The potential of Carbon Capture and Sequestration (CCS) technology as a tool for large-scale GHG emissions reductions and the role of intergovernmental organizations in crafting strategies for the financing and implementation of CCS-inclusive facilities. Taylor Blevin, Washington University in St. Louis Despite much advancement in carbon capture and sequestration (CCS) technologies, only one large-scale CCS facility is currently being operated worldwide, and only a few are being planned for the future. The largest barriers to the implementation of CCS technology are the high costs associated with it and the policies that affect the successful creation of these facilities. Many tools are available to policy makers in order to aid in the…show more content…
CO2, the most largely emitted greenhouse gas (GHG), is formed during the combustion process of hydrocarbon fuels. These include petroleum, natural gas, and, most significantly, coal (which makes up 40% of electricity generation-related fossil fuel consumption). Fossil fuel combustion accounts for approximately 84% of U.S. CO2 emissions (EPA), with 45% of these fossil-fuel combustion sources coming from electricity generation. Of these fossil fuels, coal has the highest carbon intensity, meaning that per unit mass of coal combusted, more CO2 is produced than for other fossil fuels. Additionally, coal often contains toxic impurities, most notably sulfur and mercury, which can be released as particles into the atmosphere along with CO2, NOx (a toxic, nitrogen-based gas that results from the incomplete combustion of a hydrocarbon in air), and CO (carbon monoxide, also resulting from incomplete fuel combustion). With the U.S. and other major emitters continuing to rely heavily on fossil fuels, it is clear that technology that addresses this dependence will be needed in order to meet emissions reduction targets. These technologies may include renewables (primarily wind and solar), increased energy efficiency, hydroelectric power generation, or carbon capture and sequestration technologies (CCS). While technological advances have continued and investment for both development and
