Here is an article from 30 April 2007 issue of Chemical & Engineering News about chemical processes to use CO2.

So what's one to do with CO2?
C&EN asked that question of a number of chemists and chemical engineers. These investigators were unanimous on the scope of the CO2 problem. They understand that technology to capture large amounts of CO2 and sequester it deep underground or under the seafloor probably is going to be necessary if humanity decides it wants to reduce the gas's expected effects on the planet's climate. But they also are optimistic that much good could come from a more focused research effort to find new ways to utilize CO2 as a chemical feedstock.

The Amine process is getting much more attention commercially as a CO2 capture process than using water. There are actually some commercial pilot scale facilities in use (
