MIT team proposes flex-fuel gasoline-alcohol engine PHEV long-haul trucks

Green Car Congress

In a paper being presented at WCX SAE World Congress Experience in Detroit this week, a team from MIT is proposing the use of a flex-fuel gasoline-alcohol engine approach for a series-hybrid powertrain for long-haul Class 8 trucks. Ethanol or methanol would be employed to increase knock resistance. —Daniel Cohn.

MIT team engineers yeast to be more tolerant to toxic byproducts, boosting biofuels production; “tolerance module”

Green Car Congress

In the US, ethanol production is limited in large part by its reliance on corn, which isn’t grown in large enough quantities to make up a significant portion of US fuel needs. To try to expand biofuels’ potential impact, a team of MIT engineers has now found a way to expand the use of a wider range of nonfood feedstocks to produce such fuels.

MIT team testing new SiC nuclear fuel-rod cladding that could lead to safer power plants

Green Car Congress

A team of researchers at MIT is developing and testing a new silicon carbide (SiC) cladding material for nuclear fuel rods that could reduce the risk of hydrogen production by roughly a thousandfold compared to the common zircaloy cladding. The results showed good strength retention during mechanical testing, Stempien says.

Researchers from MIT and Sun Catalytix develop an artificial leaf for solar water splitting to produce hydrogen and oxygen

Green Car Congress

Researchers led by MIT professor Daniel Nocera have produced an “artificial leaf”—a solar water-splitting cell producing hydrogen and oxygen that operates in near-neutral pH conditions, both with and without connecting wires. aligned with the low-cost systems engineering and. solar-to-fuels systems.

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.

MIT team discovers new family of materials with best performance yet for oxygen evolution reaction; implications for fuel cells and Li-air batteries

Green Car Congress

MIT researchers have found a new family of highly active catalyst materials that provides the best performance yet in the oxygen evolution reaction (OER) in electrochemical water-splitting—a key requirement for energy storage and delivery systems such as advanced fuel cells and lithium-air batteries.

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. Ghoniem’s lab is exploring some of these options.
