Calculating CO₂ avoidance costs of Carbon Capture and Storage from industry

This work discusses methods for calculating the CO₂ avoidance cost for Carbon Capture and
Storage from the non-power generation industry. Unlike the power generation sector, three
calculation methods are often used to evaluate the CO₂ avoidance cost in the case of CCS
from industrial sources. However, each of these methods relies on different assumptions of
which potential users are not always aware. The links between these three methods are
here presented and verified over an illustrative case to highlight the conditions that are
required to ensure their reliable use, as well as their associated shortcomings. Finally, the
basis to ensure the selection of the CO₂ avoidance cost calculation method that is both valid
and most efficient for cases considered by potential users are presented.
