  • 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)

    Power from CO2 and Fly Ash - By eliminating CO2 emissions, producing fuel, and reclaiming valuable metals from fly ash and flue emissions, MP BioMass offers technological solutions for coal power plants and other CO2 emitters to not only keep them from being shut down but increasing their profit margin. (PESN and BeforeItsNews; January 11, 2012)
  • GreenShift's CO2 Bioreactor - Patented process uses algae to consume greenhouse gas emissions from fossil-fueled power plants, giving off pure oxygen and water vapor. Light from concentrated solar panels is conducted into the algae chambers via fiber optics. Once the algae grows to maturity, it is harvested for conversion into ethanol and biodiesel fuels. (PESWiki)
  • Cement from CO2; A Concrete Solution to Global Warming - Calera Corporation has developed a nature-mimicking process that converts CO2, such as from a coal power plant, into cement; thus removing CO2 from the atmosphere in the process of making a product that usually produces a lot of CO2 using other methods. (PESWiki; August 20, 2008)

Methods

  • 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.
  • Solar > Device uses solar energy to convert carbon dioxide into fuel - Chemists at the University of California, San Diego have developed a prototype device that can capture energy from the sun, convert it to electrical energy and "split" carbon dioxide into oxygen and carbon monoxide, an important industrial chemical that is normally produced from natural gas. (Science Daily; Apr. 18, 2007)
  • US Hopes to Reverse Oil Decline by Burying CO2 - The Department of Energy and some environmentalists hope that in coming decades oil companies will expand programs that boost the output of aging oilfields by injecting the gas most scientists call the main culprit in global warming.

  • Clean coal technology for capture of CO2 - Babcock & Wilcox and American Electric Power are exploring bringing to market a new combustion technology to reduce emissions from coal-fired power plants. Oxy-coal combustion uses pure oxygen by eliminating nitrogen from the air, assisting CO2 capture and sequestration. Inside Greentech; Mar. 15, 2007)

Research & Development

  • SYNTHETIC TREE CAPTURES CARBON 1,000 FASTER THAN REAL TREES - Scientists have designed a synthetic tree that traps carbon dioxide from the air in an attempt to combat growing emissions. The device looks less like a tree and more like a small building, but it can collect carbon about 1,000 times faster than a real tree. (PhysOrg.com July 09, 2009)

    New Way to Convert CO2 into Methanol - Scientists at the Singapore-based Institute of Bioengineering and Nanotechnology (IBN) have achieved an unparalleled feat by transforming carbon dioxide into methanol. Methanol (natural gas) is a widely used form of industrial feedstock and clean-burning biofuel. (Alternative Energy blog; April 28, 2009)
  • Nanotechnology >
    Sun-powered device converts CO2 into fuel - Powered only by natural sunlight, an array of nanotubes is able to convert a mixture of carbon dioxide and water vapour into natural gas at 20 times higher than with other nanotech methods. (New Scientist; Feb. 18, 2009)
  • Biofuels / CO2 Sequestration >
    Could your breath be turned into biofuel? - The Liverpool John Lennon Airport is testing out a device called an Ecobox from Origo Industries that will capture CO2 from the air that’s exhaled by passengers and turn it into fuel to be used by the airport’s diesel vehicles and heating system. (Greener.Ideal; Feb. 6, 2009)
  • Capturing Carbon - An eighth-grader's science fair project prompts her scientist father to develop a new way to pull excess carbon dioxide out of the atmosphere. Geophysicist Klaus Lackner from Columbia University answers questions on carbon capture and storage. (NOVA ScienceNOW; July 2, 2008)

    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)

Super Diamonds – "Permanent" CO2 Sequestration - Robert Pritchet reviews the industry that could start with CO2 as a building block and end up with Super Diamonds which have great electronic properties. (Mac Companion; May 2010)
  • Breakthrough Science: Turning CO2 into Fuels - Carbon Sciences recently announced a technological breakthrough that is capable of transforming CO2 emissions into fuel. The development utilizes a highly scalable bio-catalytic process to economically convert one of the most omnipresent causes of global warming, CO2, into the basic building blocks of most fuels used to drive transportation and industry today.
