Scientists at the Oak Ridge National Laboratory in Tennessee have discovered a chemical reaction to turn CO2 into ethanol, potentially creating a new technology to help avert climate change. Their findings were published in the journal ChemistrySelect (external - login to view).

The researchers were attempting to find a series of chemical reactions that could turn CO2 into a useful fuel, when they realized the first step in their process managed to do it all by itself. The reaction turns CO2 into ethanol, which could in turn be used to power generators and vehicles.

The tech involves a new combination of copper and carbon arranged into nanospikes on a silicon surface. The nanotechnology allows the reactions to be very precise, with very few contaminant

"By using common materials, but arranging them with nanotechnology, we figured out how to limit the side reactions and end up with the one thing that we want," said Adam Rondinone.

This process has several advantages when compared to other methods of converting CO2 into fuel. The reaction uses common materials like copper and carbon, and it converts the CO2 into ethanol, which is already widely used as a fuel.

Perhaps most importantly, it works at room temperature, which means that it can be started and stopped easily and with little energy cost.

"A process like this would allow you to consume extra electricity when it's available to make and store as ethanol," said Rondinone.


"This could help to balance a grid supplied by intermittent renewable sources."

The researchers plan to further study this process and try and make it more efficient. If they're successful, we just might see large-scale carbon capture using this technique in the near future.

Well, to turn CO2 into ethanol, you'll need some hydrogen.

Excellent way to collect a carbon tax on the way in and the way out.

Water's better'n half full of it - even undrinkable stuff

True, but the article mentions copper and carbon.

Can it be scaled up or us this another

Kill a plant for a bottle of gentle rye? . . . . count me in for a gallon a week. More if company is coming.

Oh yeah, it has to still be a liquid at -60C, almost forgot that little detail?

You should try pulling youth head out of your a$$ and read the article. Better yet, don't come to the forum when you're high
