Optimisation economics for CO2 capture and storage in Central Queensland (Australia)

摘要: Abstract Studies of the cost carbon capture and storage (CCS) frequently make a single set assumptions about characteristics source CO2and injection site (the sink). However, in practice, design whole CCS system will require optimisation involving selecting appropriate pipeline sizes, route, number, type placing wells. This study reports possible project Australia examines effects different parameters designing system. The area surrounding Gladstone, Rockhampton, Stanwell Callide (“Gladrock”) Central Queensland emits over 40.5 million tonnes (Mt) dioxide (CO2) from fixed sources every year. least solutions for technologies Gladstone Rockhampton area. optimises transporting CO2from power stations Gladrock region injecting CO2in Aramac coal measures. Basic engineering results together with capital operating costs individual sets equipment are assessed. Large compressors several hundred megawatts required at each to raise CO2to supercritical conditions transport storage.
