A key aspect of thermal power plants is their carbon intensity (CO₂ emitted per unit of energy generated, generally expressed as kg CO₂/MWh). Nowadays, the global average is around 500 kgCO₂/MWh, which must be reduced to 100 kgCO₂/MWh by the late 2030s to be consistent with a 2 °C climate pathway [36]. Even if combined cycle thermal power plants can be considered as low carbon alternatives in some scenarios, in the mid‐to‐long term, it might be required to further decarbonize the existing units by retrofitting them with CCS or by building novel designs with low CO₂ emissions. As demonstrated at commercial scale, post‐combustion CO₂ capture can significantly reduce the carbon intensity of thermal power plants [2]. Table 1.3 compares the carbon intensity of thermal power plants with and without CCS.
