Concern over the potential effects of greenhouse gases such as carbon dioxide (CO₂) on global climate has triggered research about ways to mitigate the release of these gases to the atmosphere. A project to study the engineering feasibility and costs of sequestering CO₂ in deep, saline reservoirs was completed as part of a U.S. Department of Energy (DOE) program supporting research on novel technologies to mitigate greenhouse gas emissions. Study activities included a review of the status of existing technologies that could be used for CO₂ sequestration, development of a preliminary engineering concept for accomplishing the required operations, and estimation of costs for sequestration systems. The primary components of the CO₂ sequestration system considered are: · Capture of the CO₂ from the flue gas · Preparation of the CO₂ for transportation (compression and drying) · Transportation of the CO₂ through a pipeline · Injection of the CO₂ into a suitable aquifer. Costs are estimated for sequestration of CO₂ from two types of power plants: pulverized coal with flue gas desulphurization (PC/FGD) and integrated coal gasification combined cycle (IGCC). The sensitivity of cost to a variety of transportation and injection scenarios was also studied. The results show that the engineering aspects of the major components of CO₂ capture and geologic storage are well understood through experience in related industries such as CO₂ production, pipeline transport, and subsurface injection of liquids and gases for gas storage, waste disposal, and enhanced oil recovery. Capital costs for capture and compression and the operational cost for compression are the largest cost components.
