CCS Economic Benchmarking calculation tool

This Excel tool implements a simplified method to estimate the cost of CO₂ avoided for a power plant with a novel CO₂ capture system based on only a limited number of fundamental input parameters used to establish basic mass and energy flows for the plant. The complete methodology is presented in the paper:

The cost calculation method follows a sequential approach, estimating first the cost and efficiency penalty impacts of those elements of the plant that are standard and well characterized. Then, the tool estimates the cost gap allowed for the novel elements to break even against a benchmark plant. This method allows the model to estimate: (i) the maximum cost reduction potential that a novel CO₂ capture technology can achieve with respect to a benchmark technology, and (ii) target breakeven costs for technology developers in the form of combinations of CAPEX and OPEX for a novel capture technology needed to make the technology competitive with the benchmark system.
