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.).

Scientists have increased the life of fuel cells – why that matters for solar and wind

Electrek

In research that could jumpstart work on a range of technologies including fuel cells – key to storing solar and wind energy – MIT researchers have found a relatively simple way to increase the lifetimes of these devices: changing the “pH” of the system.

Liquid Metal Battery Corp secures patent rights from MIT

Green Car Congress

Liquid Metal Battery Corporation (LMBC), a Cambridge, Massachusetts company founded in 2010 to develop new forms of electric storage batteries that work in large, grid-scale applications, has secured the rights to key patent technology from MIT. Patents for all liquid metal battery inventions were licensed from MIT.

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.

DOE announces $11.5M in Phase 1 funding for carbon capture and storage program; ARPA-E FLECCS

Green Car Congress

UNO MK3 allows CO 2 to be withdrawn and stored as solid potassium bicarbonate during high energy demand, eliminating stripper energy and enabling profitable regeneration. Next, the CO2-rich gas (>30% CO 2 ) from the calciner is separated to recover high-purity CO 2 , which can be stored. Colorado State University.

The Vacuum Tube’s Forgotten Rival

A second wire also wrapped around the core forms a control winding. The control winding includes many turns of wire, so by passing a relatively small direct current through it, the iron core can be forced into or out of saturation. After winding, the module was annealed in hydrogen at 1,100 °C for 2 hours and then rapidly cooled.

Liquid metal battery company Ambri raises $35M in Series C

Green Car Congress

The energy is stored in the liquid metals that want to react with one another but can do so only by transferring ions across the electrolyte, which results in the flow of electric current out of the battery. Sadoway’s basic principle is to place three layers of liquid inside a container: two different metal alloys (e.g.,
