Default Another Vanadium based mass storage device

Readers might remember my earlier post: Re VRBs and China... Prudent Energy, a clean energy company, has finalized the installation of a 1MWh Vanadium Redox Battery, or VRB, energy storage system, sized at a rated power 500kW and a peak power of 750kW pulse capability for the China Electric Power Research Institute in Zhangbei, Hebei province in northern China.

Today's announcement of a second very large VRB for California could be taken as confirmation that Vanadium Redox batteries are going to play a strong part in green energy storage...

BETHESDA, Md., March 9, 2011 /PRNewswire/ -- Prudent Energy, the designer, manufacturer, and integrator of the patented Vanadium Redox Battery Energy Storage System (VRB-ESS?), has been awarded a grant from the California Public Utilities Commission (CPUC), in cooperation with SunPower Corp. (Nasdaq: SPWRA, SPWRB), Pacific Gas and Electric, KEMA, and Sandia National Laboratories of the U.S. Department of Energy (DOE), to build and operate a VRB-ESS? with SunPower's photovoltaic (PV) systems.


Prudent Energy's clean energy storage project is a welcome addition to the CPUC's California Solar Initiative (CSI) Research, Development, Deployment and Demonstration (RD&D) Plan. Prudent's "flow battery" system works like a rechargeable fuel cell, where chemical energy is converted to electrical energy at a moment's notice. In particular, Prudent's VRB-ESS? will help SunPower's commercial customers reduce their energy costs by drawing on stored power during those few hours each day when the sun goes down, but electricity usage and rates remain high. The system is thus expected to substantially improve the economics of distributed solar energy technologies.



"We are very excited to join SunPower, the CPUC, DOE, PG&E, and our other partners in this project," said Jeff Pierson, Prudent Energy's senior vice president. "Prudent's Vanadium Redox Battery is an excellent fit in the distributed solar market. We expect to give California ratepayers what they want most "major savings on their electric utility bills."


Prudent Energy is responsible for a 100 kW, 300 kWh turn-key VRB-ESS?, scheduled for completion this fall. The location has not been announced. The project comes on the heels of another recent announcement that Prudent Energy was building and operating a 600 kW, 3.6 MWh VRB-ESS? facility at Gills Onions in Oxnard, California.

Australian ASX listed companies control a large amount of the world's Vanadium resources... I've collated some information here.

VRB is the Energy storage system and it it quick time installation in south Africa. This battery is rechargeable type so you can use again. Thanks for sharing nice and important information regarding VRB.
