Is There Enough Space For Carbon Sequestration?
April 27, 2010
One ever-popular idea for reducing greenhouse-gas emissions from coal plants is to capture the CO2 at the smokestack and bury it underground. Up until now, the biggest hurdle here has always been cost: While burning coal is relatively cheap (that is, if you ignore the pollution, the coal ash spills, and the devastation wrought by mountaintop mining…), sequestering CO2 can be pretty pricey—pricier than efficiency and even a lot of renewable power options. But now it turns out there may be another problem.
