PNNL study outlines requirements for grid storage, reviews four electrochemical energy storage systems: vanadium redox flow, Na-beta, Li-ion and lead-carbon

Green Car Congress

published in the ACS journal Chemical Reviews , reviews in detail four stationary storage systems considered the most promising candidates for electrochemical energy storage: vanadium redox flow; sodium-beta alumina membrane; lithium-ion; and lead-carbon batteries. Among the most important factors are capital cost and life-cycle cost.

Pilot Project Sends Kelp–and Carbon–to the Seafloor

Cars That Think

At daybreak, the cranks pull the ring back up to the surface to soak up sunlight and carbon dioxide. The Climate Foundation , the Seattle-based company behind the project, has found that this deep cycling makes kelp grow three times as fast as it can when kept in shallow waters, as seaweed farmers do now.

Ioxus Developing Higher Power Density Ultracapacitors

Green Car Congress

Ioxus says that the power density of its 100F carbon-carbon ultracapacitor solutions is 2x over that of competitive comparable 100F cells. Ioxus makes carbon-carbon ultracapacitors—i.e., The use of the module also prevents the battery from deep cycling, extending the life of the battery.

Graphene oxide-sulfur (GO-S) nanocomposite cathodes for high-capacity, stable cycling lithium sulfur batteries

Green Car Congress

A team from Lawrence Berkeley National Laboratory and Tsinghua University (China) have synthesized graphene oxide-sulfur (GO-S) nanocomposite cathodes and applied them in lithium/sulfur cells to show a high reversible capacity of 950-1400 mAh g -1 and stable cycling for more than 50 deep cycles at 0.1C (1C = 1675 mA g -1 ).

Axion supplying PbC batteries to Norfolk Southern for all-battery switcher and working on line-haul hybrid locomotives; micro-hybrid and stationary expansion

Green Car Congress

In April, Axion Power International Inc received an order from Norfolk Southern Corp (NS) for PbC lead-carbon batteries for use in an all-battery-powered switcher locomotive. PbC batteries are multi-celled asymmetrically supercapacitive lead-acid-carbon hybrid batteries. The battery-electric NS-999, “under the long hood”. Source: NS.

Industry study finds lead-acid to remain most wide-spread automotive energy storage for foreseeable future; new chemistries continue to grow

Green Car Congress

Advanced lead-based batteries (AGM and EFB technologies) are installed to meet extra requirements in start-stop and basic- micro-hybrid vehicles, due to their increased charge recoverability and higher deep-cycle resistance. In these applications, they are currently the only technology available for the mass-market.
