So much soot belched from the old power plant here that Mike Zeleny would personally warn the neighbors.
“If the wind was blowing in a certain direction,” Mr. Zeleny said, “we’d call Mrs. Robinson down the street and tell her not to put out her laundry.”
That coal plant is long gone, replaced by a much larger and cleaner one along the vast Saskatchewan prairie. Sooty shirts and socks are a thing of the past.
But as with even the most modern coal plants, its smokestacks still emit enormous amounts of carbon dioxide, the invisible heat-trapping gas that is the main contributor to global warming. So this fall, a gleaming new maze of pipes and tanks — topped with what looks like the Tin Man’s hat — will suck up 90 percent of the carbon dioxide from one of the boilers so it can be shipped out for burial, deep underground.
If there is any hope of staving off the worst effects of climate change, many scientists say, this must be part of it — capturing the carbon that spews from power plants and locking it away, permanently. For now, they contend, the world is too dependent on fossil fuels to do anything less.
If all goes as planned, the effort in Saskatchewan will be the first major one of its kind at a power plant, the equivalent of taking about 250,000 cars off the road. And at least in theory, that carbon dioxide will be kept out of the atmosphere forever.
