A new analysis led by an MIT scientist describes a mechanism for capturing carbon dioxide emissions from a power plant and injecting the gas into the
ground, where it would be trapped naturally as tiny bubbles and safely stored in briny porous rock.
Full Story
This means that it may be possible for a power plant to be built in an appropriate location and have all its carbon dioxide emissions captured and
injected underground throughout the life of the power plant, and then safely stored over centuries and even millennia. The carbon dioxide eventually
will dissolve in the brine and a fraction will adhere to the rock in the form of minerals such as iron and magnesium carbonates.

"We also found that by injecting water along with the CO2, we can optimize sequestration,"
As long as the Undergorund location is not connected to a water source/undergorund water tunnel this sounds like a really good alternative
