This is a new option

Quote of the day

People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

New low cost material could help bolster carbon capture

RATE THIS! +3

Researchers at the University of Nottingham have developed another weapon in the ongoing war to reduce the amount of greenhouse gases emitted from fossil fuel-burning power plants. The researchers have created a new porous material called NOTT-300 that they claim is cheaper and more efficient than existing materials at capturing polluting gases, such as carbon dioxide and sulfur dioxide, from flue gas.

 

While a wholesale switch from the burning of fossil fuels to greener alternatives such as solar, wind and wave power technologies would be the most environmentally friendly way to meet our ever-increasing demand for electricity, the simple fact is that the move will only be made incrementally. Carbon capture and sequestration is seen by many as one of the necessary steps on the road to a greener future, but current methods are expensive and consume large amounts of energy themselves.

 

The University of Nottingham researchers claim their NOTT-300 material offers a marked improvement over existing carbon capture methods that use a solvent that adsorbs CO2 and then releases water vapor to leave a concentrated stream of CO2 when heated. In comparison, NOTT-300 boasts a high uptake of CO2 and SO2 and releases the adsorbed gas chemicals through a simple reduction of pressure.

 

The material is also highly selective, with little or no adsorption into its pores of other gases, such as hydrogen, methane, nitrogen or oxygen. It also boasts high chemical stability to all common organic solvents and is stable in water at temperatures of up to 400° C (752° F). Additionally, as it is synthesized from cheap organic materials with water as the only solvent, it is cheap to produce.
