Turning carbon emissions into methane fuel

Chemists have developed a novel way to capture and convert carbon dioxide into methane, suggesting that future gas emissions could be converted into an alternative fuel using electricity from renewable sources. Carbon dioxide (CO2) is a greenhouse gas that accounts for a large part of Earth's warming climate, and is produced by power plants, factories and various forms of transportation.

Typical carbon capture systems aimed at reducing its presence in the atmosphere work to lower carbon dioxide emissions by isolating CO2 from other gases and converting it to useful products.
