What is ‘clean coal’?
The phrase refers to technologies that mitigate or avoid pollutants or CO2 emissions generated by converting coal to electric energy, says Jnos M. Ber, professor emeritus of chemical and fuel engineering. Low-cost, easily transportable and widely available, coal is the primary fuel for generating electricity in the US and many other countries.
Can coal be cleaned without burning it?
Researchers have discovered a stunning new process that takes the energy from coal without burning it — and removes virtually all of the pollution. The clean coal technique was developed by scientists at The Ohio State University, with just $5 million in funding from the federal government, and took 15 years to achieve.
Is coal bad for the environment?
That鈥檚 okay, because, neither does clean coal. Coal is the most carbon-rich fuel we have, and when it comes to the amount of climate-killing carbon dioxide it puts into the atmosphere, it鈥檚 filthy. Here鈥檚 how many pounds of CO2 our various fuels generate per million Btu units of energy produced, from greatest to least.
How much pollution is removed from the environment from coal?
The process removes 99 percent of the pollution from coal, which some scientists link to global warming. Coal-burning power plants produced about one-third of the nation鈥檚 carbon dioxide total in 2010, or about 2.3 billion metric tons, according to the Environmental Protection Agency (EPA).
