“…In addition to the high energy requirement, MEA is characterized by toxicity and degradation, so it cannot be considered a sustainable solvent given its effects on health and the environment, relevant topics for the construction of new industrial plants in general. For this reason, innovative solvents are being taken into account [6], and research on new species and their influence on the CO 2 removal process [7][8][9][10][11] is being carried out. Among the innovative solvents proposed in the last few years, amino acids can be considered environmentally friendly [12], in addition to being advantageous also for their energy requirements.…”

Alternative solvents based on aqueous solutions of amino acids have been recently developed as possible substitutes for Mono Ethanol Amine (MEA) for CO2 removal from flue gas streams. The potassium taurate solvent has the advantages of degradation resistance, low toxicity and low energy requirements for its regeneration. With any type of solvent, CO2 removal applied to a power production plant decreases the revenues obtained from selling electricity because of the energy requirements. Operating the CO2 removal section in flexible mode avoids significant effects on the profits of the power plant, while accomplishing environmental regulations. This work is the first journal paper focusing on the application in flexible mode of the potassium taurate system for treating a flue gas stream from a 500 MW coal-fired power plant. Techno-economic evaluations are performed to determine the best operating conditions considering the variation in the electricity demand and its price, and different values of carbon tax. In the summer period, with high electricity prices and demands, carbon tax values between 45 EUR/tCO2 and 60 EUR/tCO2 favor CO2 absorption in the flexible mode, without periods of full CO2 emissions during the day.
