We Still Don't Know What Capturing CO2 From Power Plants Will Do
Capturing carbon dioxide from coal-burning power plants is promising for the environment, but then we have to figure out how to store it.By Evan Thomas | October 7, 2016
More and more carbon dioxide capture systems are starting up at coal-burning power plants. The world's largest is going online later this year in Texas. They can reduce as much as 90 percent of a plant's CO2 emissions — but what do we do with all of it?
One of the safest options is to pump the CO2 back into the ground. The research suggests that if you're careful about where you inject it, it will stay locked up for a thousand years without problems. Some CO2 is even pumped into oil wells to increase their output.
