• Researchers at Massachusetts Institute of Technology (MIT) have developed a new system that could potentially be used for converting power plant emissions of carbon dioxide (CO2) into useful fuel for cars, trucks and planes.
• The new method, described in a paper in the journal ChemSusChem , is based on a membrane-based system.
• The membrane, made of a compound of lanthanum, calcium, and iron oxide, allows oxygen from a stream of carbon dioxide to migrate through to the other side, leaving carbon monoxide behind.
• Carbon monoxide produced during this process can be used as a fuel by itself or combined with hydrogen and/or water to make many other liquid hydrocarbon fuels as well as chemicals including methanol (used as an automotive fuel).
