Reserves and resources for CO2 storage in Europe: the CO2StoP project

The challenge of climate change demands reduction in global CO2 emissions. In order to fight global warming many countries are looking at technological solutions to keep the release of CO2 into the atmosphere under control. One of the most promising techniques is carbon dioxide capture and storage (CCS), also known as CO2 geological storage. CCS can reduce the world’s total CO2 release by about one quarter by 2050 (IEA 2008, 2013; Metz et al. 2005). CCS usually involves a series of steps: (1) separation of the CO2 from the gases produced by large power plants or other point sources, (2) compression of the CO2 into supercritical fluid, (3) transportation to a storage location and (4) injecting it into deep underground geological formations.
