Before revision: Technology = Carbon capture Several different technological methods are available for carbon capture as demanded by the clean coal concept: Pre-combustion capture – This involves the gasification of a feedstock (such as coal) to form synthesis gas, which may be shifted to produce an and -rich gas mixture, from which the can be efficiently captured and separated, transported, and ultimately sequestered, This technology is usually associated with Integrated Gasification Combined Cycle process configurations.
