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. It’s quite clear that these processes are not efficient. —Antoine Allanore.

Lightyear shelves solar EV plans, hires executives to spearhead solar systems for other OEMs

Baua Electric

Star-crossed startup Lightyear has finally thrown in the towel on attempting to bring its long-promised solar EVs to market – at least one donning its own badge and design language. Like many startups, the solar EV company demonstrated some inspiring and potential industry-changing technology, only to fall short due to a lack of funds.

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 could yield an estimated storage cost of about 6 cents per kilowatt-hour—a level considered viable by the utility industry. Earlier post.).

MITEI study finds hydrogen-generated electricity is a cost-competitive candidate for backing up wind and solar

Green Car Congress

A team at MITEI (MIT Energy Initiative) has found that hydrogen-generated electricity can be a cost-competitive option for backing up wind and solar. California draws more than 20% of its electricity from solar and approximately 7% from wind, with more VRE coming online rapidly. —Drake Hernandez.

MIT researchers develop oxygen permeable membrane that converts CO2 to CO

Green Car Congress

MIT researchers have developed a new system that could potentially be used for converting power plant emissions of carbon dioxide into carbon monoxide, and thence into useful fuels for cars, trucks, and planes, as well as into chemical feedstocks for a wide variety of products. Syngas is a widely used industrial fuel and feedstock.
