In energy storage, fantastic claims of game-changing technologies launch, peak and fall rapidly – only rarely does an actual product result. In a press release, ERRA Incorporated of San Antonio, Tex., announced their acquisition of a set of rights and patents for a “breakthrough battery technology” to be marketed as the YESS (Your Energy Storage Solution) Battery from ERRA, Inc. The press release made no mention of the battery’s chemistry, only that it was “Simply the most cost effective energy storage battery module on the planet!” If nothing else, we were curious.
With a little digging, we discovered that ERRA had bought the rights to some important innovations in nickel-hydrogen (Ni-H2) batteries. Ni-H2 is, as the press release indicated, is the same battery tech that has been powering satellites for the last 30 years or so. Not remembering when Sputnik was launched, it can only say that the batteries have been working continuously. NI-H2 can withstand upwards of 20,000 charge-discharge cycles, can be 100 percent discharged, recharged and then used as if nothing happened and still have a zero self discharge rate. The reason they haven’t been used in cars before? Energy per kilogram, the Hindenburg and weight.
