We would love to find ways to reduce carbon dioxide as a threat to our climate with an ever-decreasing timeline for accomplishing that task.  University of Illinois at Chicago and Massachusetts Institute of Technology (MIT) have made inroads into creating a carbon dioxide battery that uses CO2 as an energy storage component. Amin Salehi-Khojin, associate professor of mechanical and industrial engineering at UIC’s College of Engineering, explains, “Lithium-carbon dioxide batteries have been attractive for a long time, but in practice, we have been unable to get one that is truly efficient until now.” A 7X Battery The incentive to use CO2 comes from lithium-carbon dioxide batteries having a specific energy density more than seven times greater than conventional lithium-ion cells.  …

Photosynthesis Directly Makes Fuel

That’s what photosynthesis does in leaves – creates fuel in the form of plant sugars that flow into the plant to which the leaf is attached.  One of the main quibbles about trying to convert solar energy to usable fuel is the usual multi-step process involved.  Researchers at the University of Illinois at Chicago have made a major advance in creating a solar cell that captures carbon dioxide (CO2) and uses sunlight to make a synthetic gas that can be burned as fuel. Scientists rarely use hyperbolic terms such as “extraordinary” in their findings.  According to Amin Salehi-Khojin, assistant professor of mechanical and industrial engineering at UIC, “What we needed was a new family of chemicals with extraordinary properties.”  They …
