MIT researchers propose subsea version of pumped hydro for renewable energy storage

Green Car Congress

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. These structures would serve both as anchors to moor the floating turbines and as a means of storing the energy they produce. Earlier post.).

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.

RMIT researchers develop concept “proton flow battery”

Green Car Congress

RMIT University (Australia) researchers have developed a concept battery based on storing protons produced by splitting water—a reversible fuel cell with integrated solid proton storage electrode. The concept integrates a composite metal hydride–nafion electrode into a reversible proton exchange membrane (PEM) fuel cell.
