When will the Cellennium products/systems be available for sale?
The vanadium battery/fuel cell system is still under development. The first commercial system was placed into operation December 2008 at Horseshoe Point Resort and Country Club in Cholburi, Pattaya, Thailand. Several ongoing demonstration projects, will continue this year, including 10kW and 50kW systems for stand-alone and grid-connect PV applications, as the factory tools up for mass production.
Who were the original inventors of the vanadium redox flow battery?
Albero Pellegri and Placido Spaziante were the original pioneers of the vanadium redox flow battery. Their patent was granted in 1978 in Great Britain ( GB 2 030 349 A 10) , France (FR2,431,196 ), Germany (2,927,868), Canada (CA 1,143,432) and Japan (55024389).
What will be the power rating of the smallest standard systems?
The smallest (commercial) systems will start at about 3 kW.
How much will the vanadium fuel cell systems cost?
Pricing has not been set, but we expect our systems to be very price competitive with conventional lead-acid battery system complete with charger and power inverter.
What is the normal operating temperature regime?
The battery can do fine within a wide range of temperatures. Typical operating temperatures range between 50 and 80 degrees Celsius.
How does the power required for pumping electrolytes compare between the Squirrel series flow design and conventional parallel flow design?
For the Squirrel design power required for pumping is less than 1% of the rated power of the battery. This performance figure has been already verified by SGS (Singapore). The power required for pumping by other redox flow battery designs (i.e. parallel flow) is on the order of 8% to 15% of the rated power. The key features of our design, cell-to-cell flow and electrolyte channels, allow our systems to operate at flow rates at least 20 times lower, with lower pressure, than conventional parallel flow designs.
