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. However, their commercial viability has been hampered, in part, because they degrade over time. Fuel and electrolysis cells made of solid metal oxides are of interest for several reasons.

MIT study: half of US deaths related to air pollution are linked to out-of-state emissions

Green Car Congress

More than half of all air-quality-related early deaths in the United States are a result of emissions originating outside of the state in which those deaths occur, MIT researchers report in a paper in the journal Nature. To make further progress, we should start focusing on road transportation and commercial and residential emissions.

MIT Professor’s IoT Sensors Make Roads Safer

Cars That Think

Back in 2005, before smartphones were generally available, MIT Professor Hari Balakrishnan was so fed up with commuting delays in Boston that he built a mobile system to monitor road conditions. In 2010 Balakrishnan and two cofounders commercialized CarTel by launching Cambridge Mobile Telematics. Help came in 2009 from William V.

NREL, MIT, WSU team develops process to convert lignin to aromatic blendstock for 100% sustainable aviation fuel

Green Car Congress

Current commercialized technologies do not produce those components to qualify for a 100% SAF. Previous research has yielded lignin oils with high oxygen contents ranging from 27% to 34%, but to be used as a jet fuel that amount must be reduced to less than a half-percent. A paper on their work is published in Joule. Heyne, Gregg T.

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. This is comparable to some commercial batteries, indicating that the new device does match its predicted characteristics.

MIT researchers developing LiDAR on a chip

Green Car Congress

Today, commercially available high-end LiDAR systems can range from $1,000 to upwards of $70,000, which can limit their applications where cost must be minimized. Applications such as autonomous vehicles and robotics heavily depend on LiDAR, and an expensive LiDAR module is a major obstacle to their use in commercial products.

Nissan says it will have first commercially-viable autonomous drive vehicles by 2020; across the range in 2 vehicle generations

Green Car Congress

announced that the company will be ready with multiple, commercially-viable autonomous drive (AD) vehicles by 2020. Nissan said that its engineers have been carrying out intensive research on the technology for years, alongside teams from universities including MIT, Stanford, Oxford, Carnegie Mellon and the University of Tokyo.
