Carbon sequestration

Dec 10, 2007--Scientists from Columbia University’s Lamont-Doherty Earth Observatory will report this week on vital topics including new evidence of the effects of climate change; technologies to confront it; studies of eastern U.S. earthquake risk; and previously unseen inner workings of the deep polar ice caps.  The reports will be presented at the fall 2007 American Geophysical Union (AGU), the largest earth-sciences gathering in the world, Dec. 10-14 in San Francisco.

Drilling, experiments, target huge formations off West Coast

Palisades, N.Y., July 14, 2008—A group of scientists has used deep ocean-floor drilling and experiments to show that volcanic rocks off the  West Coast and elsewhere might be used to securely imprison huge amounts of globe-warming carbon dioxide captured from power plants or other sources. In particular, they say that natural chemical reactions under 78,000 square kilometers (30,000 square miles) of ocean floor off California, Oregon, Washington and British Columbia could lock in as much as 150 years of U.S. CO2 production

6,000 Square Miles in U.S. Might Turn Emissions to Harmless Solids 

To slow global warming, scientists are exploring ways to pull carbon dioxide from the air and safely lock it away.

A power plant in Iceland is set to become the first in the world to try turning carbon dioxide emissions into solid minerals underground, starting this September.

In an $11 million pilot project, Reykjavik Energy will capture CO2 from its plant, dissolve the gas in water and inject it deep into volcanic basalt nearby. Over the nine-month study, some 2,000 tons of greenhouse gas will be treated.
