This article provides more of an overview of carbon capture systems and possible interactions on air quality, but is less focused on dispersion effects and more on general issues that need to be considered.
One of the key challenges for any new technology is overcoming the lack of guidance and in some cases regulation, and it is often not clear how existing guidance and requirements may apply to new technology. Some of these issues are directly applicable to CCS. For example it is not clear whether emission limit values apply before or after the CCS process for a thermal combustion process. This is an important distinction since the CCS process removes considerable volume from the flue gas, but only a small amount of pollutants other the CO2, which means the overall concentration of other pollutants such as NOx could increase. This may affect which abatement technology would be selected.
