A123 Systems to supply 1MW Li-ion grid storage system to Maui Electric Company; 2MW system for NSTAR demonstration

Green Car Congress

Li-ion battery maker A123 Systems will supply a Grid Battery System (GBS) to Maui Electric Company (MECO), a utility serving residents and businesses on the islands of Maui, Lanai and Molokai in Hawaii. The system, NSTAR’s first battery energy storage project, is proposed for installation at a substation in Medway, Mass.

Stanford study quantifies energetic costs of grid-scale energy storage over time; current batteries the worst performers; the need to improve cycle life by 3-10x

Green Car Congress

Using a new metric—“Energy Stored on Invested, ESOI”—they concluded that batteries were the worst performers, while compressed air energy storage (CAES) performed the best, followed by pumped hydro storage (PHS). The five battery technologies fared much worse. —Barnhart and Benson. PHS followed at 210.
