ut exactly what is the technology?
The cleanest coal plant in North America is operated by Tampa Electric, in the middle of rural Florida. They call it clean because they don’t burn coal exactly – they mix it with water and oxygen and convert it into a gas.
According to company president John Ramil, gasifying coal allows the company to remove pollutants like sulphur, nitrogen and soot, which virtually eliminates acid rain.
“And you can do it much cleaner than with the conventional coal technology,” says Ramil.
That’s the good news. But here’s the problem.
“There is no such thing as clean coal,” says James Hansen, NASA’s expert on global warming, who says all coal plants, even TECO’s, still emit millions of tons of carbon dioxide – the most threatening greenhouse gas.
“There is no coal plant that captures the carbon dioxide and that’s the major long-term pollutant,” says Hansen.
But if carbon dioxide pollution is the problem with clean coal, many scientists believe there is a solution. They believe it’s possible to recover most of the carbon dioxide and store it underground.
The idea is called “capture and sequester,” and a global race is on to learn how it should be done. One Norwegian firm is storing tons of carbon dioxide in rock caves beneath the North Sea. America’s efforts to sequester carbon have stalled. The Department of Energy planned to fund a plant, but pulled all funding when the price grew too high.
Here is an idea whose time has come and long since gone. STOP IT!
