MIT, Scripps study examines behavior of midwater sediment plumes from deep-sea nodule mining

Green Car Congress

Now, oceanographers at MIT, the Scripps Institution of Oceanography, and elsewhere have carried out an experiment at sea for the first time to study the turbulent sediment plume that mining vessels would potentially release back into the ocean. —Thomas Peacock, professor of mechanical engineering at MIT and co-corresponding author.

MIT electrolyte enables ultra-high voltage Ni-rich cathodes in Li-metal batteries

Green Car Congress

MIT researchers and colleagues at two national laboratories have developed a sulfonamide-based electrolyte that enables stable cycling of a commercial LiNi 0.8 In a paper in the journal Nature Energy , the MIT team reports that a lithium-metal battery with the electrolyte delivers a specific capacity of >230?mAh?g

Megawatt Electrical Motor Designed By MIT Engineers Could Help Electrify Aviation

CleanTechnica EVs

To electrify larger, heavier jets, such as commercial airliners, megawatt-scale motors are required. To date, however, only small all-electric planes have gotten off the ground. Their electric motors generate hundreds of kilowatts of power. These would be propelled by hybrid or turbo-electric propulsion systems where an […]

MIT team reexamines rates of Li-ion cost decline

Green Car Congress

Now, MIT researchers have carried out an exhaustive analysis of the studies that have looked at the decline in the prices these batteries. For both, we find that the real price of lithium-ion cells, scaled by their energy capacity, has declined by about 97% since their commercial introduction in 1991. —Ziegler and Trancik.

MIT Looks Ahead to Hydrogen’s Aviation Future

Cars That Think

As investment in hydrogen-powered flight expands , airports and air carriers today are realizing that it’s not enough to retrofit or design new planes for hydrogen power. John Hansman , an aeronautics and astronautics professor at MIT and director of the university’s International Center for Air Transportation. asks Professor R.

MIT: hybrid cathodes could boost energy capacity of lithium-sulfur batteries

Green Car Congress

Researchers at MIT and in China are proposing a new class of dense intercalation-conversion hybrid cathodes by combining intercalation-type Mo 6 S 8 with conversion-type sulfur (HMSC) to realize a Li–S full cell. Design strategy for jointly high gravimetric–volumetric energy density. 1 and a volumetric energy density of 581?Wh?l

MIT-Led Team Designs Two Airplanes That Would Use 70% Less Fuel Than Current Models

Green Car Congress

An MIT-led team has designed an airplane that is estimated to use 70% less fuel than current planes while also reducing noise and emission of NO x. The design was one of two that the team, led by faculty from the Department of Aeronautics and Astronautics, presented to NASA last month as part of a $2.1 Click to enlarge.
