CO 2 capture and disposal: The realism of large scale scenarios

Abstract

Several options for the capture and disposal of carbon dioxide from combustion of fossil fuels in power plants have been proposed and proven technically feasible. So far, most feasibility studies have been limited to single or a few power plants. A need was felt to assess the feasibility of reducing e.g. Europe's carbon dioxide emissions by, say, 30% through capture and disposal and/or utilisation. With background in available studies, the paper discusses the realism of disposal on a large scale in the ocean, in aquifer and in hydrocarbon reservoirs, as well as biofixation of carbon dioxide.
