CO 2 capture and storage (CCS) is a promising technology to mitigate CO 2 emission from fossil-fuelled power plants. The three existing CO 2 capturing technologies popularly used in the fossil-fuelled thermal plants are pre-combustion, oxy-fuel combustion, and post-combustion. Absorption, adsorption, membranes, chemical looping, and cryogenic are the prominent methods used in post-combustion technique. The cost reduction and energy savings are the two important challenges in CCS. Secondary power generation by using an organic Rankine cycle (ORC) from waste heat available from flue gas and CO 2 capturing units is an attractive option. A comprehensive review of research works carried out pertaining to the integration of ORC in power plants in the recent past is presented in this paper.
