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.

New lithium polysulfide flow battery for large-scale energy storage

Green Car Congress

Researchers from the US Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University have designed a new lithium/polysulfide (Li/PS) semi-liquid (flow) battery for large-scale energy storage, with lithium polysulfide (Li 2 S 8 ) in ether solvent as a catholyte and metallic lithium as an anode.

To Store or Not to Store: That is the Question

Green Car Congress

“ Why do you need energy storage on the grid, when the grid is full of power plants that generate all the energy that is needed? Due to the inherent capital costs and characteristics of the leading alternative energy mediums: Hydro, Wind and Solar, Solar deployment has started to emerge as the leading candidate of choice.

Wind-to-Hydrogen Tech Goes to Sea

Cars That Think

Wind and solar parks produce a large portion of their energy. Then, as now, wind farms are operating off the world’s coasts—but not all of these offshore sites are connected to the mainland via underwater power cables. Some of the wind farms instead sit in clusters more than 100 kilometers out at sea.

5 Big Ideas for High-Temperature Superconductors

Cars That Think

But the materials could show up sooner in a wide array of practical applications, including wind power, energy storage, and nuclear magnetic-resonance machines. Once the coil is charged, the energy can be stored nearly indefinitely with little to no decay, provided that the cooling is maintained.

End of production for BMW i3; 250,000 units over 8 and a half years

Green Car Congress

The holistic concept for sustainability also includes the extensive use of renewable energy in the production of the BMW i3. Four wind turbines on the site of the BMW Group plant in Leipzig supply the electricity needed for its production. The BMW Group plant in Leipzig also has such an energy storage farm.
