Calcium looping (CaL), or the regenerative calcium cycle (RCC), is a second-generation carbon capture technology. It is the most developed form of carbonate looping, where a metal (M) is reversibly reacted between its carbonate form (MCO 3) and its oxide form (MO) to separate carbon dioxide from other gases coming from either power generation or an industrial plant.
