Turning carbon dioxide into liquid fuel (ethanol)
Quote:
This process would do so by electrochemically converting the CO2 emitted from industrial processes, such as fossil fuel power plants or alcohol fermentation plants, into valuable commodities at reasonable cost.

The team’s catalyst consists of atomically dispersed copper on a carbon-powder support. By an electrochemical reaction, this catalyst breaks down CO2 and water molecules and selectively reassembles the broken molecules into ethanol under an external electric field. The electrocatalytic selectivity, or ​“Faradaic efficiency,” of the process is over 90 percent, much higher than any other reported process. What is more, the catalyst operates stably over extended operation at low voltage.
Presumably it could work in conjunction with an atmospheric scrubber.

liquid fuel would be nice. but speaking of ethanol i see many more possibilities of application!

Such as?

I'd just like to see some of the related technology put to use at a large scale. Since economics don't seem to matter to some locales, conversion or operation shouldn't need to be commercially viable.

well if it would be pure and not methanol containing then you could drink it (after adding water). imagine vodka made out of air :)
or you could use it for reverse distillation of specific herbs infusions (there you need high alcohol percentage such as 99%) to make concentrates.
last but not least alcohol can be used for disinfection and cleaning.
