Capturing Carbon Dioxide From Air Would Be Inefficient, Princeton Study Says

Ovidiu Sandru — Mon, 09 May 2011 18:40:50 +0000

The carbon dioxide that we emit can be reduced in several ways, out of which some are more or less effective. A study performed by Princeton engineer Robert Socolow reveals that as much as we'd want to, we simply can't remove carbon dioxide and other greenhouse gases by means of "Direct Air Capture" technologies.

Technology For Making Construction Materials Out Of Carbon Dioxide Inspired By Sea Snail

Ovidiu Sandru — Thu, 23 Sep 2010 05:01:59 +0000

The thing on the left is a snail, and it's called abalone. Aside the fact that it's edible, the abalone taught Angela Belcher, from MIT, how to turn carbon dioxide into rock-solid construction materials and thus sequester the gas for hundreds of thousands of years, instead of burying it underground, which is not as safe and as useful.

Dry Water Shown to Be Effective in Trapping CO2 Emissions

Ovidiu Sandru — Thu, 26 Aug 2010 17:16:18 +0000

A sugar-resembling substance that can absorb carbon dioxide within itself has been developed by a team led by Andrew Cooper, from the University of Liverpool, in the UK. The substance is called "dry water", because it's made of water and because it's dry, containing silica.

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.

Study: Salt Water Can Keep the Injected CO2 Underground

Ovidiu Sandru — Sat, 22 Nov 2008 20:45:19 +0000

We are now trying to bury the CO2, get rid of it somehow, and if fossil fuels came from down below, we think that by sending CO2 from where it came, we will solve the problem partially. And that may be true, regarding that sometimes the patchy solutions are best. So, let's try to patch our trouble.
