UltraBattery® Research

UltraBattery® has been proven to perform better than competing, conventional valve-regulated lead-acid (VRLA) batteries in tests conducted by independent laboratories, as well as by East Penn Manufacturing, Furukawa and Ecoult.

Sandia National Laboratories

Tests by Sandia National Laboratories in the United States show that UltraBattery® performs for much longer than conventional VRLA batteries in utility cycling and photovoltaic hybrid energy applications. Read more

Sandia National Laboratory UltraBattery® Cycle Test

Sandia National Laboratory UltraBattery® Cycle Test

In a test of wind farm energy smoothing application, Ultrabattery® was capable of about 13 times as many high-rate, Partial State of Charge cycles than a conventional, absorbed glass mat (AGM) valve-regulated lead-acid (VRLA) battery. The UltraBattery® could also be cycled more than 10 times as often as the AGM battery between recovery charges. Read more

ALABC

The Advanced Lead Acid Battery Consortium (ALABC) has demonstrated the durability of UltraBattery® in the high-rate, Partial State of Charge operation of a hybrid electric vehicle. The Honda Civic demonstration car had comparable miles per gallon performance as the same model powered by nickel metal hydrid batteries, but at a significantly lower cost. Read more

Furukawa Battery

In hybrid electric vehicle tests, the UltraBattery® has double the cycle life of existing lead storage batteries. In tests of a stationary application for an electricity smart grid, UltraBattery is highly energy efficient, has a long cycle life, and has superior recovery characteristics when operating in a Partial State of Charge.

EPRI

5-Year Update of EPRI (Electric Power Research Institute) Smart Grid Demonstration Initiative: UltraBattery energy storage was used as part of the PNM Prosperity Project for solar smoothing and shifting and has been shown to be able to smooth intermittent renewable generation to create a firm, dispatchable resource. As well as in EPRI’s full case study on the project, the UltraBattery installation is highlighted as a significant project in EPRI’s “Smart Grid Demonstration Initiative 5-Year Update”, an international project to demonstrate the viability of smart grid technologies.

The PNM Prosperity Project shows how significant energy shifting and smoothing can be on the grid, particularly in altering the profile of grid scale renewables. UltraBattery smoothing was applied to the output of a 500 kW New Mexico solar PV array, where tests had measured ramp rates of 136 kW per second as solar energy was lost to cloud cover. Such large fluctuations in energy output become unsustainable as renewable penetration increases. UltraBattery technology is successfully controlling the PV output and demonstrating the viability of combining PV with a battery-based energy storage system. Read more

Integrating Renewables into the Grid: Applying UltraBattery® Technology in MW Scale Energy Storage Solutions for Continuous Variability Management

Electricity providers are increasingly faced with the challenge to integrate variable renewable generation with their existing portfolios and into the electricity grid. UltraBattery® technology now allows the continuous management of variability and shifting of energy, crucial for the large scale integration of renewables. The UltraBattery® has already been successfully implemented globally in several MW scale energy storage projects to demonstrate:

  • The endurance and longevity of UltraBattery® technology to manage the ramp rate of renewable energy and to shift renewables output;
  • The superior performance of UltraBattery® cells in the provision of regulation services over incumbent gas peakers often used for regulation services; and
  • The potential to reduce the cost of each MWh of storage used to control renewable energy variability.
