for CO₂ emission rights.
The Rotterdam Storage and Capture Demonstration project (ROAD) has been cancelled. This project was based on the "end of pipe" principle: CO₂ is captured from a currently existing power station, transported to a location at sea and compressed for injection. Substantial investment with no additional income. The costs were estimated at more than €120/ton.
Circular Energy integrates the CO₂ capture and storage in the design of the power plant. This has several advantages:
- The capture process maximizes the use of the residual heat from the electricity generation process
- Because we are located right above our gas field, into which we inject the CO₂ we do not need a transport pipeline to store it.
The effect of these factors is spectacular. We collect CO₂ and store it for about €6/ton. This is clearly lower than comparable CCS projects and lower than the current market price for CO₂ emission rights.
