The Ozone Hole

Clean Coal Technology. A major reason is that the impurities in coal like sulfur, nitrogen and many other trace elements can be almost entirely filtered out when coal is changed into a gas (a process called gasification). In fact, scientists have ways to remove 99.9% of the sulfur and small dirt particles from the coal gas.
