is a problem,
so why not collect it as it leaves coal plants, compress it and
use it for something else? it appears that this procedure is about to happen, the gas is collected by
spritzing the plant's exhaust with a chemical solvent, the purified carbon
dioxide then gets compressed into a liquid and piped 80 miles away to an active
oil field, once there, the carbon dioxide gets piped underground, where it
helps force oil to the surface, this is going to happen in what will eventually
be the world's largest carbon capture facility near Houston, Texas,
the Petra
Nova system captures carbon dioxide to help people mine ever more oil, which of
course creates its own emissions once it's burned to make electricity, but the
hope is that the sequestered carbon dioxide will not find its way up to
the surface of the Earth and back into the atmosphere, the project is expected
to capture 1.6 million tons of carbon dioxide annually, which equals about 40
percent of one of the coal plant's units, the plant, called the W. A.
Parish Plant, has four units, besides Petra Nova, a handful of similar projects
are underway around the world, Yale
Environment 360 reports there
are pending projects in Saskatchewan, Mississippi and Illinois, plus 34
"proposed or operating" projects outside of North America, the
Saskatchewan system is supposed to go on line later this year, Petra Nova is
slated to open in 2016, hopefully the cost will be off set as Petra Nova's
engineers hope the system will eventually pay for itself because it's linked to
increased oil production, let hope it all goes well.
