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.).

MIT Researchers Find That Elastic Energy Storage Systems Built With Carbon Nanotubes Could Match Li-ion Battery Energy Densities

Green Car Congress

Energy density of single-walled CNT (SWCNT) bundles under tensile loading with support structures made of single crystal diamond, silicon and silicon carbide. the molecular scale, CNTs can function as mechanical springs that store a great deal of energy for their size due to their networks of strong carbon–carbon bonds.

National University of Singapore researchers devise membrane-based supercapacitors; possible new route to high-performance supercapacitive energy storage

Green Car Congress

Unlike more conventional supercapacitor electrode materials with large surface areas and high porosities, the new hydrophilized polymer network uses ion-conducting channels for fast ion transport and charge storage. When sandwiched between and charged by two metal plates, the membrane can store charge at 0.2

MIT team studies grid impacts of concentrated highway EV fast charging

Green Car Congress

Researchers at the MIT Energy Initiative have investigated the grid impacts of scaled up highway fast-charging (HFC) infrastructure by using an operations model of the 2033 Texas power grid with uniquely high spatial and temporal resolution. Transmission network upgrades can also effectively mitigate grid-HFC interactions.
