CO2 in the atmosphere is very important for life on earth and therefore CO2 is one of my favorite chemical compounds. The oil and gas industry injects CO2 from the atmosphere down into oil wells thus reducing the alleged greenhouse gas in the atmosphere.
Ocean floors are made of basalt, the hardened lava that erupts from undersea fissures or volcanoes. David Goldberg, a Columbia geophysicist, writing in the Tuesday edition of The Proceedings of the National Academy of Sciences of America, said basalt and CO2 interact in a chemical process that converts the carbon into a carbonate, or chalk-like substance.
What makes the deep sea storage option more appealing is the added protective layer of the water itself, which at depths of greater than 2,700 m is not as dense as liquid carbon dioxide or the CO2 hydrates that can form, creating an added layer of protection to keep the CO2 down.
Goldberg and his colleagues said the basement of the Juan de Fuca plate alone could hold approximately 250 gigatonnes (Gt) of carbon, or sufficient storage for 122 to 147 years worth of U.S. emissions, based on the current annual emission rate of 1.7 Gt of carbon per year.
"The injection of CO2 in deep-sea basalt offers critical advantages for sequestration that warrant pressing investigation," wrote Goldberg, who called for a pilot injection study.

I think I'll go burn some more hydrocarbons now. I love the smell of crude oil in the morning.
