Question

What specific term is used to describe the total economic efficiency of a project, calculated as the net cost of the capture system divided by the total mass of CO2 prevented from entering the atmosphere?

Accepted Answer

The specific term used to describe this metric is the cost of carbon capture, often expressed as the cost per tonne of CO2 avoided. This value is calculated by taking the net cost of the capture system—which includes both the capital investment to build the technology and the ongoing operational expenses—and dividing it by the total mass of carbon dioxide that is prevented from entering the atmosphere due to that system. The term net cost refers to the total financial outlay minus any value recovered from the process, such as selling captured CO2 for industrial use. By calculating the cost per tonne of CO2 avoided, analysts can compare the economic efficiency of different carbon reduction projects, such as comparing a chemical solvent absorption plant at a power station against a direct air capture facility. A lower cost per tonne indicates higher economic efficiency, meaning the project achieves a greater climate benefit for every dollar spent.
