Answer:
B. it captures and stores the carbon dioxide
Explanation:
Greenhouse gas capture and storage technology emitted by coal-fired thermal power plants is already cost-effective, an association representing the European coal industry said.
Coal should have a future as a form of cheap fuel produced domestically by many countries, if the costs for carbon dioxide removal and other pollutant emissions are lower and the energy efficiency produced is improved.
Cost-efficient ways to remove acidic gases from thermal power plants and improving power generation efficiency are already a reality. If carbon capture costs can be reduced to about 20 euros ($ 25.61) a ton, clean burning of coal could be competitive.
The possibility of clean coal-fired technology has triggered a renewed interest in the commodity as a long-term energy source.
