Method and system to capture CO2 in flue gases emitted intermittently
[EN] The disclosure relates to a method to capture CO2 from the flue gases emitted intermittently from a power plant burning a synthetic fuel in power-to-fuel-to-power systems. The method comprises arranging a reservoir of Ca(OH)2 to feed a flow of such solids to a countercurrent carbonator located in the flue gas path of the power plant, separating the resulting carbonated solids from the CO2 depleted-gas, storing the carbonated solids in a reservoir of CaCO3 while the power plant is operating, calcining a steady flow of carbonated solids to produce CaO solids and CO2 when the power plant is not operating, hydrating the resulting CaO solids with water to replenish the reservoir of Ca(OH)2 and feeding the CO2 to the power-to-fuel system to manufacture and store the synthetic fuel burned when the power plant is operating.
