MIT researchers develop optimized sulfidation separation process for rare earth and other key metals

Green Car Congress

New processing methods developed by MIT researchers could help ease looming shortages of the essential metals that power everything from phones to automotive batteries by making it easier to separate these rare metals from mining ores and recycled materials.

MIT researchers propose subsea version of pumped hydro for renewable energy storage

Green Car Congress

Researchers at MIT are proposing using a variation on pumped hydroelectric systems for storage of electricity produced by offshore wind farms. This energy source could be made available within minutes, and then taken offline just as quickly. When demand is high, the water is released through turbines that generate electricity.

MIT, Stanford and Toyota Research Institute use AI to predict accurately the useful life of batteries

Green Car Congress

Scientists at the Massachusetts Institute of Technology (MIT), Stanford University and the Toyota Research Institute (TRI) have discovered that combining comprehensive experimental data and artificial intelligence provide the key for accurately predicting the useful life of lithium-ion batteries before their capacities started to wane.

MIT study finds fuel economy standards are 6-14 times less cost effective than fuel tax for reducing gasoline use

Green Car Congress

In a study published in the journal Energy Economics , MIT researchers have found that a fuel economy standard is at least six to fourteen times less cost effective than a fuel tax when targeting an identical reduction in cumulative gasoline use (20% by 2050). —Karplus et al.

MIT study finds real-world NOx from diesels cars in Europe greatly exceeds laboratory levels; transboundary emissions cause 70% of health impacts

Green Car Congress

A new study by MIT researchers, published this month in Atmospheric Environment , finds that in Europe, 10 major auto manufacturers produced diesel cars, sold between 2000 and 2015, that generate up to 16 times more NO x emissions on the road than in regulatory tests—a level that exceeds European limits but does not violate any EU laws.

MIT and IEA reports take different views of the future of natural gas in transportation

Green Car Congress

MIT and the IEA both have newly released reports exploring the potential for and impact of a major expansion in global usage of natural gas, given the current re-evaluation of global supplies. MIT: leaning toward conversion for light-duty vehicles. Earlier post.) I.e., on an energy basis at the point of use, the CO 2.

MIT/RAND Study Concludes Three Types of Alternative Jet Fuel May Be Available in Commercial Quantities Over the Next Decade

Green Car Congress

The focus of the work was on alternative jet fuels that could be available commercially in the next decade using primarily North American resources. Production of commercial quantities of HRJ depends on the availability of appropriate feedstocks at competitive prices. From Hileman et al. Click to enlarge. Hileman, David S.
