MIT researchers propose mechanism for overcoming bottleneck in electroreduction of CO2

Green Car Congress

Researchers at MIT have identified , quantified, and modeled a major reason for the poor performance of electroreduction processes to convert CO 2 to fuel or other useful chemicals. There’s a number of groups working on this, and a number of catalysts that are out there. —Soto et al. —Kripa Varanasi.

MIT researchers develop oxygen permeable membrane that converts CO2 to CO

Green Car Congress

MIT researchers have developed a new system that could potentially be used for converting power plant emissions of carbon dioxide into carbon monoxide, and thence into useful fuels for cars, trucks, and planes, as well as into chemical feedstocks for a wide variety of products. Syngas is a widely used industrial fuel and feedstock.

MIT Report Finds Natural Gas Has Significant Potential to Displace Coal, Reducing Greenhouse Gas Emissions; Role in Transportation More Limited

Green Car Congress

Natural gas will play a leading role in reducing greenhouse-gas emissions over the next several decades, largely by replacing older, inefficient coal plants with highly efficient combined-cycle gas generation, according to a major new interim report out from MIT.

The same is true in reverse, when solar panels lose some of the energy in photons as heat instead of it all being converted into electrons. A thermophotovoltaic (TPV) cell developed by engineers at MIT has eclipsed the 40-percent-efficiency mark. But the tide looks to be turning. Felice Frankel One Large Rat, Hold the Droppings.

False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

They wanted to see whether an electric vehicle could feed electricity back to the grid. The concept behind V2G had gained traction in the late 1990s after California’s landmark zero-emission-vehicle (ZEV) mandate went into effect and compelled automakers to commercialize electric cars. AC Propulsion’s experiment was timely.
