Seltzer Sequestration

Carbon capture and storage - taking CO2 emissions from burning fossil fuels at power plants and burying them underground in geological traps - has been proposed a a possible solution to our greenhouse gas problems.

But proponents haven't had an understanding of what might happen to carbon dioxide trapped underground over long periods of time.

Now Dr. Barbara Sherwood Lollar, a geologist at the University of Toronto, offers evidence. She, and her colleagues, found natural CO2 traps, and discovered that the gas mostly dissolves in underground water.
