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. Preliminary estimates indicate that one such sphere could be built and deployed at a cost of about $12 million, Hodder says, with costs gradually coming down with experience.

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

Green Car Congress

A team of MIT researchers led by William H. Regardless of technical improvements, these existing options remain prohibitively expensive due to the high cost of retail hydrogen delivery. Their findings were recently published in the ACS journal Energy and Fuels.

MIT, Brookhaven team develops simple method for stabilizing interfaces in solid-state lithium-ion batteries

Green Car Congress

Now, a team of researchers at MIT and Brookhaven National Laboratory has developed a way of achieving results that equal or surpass the durability of the coated surfaces, but with no need for any coatings. The findings are reported in an open-access paper in the journal Advanced Energy Materials.

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 study attributes > 50% of Li-ion rapid cost decline to investment in materials & chemistry R&D

Green Car Congress

The cost of Li-ion batteries has plunged some 97% since their introduction three decades ago—a rate similar to the drop in solar panel prices. The researchers looked at academic articles, industry and government reports, press releases, specification sheets and legal filings, says MIT postdoc Micah Ziegler.

MIT, GE, Audi launch HubCab Project in New York City

Green Car Congress

MIT, in partnership with Audi and GE, has launched HubCab —a transportation tracking tool aimed at reducing commuting congestion, decreasing vehicle emissions and lowering the cost of mobility infrastructure. HubCab tracks more than 150 million taxi rides in New York City over the course of a year.
