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 the existing portfolio and the electricity grid. The UltraBattery^® technology, an entire new class of advanced lead-acid batteries invented by the CSIRO, 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 the UltraBattery^® to manage the ramp rate of renewable energy and to shift renewables output; · The outperformance of the UltraBattery^® 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. The demonstration projects have proven the ability of Ultra-Battery^® technology to combine renewable energy sources with a storage system, thus providing multiple benefits to making renewable resources reliable and dispatchable.
