Can coal be burned cleanly?

Coal cleaning by ‘washing’ has been standard practice in developed countries for some time. It reduces emissions of ash and sulfur dioxide when the coal is burned. Electrostatic precipitators and fabric filters can remove 99% of the fly ash from the flue gases – these technologies are in widespread use.

Is there a such thing as clean coal?

According to the Sierra Club, “Despite the industry’s hype, there’s no such thing as ‘clean coal. ‘ But new technologies and policies can help reduce coal plants’ deadly emissions.” … Carbon dioxide from the coal gasification is shipped to Canada where it is injected into the ground to aid in oil recovery.

What is the cleanest burning form of coal?

How does clean coal technology work?

CCS technology sends the syngas to a shift reactor, where it encounters steam. That steam transforms the carbon monoxide that’s present into hydrogen and even more CO2. The CO2 is then captured from the gas stream, compressed, and dehydrated. That leaves it ready for transport and storage.
