MIT team exploring using LOHCs directly on-board hydrogen-fueled trucks

Green Car Congress

A team of MIT researchers led by William H. Green, the Hoyt Hottel Professor in Chemical Engineering, is developing a technology that allows liquid organic hydrogen carriers (LOHCs) not only to deliver hydrogen to the trucks, but also to store the hydrogen onboard. Proposed process flow diagram for onboard dehydrogenation.

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 researchers significantly increase lifetimes of solid oxide fuel cells by changing pH

Green Car Congress

MIT researchers have found that changing the pH of the system can increase the lifetimes of a range of technologies including fuel cells. Fuel and electrolysis cells made of solid metal oxides are of interest for several reasons. An open-access paper on their work is published in the RSC journal Energy & Environmental Science.

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 proposes SCR emission control for hybrid aviation turbines; reducing NOx by 95%

Green Car Congress

Now, MIT engineers are proposing using an ammonia-based selective catalytic reduction (SCR) system that could result in an approximately 95% reduction in NO x emissions in exchange for a ~0.5% increase in block fuel burn. Furthermore, SCR systems require ultra-low sulfur (ULS) fuel to prevent catalytic fouling.

MIT Looks Ahead to Hydrogen’s Aviation Future

Cars That Think

John Hansman , an aeronautics and astronautics professor at MIT and director of the university’s International Center for Air Transportation. The pipeline-and-hydrant option is the best option from an engineering perspective. Hydrogen, Hansman adds, is extremely flammable, which means fuel lines would need to be cleared.

MIT proof-of-concept demo of ionic wind propulsion for aircraft

Green Car Congress

MIT researchers have demonstrated that an aircraft with a 5-meter wingspan can sustain steady-level flight using ionic-wind propulsion. The aircraft has no moving parts, does not depend on fossil fuels to fly, and is completely silent. Most have been powered by fossil-fuel combustion. —Xu et al.
