What is clean coal technology? | HowStuffWorks

Another process, oxy-fuel combustion, burns the fuel in pure or enriched oxygen to create a flue gas composed primarily of CO2 and water -- this ­sidesteps the energy-intensive process of separating the CO2 from other flue gasses. A third technology, pre-combustion capture, removes the CO2 before it's burned as a part of a gasification process.
