Things We Can Do To Save The Environment - Issue No. 12 - Capture the Carbon

Carbon emissions have been brought up before, from Turning Food Into Fuel to Paying the Carbon Tax, but what if we could take one of the world's dirtiest fuels and sequestrate it?

Giving credit to TIME,  I'd like to thank them for showing us the many ways we can help save the environment.  Just one person can make a difference, and it starts with YOU!

12. Capture the Carbon

Coal is one of the dirtiest fuels around and a major source of the world's carbon dioxide emissions. It's also hard to live without. In the U.S., half the electricity generated comes from coal. What if coal-fired plants stopped spewing their carbon dioxide fumes into the air and instead sequestered them—pumped them deep into the ground for storage?

Carbon sequestration is (despite its name) a simple-sounding idea that's exciting scientists, governments and energy companies as a way to cut emissions without disrupting energy supplies. One coal-fired plant in Denmark is working to trap carbon flue gases and store them in four spots, including an unused oil field off the coast of Spain. A Swedish utility is testing new ways to extract pure carbon dioxide from coal emissions in a lignite plant in eastern Germany. In the biggest test so far, a Norwegian energy firm is injecting 1 million tons of CO2 a year from the Sleipner gas field into a saline aquifer under the North Sea. "All the basic technology is already here," says Howard Herzog, an energy expert at the Massachusetts Institute of Technology. A report by the International Energy Agency (IEA) in Paris says sequestration would be second only to energy-saving measures in reducing CO2 emissions, far ahead of better-known efforts like renewable energy.

There are two major obstacles. The first is cost, which the IEA estimates to be as much as $50 for each ton of carbon captured. Those costs may drop if the technology is successful and utilities are given incentives not to spew out carbon dioxide. The other obstacle is a lack of detailed scientific knowledge. The pilot projects are going well, but M.I.T.'s Herzog says, "We'd like to see more large-scale demonstrations worldwide to really bolster confidence." In the meantime, watch for sequestration to move quickly up the energy agenda.
