Comment on 'Reassessing the Efficiency Penalty from Carbon Capture in Coal-Fired Power Plants'

摘要

This letter is in response to the article by Supekar and Skerlos entitled, "Reassessing the Efficiency Penalty from Carbon Capture in Coal-Fired Power Plants". We find the article seriously flawed because, (1) the results presented are contradicted by actual practice and experience, and (2) the analysis is based on outdated data and unrealistic design assumptions that are not at all consistent with more recent cost studies or the design and operation of real CCS projects. The article also appears to incorrectly compare the cost of fossil fuel electricity with that of intermittent renewables by ignoring the added costs and emissions incurred by wind and solar systems to provide equivalent baseload service.
