Carbon dioxide (CO2)
capture and sequestration (CCS) can significantly reduce emissions from large
stationary sources of CO2, which include coal- and natural-gas-fired power
plants, as well as certain industry types such as ethanol and natural gas
processing plants. CO2 can be captured using different methods. The main ones
are: post-combustion, pre-combustion and oxyfuel. Post-combustion technology
removes CO2 from the flue gases that result from burning fossil fuels.
Pre-combustion methods – carried out before burning the fossil fuel – involve
converting the fuel into a mixture of hydrogen and CO2. CO2 could also be used
to produce commercially marketable products. This is commonly known as carbon
capture storage and utilization (CCSU).
