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.

Forecast: Lithium Ion Batteries for Electric Vehicles to Approach $8 Billion in Sales by 2015

Green Car Congress

According to a new report from Pike Research, a rapidly growing global market for electrified vehicles—particularly plug-in hybrid and battery-electric vehicles—will create a Li-ion transportation battery industry with nearly $8 billion in sales worldwide by 2015, up from $878 million in 2010.

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

As the percentage of electricity supply from wind and solar increases, grid operators will need to employ strategies and technologies, including energy storage, to balance supply with demand given the intermittency of the renewable supply. When demand is high, the water is released through turbines that generate electricity.

PNNL team finds that new electrolyte mix increases energy storage capacity of vanadium redox batteries by 70%

Green Car Congress

Our small adjustments greatly improve the vanadium redox battery. And with just a little more work, the battery could potentially increase the use of wind, solar and other renewable power sources across the electric grid. —lead author and PNNL chemist Liyu Li.

Pike Research forecasts worldwide grid energy storage spending to reach $22B by 2021, down from 2010 forecast of $35B

Green Car Congress

Electric grids require balance in order to function properly. Energy storage technologies represent an alternative to traditional grid management using generation assets such as natural gas peakers to balance the grid by adding power to it. Thus, the ancillary services forecasts are based on a value of power ($/kW).

In Norway, Asko begins piloting use of hydrogen fuel-cell trucks

Green Car Congress

Electricity generated by solar panels installed across nine thousand square metres of roofing at Asko’s regional warehouse is being used to split water, producing emissions-free hydrogen fuel and oxygen. The aim here is not to use hydrogen for all goods transport. In addition to solar, Asko is a major industrial wind power producer.
