Coal powered much of the industrial revolution and continues to fuel economic growth in developing nations, including China and India.

The dark side of coal, however, is that it generates large quantities of the heat-trapping greenhouse gases, mostly carbon dioxide (CO2), that lead to climate change. This CO2 pollution is in addition to other emissions from coal burning that lead to thousands of premature deaths per day around the world.

It was once thought that the CO2 emissions from coal power stations could be controlled by burying CO2 underground economically. However, our recent analysis published in the journal Environmental Science & Technology shows that the concept of carbon capture and sequestration (CCS) will be significantly more expensive than previously thought because previous studies miscalculated the energy required. As such, it’s unlikely to provide an economically viable solution to CO2 pollution from coal-based power generators.
