    The Science Behind Clean Coal

    Carbon Capture and Storage (CCS) Mechanisms

    Carbon capture and storage (CCS) is a vital component of clean coal technology, aimed at capturing carbon dioxide emissions produced during the combustion of coal. This involves the separation of carbon dioxide from other gases before it is released into the atmosphere. The captured carbon dioxide is then transported to a storage site, where it is securely stored to prevent it from entering the atmosphere. One example of a successful CCS project is the Petra Nova facility in Texas, United States, which has been capturing and storing approximately 1.6 million tons of carbon dioxide annually since 2017. By implementing CCS mechanisms, coal-fired power plants can significantly reduce their greenhouse gas emissions, contributing to the global effort to mitigate climate change. This technology holds promise in making coal a more environmentally sustainable energy source, as it allows for the continued use of coal while minimizing its detrimental impact on the environment.
