NOW AND FUTURE ENERGY BATTERY STORAGE

Li-ion Dominates the Booming Grid Storage Market with 90% of 2014 Proposals; Molten salt batteries still account for a majority of existing grid storage installations, but Li-ion is rapidly taking over as the market matures…

“…Li-ion accounted for 419 MW and 1,555 MWh of proposed storage systems in 2014. But molten salt batteries – consisting almost entirely of sodium-sulfur (NaS) – account for 23% of all deployed MW and 64% of deployed MWh respectively. Globally, as of January 2015, 1,100 MW and 2,523 MWh of grid storage have been deployed across 605 projects…Japan maintained its lead in installed energy storage capacity with 1,174 MWh. But the United States held global leadership in power and number of projects with 418 MW across 250 projects...Within the Li-ion battery chemistries, lithium iron phosphate (LFP) is the largest cathode deployed by MW [39%] and MWh [38.1%]…followed by nickel-manganese-cobalt (NMC), which is rapidly becoming the cathode of choice…Demand management [(376 MW and 1,335 MWh across 236 projects)] and renewable connected systems [(513 MW and 890 MWh across 261 projects)] are driving the primary grid storage applications…driven in the U.S. by time-of-use rates and tiered pricing…” click here for more
