IIASA-led study proposes Underground Gravity Energy Storage as long-term energy storage solution for renewables

Green Car Congress

Renewable energy sources are central to the energy transition toward a more sustainable future. However, because sunshine and wind are inherently variable and inconsistent, finding ways to store energy in an accessible and efficient way is crucial.

What is energy storage?

Setec Powerr

Growing demand for renewable energy, an aging electrical grid, costly grid infrastructure improvements, and increasing extreme weather events will require increased energy flexibility to help the grid balance intermittent supply with responsive demand. In addition, these systems offer a wide range of benefits to energy users.

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.

NSF awards UCSD team $39M to improve integration of distributed energy resources into grid; EV batteries also

Green Car Congress

A major current obstacle to the adoption of such technologies in the operations of real energy systems is the development of realistic test cases on a realistic scale. Most utilities struggle with the fact that renewable and distributed energy sources are not as stable as traditional sources, such as natural-gas power plants.
