MIT membrane produces fuel from CO2 emissions

• by Rich Haridy

The process has been effectively demonstrated on a small-scale and the researchers hope to ultimately adapt the system to conventional fossil fuel-based power plants.

Made of lanthanum, calcium, and iron oxide, the membrane is designed to separate out oxygen from carbon dioxide, leaving behind carbon monoxide that can then be turned into a variety of useful fuels.

The process requires a significant energy input to produce the up to 990° C (1,814° F) temperatures needed to separate the carbon dioxide input into oxygen and carbon monoxide. But the researchers suggest this heat energy could be provided by either, "solar energy or by waste heat, some of which could come from the power plant itself."
