Coal pollution mitigation - Wikipedia
Whether carbon capture and storage technology is adopted worldwide will "..pend less on science than on economics. Cleaning coal is very expensive." Conversion of a conventional coal-fired power plant is done by injecting the CO2 into ammonium carbonate after which it is then transported and deposited underground (preferably in soil beneath the sea). This injection process however is by far the most expensive. Besides the cost of the e
