Fossil Fuel Power

The objective of this strategy is to seek for the best approach for applying the concept of carbon capture, utilization and storage (CCUS) to the use of fossil fuel to generate power which will ensure that CO2 emissions are within the accepted target. Two approaches are considered in this program, namely, post combustion capture and pre-combustion capture.

Post-combustion CO2 capture refers to the capture of CO2 after the fossil fuel has been burned and the energy extracted. In post-combustion capture, chemical absorption with an aqueous amine solution is a technique proven to be effective in capturing CO2 from coal power stations. This amine-based post-combustion capture process for CO2 has been effectively used for decades as it can reach a desired target for capture of CO2 from relatively low-pressure streams, typically found in coal-derived flue gases. Furthermore, the ability to retrofit to the existing coal-fired power plants is really a key driver for the amine-based post-combustion capture technology as over 50% or more of electricity (e.g. Saskatchewan, Alberta, and the U.S.) being produced around the world is from this conventional coal combustion.

Pre-combustion capture is typically applied in Integrated Gasification Combined Cycle power plants. In this process, the fuel source is first gasified to produce a synthesis gas composed of carbon monoxide (CO) and hydrogen (H2). The CO by-product undergoes a water-gas shift reaction with water to produce CO2 and more H2. Other technologies for pre-combustion CO2 capture include steam reforming, dry reforming, autothermal reforming, etc. These processes inherently capture the CO2. Pre-combustion capture can be done using fossil fuels, biomass or a mix of the two.​​
