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. The key to this Ocean Renewable Energy Storage (ORES) system is the placement of 30-meter-diameter hollow concrete spheres on the seafloor under the wind turbines. 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. Much of this information was publicly available.

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.

New MIT metal-mesh membrane could solve longstanding problems with liquid metal displacement batteries; inexpensive grid power storage

Green Car Congress

A new metal mesh membrane developed by researchers at MIT could advance the use of the Na–NiCl 2 displacement battery, which has eluded widespread adoption owing to the fragility of the ?"-Al through the MIT Energy Initiative. Al 2 O 3 membrane. A paper describing the development is published in the journal Nature Energy.

MIT study finds shift to green energy sources could mean crunch in supply of key rare earth elements

Green Car Congress

The study by researchers at MIT also points out that production of the two metals has been increasing by only a few percentage points per year.the availability of REEs appears to be at risk based on a number of factors. While the literature contains a number of reports that evaluate different aspects of RE availability, Randolph E.

MIT team improves liquid metal batteries for grid-scale storage; lower operating temperature, cost

Green Car Congress

Researchers at MIT have improved a proposed liquid battery system that could enable renewable energy sources to compete with conventional power plants. Such systems can be used to match the intermittent production of power from irregular sources, such as wind and solar power, with variations in demand. Earlier post.).

Total Signs Research Agreement with MIT to Develop New Stationary Batteries for Solar Power; Smaller-Scale Version of All-Liquid Metal Battery Work Supported by ARPA-E

Green Car Congress

Total has signed a research agreement with the Massachusetts Institute of Technology (MIT) to develop new stationary batteries that are designed to enable the storage of solar power. This agreement valued at $4 million over five years is part of the MIT Energy Initiative (MITEI), which Total joined as a member in November 2008.
