Shifting Solar to Peak Hours
The Australian Renewable Energy Agency (ARENA) has announced a series of trials for long-duration energy storage (LDES) batteries aimed at remote and regional customers. Western Australian energy provider Horizon Power will lead the initiative, testing novel battery technologies to shift midday rooftop solar generation to peak evening hours. This transition is critical for areas that have historically relied heavily on expensive and polluting diesel generators.
Zinc-Bromine and Molten Salt Deployments
In the remote town of Nullagine, Horizon Power will install a 100 kW / 400 kWh Redflow zinc-bromine flow battery on a local microgrid. These non-flammable units are specifically designed to withstand extreme heat conditions, ensuring reliable operation in harsh outback environments. Meanwhile, the town of Carnarvon will see the installation of a 250 kW / 1,450 kWh BASF molten salt battery. Additionally, a BASF sodium sulphur battery will be deployed in Carnarvon, marking the first of its kind in Australia to connect to a regulated network. Both BASF systems utilize inexpensive, non-toxic salt and sulfur chemistry, ensuring longer-lasting supply and extreme heat safety.
Building on Vanadium Success
This new wave of trials builds upon Horizon Power's previous success in 2023, when it became the first Australian energy utility to purchase a vanadium flow battery from VSUN Energy for an LDES pilot in Kununurra. By utilizing locally produced Western Australian vanadium electrolyte, that project laid the groundwork for the current diverse technology trials.
These trials represent a crucial step in decarbonizing remote microgrids, proving that diverse LDES chemistries can reliably replace diesel generation in harsh environments.
The insights gained from these deployments will inform future grid-scale strategies across Australia's vast regional networks.
