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. The findings could spur progress on developing a variety of materials and designs for electrochemical carbon dioxide conversion systems. —Soto et al.

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. —MITEI Director Ernest J.

MIT researchers advancing development of supercritical water upgrading of heavy crude; lower cost, energy use and CO2

Green Car Congress

Findings by MIT researchers could help advance the commercialization of supercritical water technology for the desulfurization and upgrading of high-sulfur crude oil into high-value, cleaner fuels such as gasoline without using hydrogen—a major change in refining technology that would reduce costs, energy use, and CO 2 emissions.

DOE awards $7M to eight oxy-combustion coal technology projects; carbon capture, utilization and storage

Green Car Congress

The oxy-combustion process replaces the air used for combustion with a mixture of oxygen and recycled plant emissions (flue gas) and/or water for temperature control. The CDCL process consists of a unique moving bed reactor where pulverized coal is fully converted using iron-based oxygen carriers. Gas Technology Institute.
