Researchers turn CO2 into ethanol - by accident
A chemical reaction that converts CO2 into ethanol has been discovered, which could be a new method for mitigating climate change. Researchers at the Oak Ridge National Laboratory in Tennessee stumbled upon the finding while trying to identify a series of chemical reactions that could turn CO2 into a useful fuel. The technique works at room temperature, which means it could be used as temporary energy storage during lulls in renewable energy generation and help balance grids supplied by intermittent renewable sources.

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.
