A Power Quality and Energy Storage Cube for the Residential Market
The future of sustainable power sources will reach peak efficiency when power storage and redistribution is available to every household. Axion Power International has made a first step towards such a future, in conjunction with the Rosewater Energy Group based in Fort Lauderdale, Florida, as they plan to create a variety of energy storage and conversion products for the high-end residential market.
The two companies signed a Letter of Intent which memorializes a strategy to create a series of technologies based on Axion’s advanced lead-carbon PbC batteries and energy storage systems.
The project calls for the incorporation of Axion Power’s PbC batteries, and technology know how, into a product package that offers distortion-free secure home power; an ability to store energy from renewable sources and from the electric grid; an ability to sell energy back to the electric grid; an opportunity to protect some, or all, of the residential circuitry and to prioritize these circuits.
The PbC battery referenced are hybrid batteries made by Axion that combine the standard lead acid battery positive electrode and a supercapacitor negative electrode that is made of activated carbon. The whole scientific understanding of the differences between standard batteries and Axion PbC batteries can be found here, but in short, the PbC battery experiences fewer “acid concentration swings from the charged to discharged state which reduces grid corrosion on the positive electrode and leads to longer life of the positive electrode.”
“We have seen the value of PbC technology, as a secure energy storage source, while working with Axion CUBE designs, and other products, over the past two years,” said Rosewater Energy Group Managing Director Joseph Piccirilli. “We believe this technology has tremendous value for entertainment technologies, and a range of home upgrades that will enable residential owners to have a previously unattainable sense of both power quality and energy security in their homes.”
The basic premise behind the battery is the same at any level. Axion recently commissioned a .5MW/.25MWH PowerCube at its Clover Lane plant in November of 2011, but the same building block technology is used in the construction of the smaller cubes as well; 100kW all the way down to 10kW.
The residential cube, a 10kW/12kWh battery, will provide home owners with power quality, uninterrupted power back up, and the ability to store energy from renewable sources such as solar and wind. In addition, the unit has the ability to be grid connected, so that, on either a regular or an occasional basis, a home owner can participate in demand response and/or power curtailment.
Axion Power Chairman and CEO Thomas Granville commented: “We are very pleased to be expanding our work with Rosewater Energy Group. The high-end residential market is a natural for this technology, because it allows homeowners to enjoy 100% clean undistorted power for all applications, including home entertainment systems. It can also provide power during blackout conditions and can be fully grid tied.”
“We believe this product line can quickly become the gold standard for upscale homes,” Granville added. “We look forward to kicking off the product line at the CEDIA Expo right after Labor Day, and believe that Rosewater Energy, with their previous long history selling into our target market, is the right distributor for our residential energy product.”
