Coal pollution mitigation - Wikipedia

Coal Pollution Mitigation, sometimes also known as Clean Coal, is a series of systems and technologies that seek to mitigate (reduce harmful or unpleasant chemicals) health and environmental impact of coal; in particular air pollution from coal-fired power stations, and from coal burnt by heavy industry. Clean Coal primarily focuses on removing sulfur dioxide (SO2) and nitrogen oxides (NOx), t

Carbon capture economics: Why $200 /tCO2 is the crucial figure

2023.3.20  Carbon capture and storage (CCS) costs are typically mis-quoted, failing to include full costs. In many cases, only ‘other’ operating costs are quoted, but these account for only ~10–15% of total costs from capture to injection. Full costs of CCS must cover the initial investment, financing, energy use (which leads to a significant loss of
