Utah leading CO2 Sequestration - The U.S. Department of Energy (DOE) plans to spend $67 million over the next decade on a technology solution for climate change that will be tested in Utah. Plans call for pumping carbon dioxide into mile-deep rock formations for long-term underground storage. (Salt Lake Tribune; Nov. 16, 2007)

CO2 captured in solution while making electricity - M.T. Keshe claims to have come up with an inexpensive method for generating electricity through the capture of CO2 and methane gases in the air while converting them into solution and solid. Imagine generating energy from gobbling up CO2 an CH4, inexpensively; producing O2 as a byproduct. Could this be real? (PESWiki; Dec. 23, 2009) (Comments)

Cement from CO2: A Concrete Cure for Global Warming? - While Calera's process of making calcium carbonate cement wouldn't eliminate all CO2 emissions, it would reverse that equation. "For every ton of cement we make, we are sequestering half a ton of CO2," says crystallographer Brent Constantz, founder of Calera. "We probably have the best carbon capture and storage technique there is by a long shot." (Scientific American; August 7, 2008)

Creating A Carbon Economy - Sequestered Carbon Amendment and Fertilization (SCAF) has developed new systems to make carbon sequestration profitable and create a new carbon economy instead of treating it as waste. They use elemental carbon as a soil amendment for soil recovery and improvement, better water and mineral management in addition to using carbon dioxide as plant food or fertilizer.
