Solar Energy System
Apart from captured rainwater, the farm’s water supply is provided by water pumped from a spring-fed dam (called the ‘Farm D’ dam).
To reduce carbon emissions, a solar array and battery system has been installed to support the operation of the Farm D pumping station. The solar photovoltaic (PV) system generates renewable electricity by converting energy from the sun. A zinc-bromine flow battery is used for energy storage.
Zinc-bromine Battery Storage
A zinc-bromine flow battery is a rechargeable battery system. The electrochemical mechanism is the same as a lithium-ion battery, but this battery has a water-based electrolyte.
Compared to lithium-ion batteries, this technology is ideal for an agricultural site because of its negligible decline in performance over ten years and stable storage capacity.
The size and weight make them well suited outdoor installation. The disadvantages of this technology can include higher cost.
