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.

EPRI study finds US energy storage market could be as large as 16 GW of capacity if systems can meet $700–$750/kWh and all benefits can be monetized

Green Car Congress

Positioning energy storage technologies. Further, the study found that actual installed costs would need to be lower to accommodate life-cycle impacts and maintenance. The analysis compared the present value of benefits with the estimated costs for energy storage systems installed in various regions across the US.

EPRI Analysis estimates costs of fully developing US smart grid could reach $476B; benefits up to $2T

Green Car Congress

The analysis updates EPRI’s 2004 EPRI assessment, which estimated the cost of implementing a smart grid at $165 billion. Mark McGranaghan, EPRI vice president of Power Delivery and Utilization, says the increased costs of the current analysis reflect a more advanced and expansive vision for the smart grid.
