This chapter discusses recently announced large-scale CCS projects and federal and state legal framework for CCS in the United States, including both CCS regulation and incentives for CCS. This chapter also focuses on CCS concerns and challenges, including ownership and control of pore space onshore, the relative rights of private owners of pore space vis-à-vis each other, and the potentially conflicting rights of private pore-space owners and petroleum operators, and the need for regulatory unitization of pore-space reservoir or the use of eminent domain. Although briefly mentioned, largely excluded is “Utilization” (CCUS), such as using CO2 for enhanced oil recovery. More CCS will be needed than currently anticipated because the United States is not likely to move rapidly away from burning oil and natural gas to supply its energy needs and most existing coal-burning facilities are likely to operate until at least mid-century.
