CO2 emissions
The worldwide coal industry allocates extensive resources to researching and developing new technologies and ways of capturing greenhouse gases. Efficiencies are likely to be improved dramatically, and hence CO2 emissions reduced, through combustion and gasification techniques which are now at pilot and demonstration stages.
Clean coal is another avenue for improving fuel conversion efficiency. Investigations are underway into super-clean coal (35 percent ash) and ultraclean coal (less than 1 percent ash). Super-clean coal has the potential to enhance the combustion efficiency of conventional pulverized fuel power plants. Ultraclean coal will enable coal to be used in advanced power systems such as coal-fired gas turbines which, when operated in a combined cycle, have the potential to achieve much greater efficiencies.
