New concept with anthraquinone-based organic cathode advances aluminum battery technology

Green Car Congress

Researchers from Chalmers University of Technology, Sweden, and the National Institute of Chemistry, Slovenia, have developed a new concept for an aluminum battery delivering twice the energy density as previous versions, made of abundant materials, and with the potential to reduce production costs and environmental impact.

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.

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.

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.
