FaradionĀ and Phillips 66 to develop lower cost and higher-performing sodium-ion battery materials

Green Car Congress

Sodium-ion battery technology has an inherent advantage over other power-storage technologies because it uses low-cost materials that are sustainable and widely available. Current cell designs can provide gravimetric and volumetric energy densities comparable to lithium-ion and greatly in excess of lead-acid batteries. Earlier post.).

BMW i home energy storage system integrates 2nd-life i3 vehicle batteries

Green Car Congress

Following in-vehicle usage, the BMW i3 battery retains most of its original capacity, thus continuing to offer years of emissions free power storage and expanding the sustainability concept beyond the individual vehicle life. In 2014, BMW integrated high-voltage batteries into a stationary storage system in Hamburg.

Vattenfall contracts with BMW for up to 1,000 new 33 kWh Li-ion batteries this year for storage projects in wind farms

Green Car Congress

Pending on a final investment decision the largest battery storage will be built at the Vattenfall wind farm Pen y Cymoedd (230 MW) in South Wales—a 22 MW storage facility, which will help to support the stability of the country-wide power grid in the UK as part of the so-called EFR (Enhanced Frequency Response) service.
