The first-of-its-kind 'commercial-scale' carbon capture and storage (CCS) project that uses a post-combustion capture process recently opened in Saskatchewan, Canada. CCS equipment has been retrofitted onto the 140 MW third unit (commissioned in 1970) of local utility SaskPower's 800 MW coal-fired power station. The CCS retrofit has reduced the unit's capacity from 140 MW to 110 MW. It is designed to capture around 1mn t/y of carbon dioxide (CO2), reducing emissions that would otherwise have been produced by 90%. The captured CO2 will be injected into local oil fields to enhance oil recovery and into a saline aquifer 3 km underground for permanent storage.
