Waste Heat Used to Capture Emitted Carbon Dioxide

Mila Luleva — Fri, 29 Mar 2013 19:58:23 +0000

An economical way to capture CO2 from the atmosphere using waste heat, was established by researchers at Rice University. This method is a break-through in CO2 capturing, because most conventional techniques are energy intensive and use up high-pressure steam, valuable for electricity production. The research published in the latest issue of the International Journal of […]

Carbon Stored in Soil to Rise Again, Study Says

Janina Lazo-Cruz — Wed, 07 Nov 2012 17:17:29 +0000

After discovering that soil erosion can actually store some carbon dioxide from the atmosphere, acting as a carbon sink, a recent discovery reveals that after some time it can also be a carbon source as its stored carbon will rise up again back to the atmosphere. Researchers at the University of California – Davis have […]

A Novel Material for CO2 and SO2 Capture

Janina Lazo-Cruz — Fri, 26 Oct 2012 13:52:47 +0000

A new hope arises for carbon capture and storage as a new material synthesized by researchers of United Kingdom’s University of Nottingham was discovered to be safe and nontoxic to environment and economical that can selectively adsorb CO2 and SO2 gases and regenerate easily, as reported in its article recently published in Nature Chemistry. Most of […]

New Cerium Oxide CO2-Adsorbing Material Created by Hitachi 13 Times More Efficient

Ovidiu Sandru — Tue, 03 Apr 2012 18:33:30 +0000

A new CO2-adsorbing material based on cerium oxide has been created by Hitachi. It has been designed to capture the CO2 produced by coal-fired plants and the company says it’s 13 times more efficient than old zeolitic solid adsorbents. Because old materials adsorb moisture existing in the gas, they’re not very good at separating CO2 […]

MIT Finds How Carbon Dioxide Could Be Sunk Into the Ground Forever

Ovidiu Sandru — Wed, 21 Mar 2012 13:50:27 +0000

Deep saline aquifers in the U.S. could be the solution for storing the CO2 outputted from coal power plants in the long run, thus making them cleaner and the energy cheaper. It’s not that I turned into preaching people how to get along with coal (again), but the solution really sounds simple and, if it’s […]

French Researcher Develops Impressive Pollution-Eating Streetlights Using Microalgae

Ovidiu Sandru — Fri, 09 Mar 2012 19:04:06 +0000

Fermentalg, the company founded and led by French researcher Pierre Caleja, has recently developed street lighting that could one day soak CO2 from the air with the use of microalgae. Caleja’s company had received several millions in funding from various private investors in recent years to discover ways of harvesting the power of microalgae to […]

Genetically Modified Enzyme Leads to Better Carbon Sequestration at Coal Powered Plants

Ovidiu Sandru — Sat, 24 Jul 2010 20:02:14 +0000

Capturing the carbon dioxide that a coal-powered plant produces and sequestering it is not an easy task, and until now it rose the costs of the electricity produced by 80 percent. Due to researchers at Codexis, a Redwood, CA, company, genetically modified enzymes can make carbon dioxide capture much cheaper, increasing the cost of electricity by less than a third.

Space Rocket Nozzle Technology Could Capture CO2 and Turn It Into Dry Ice

Ovidiu Sandru — Fri, 09 Jul 2010 07:52:36 +0000

ATK, a company that builds the space shuttles' booster rockets may have a solution for the massively-polluting coal power plants, by using rocket nozzle technology to turn the carbon dioxide into dry ice, and capture it easier than they can do with chemicals.

Hair Conditioning Shampoo Component Captures 90% of Coal Plants' CO2

Ovidiu Sandru — Fri, 26 Mar 2010 14:48:44 +0000

Aminosilicones are regularly used in hair-conditioning shampoos and fabric softeners, but recently they show usefulness in fighting global warming by filtering carbon dioxide out of flue gases from coal plants.

DNA-Like Metal Organic Frameworks to Store Carbon Dioxide Efficiently

Ovidiu Sandru — Fri, 12 Feb 2010 19:21:02 +0000

UCLA scientists, led by professor Omar M. Yaghi have created three-dimensional, synthetic DNA-like crystals which are capable of storing carbon dioxide: We have taken organic and inorganic units and combined them into a synthetic crystal which codes information in a DNA-like manner.

A Cleaner And More Efficient Way to Capture Carbon Dioxide

Florin — Sun, 26 Jul 2009 15:25:04 +0000

The process of separating CO2 from its source is called capturing (CO2). The new method discovered by the scientists from Lawrence Livermore National Laboratory might replace all the existing Carbon Dioxide capturing devices and improve a lot their performance and stability.

Capturing CO2 is one of the many tasks trees have been doing for ages. Now, though, with all the CO2 being emitted into the atmosphere and the trees being cut off, the existing forests are not able to keep up with the ongoing pollution.
