This Sounds Promising

Whether this will turn out to be another idea that holds great promise but then comes to nothing will only be known, I guess, in the future, but it does sound promising:

The danger of the ever-increasing levels of carbon dioxide (CO2) in Earth's atmosphere has become one of the most pressing issues of our age. As such, much research has been conducted to find ways not only to reduce it, but also in ways to remove it. This has led to many schemes that simply sequester CO2 underground, or store it in volcanic rocks. More ambitious schemes even aim to not only remove this gas, but to usefully employ it to create usable products, such as plastics and foam, or even to produce hydrocarbon fuels. Now scientists from the Oak Ridge National Laboratory (ORNL) claim to have produced one of the most usable of all chemicals – ethanol – in a process that is not only cheap, efficient, and scalable, but also conducted at room temperature.
