The University of the Sunshine Coast has installed an experimental water battery that has cut their energy costs by $100 million.

Standing three stories high, the battery will aid the university in reaching their goal of being carbon neutral by 2025, with the battery already reducing reliance on the energy grid by 40 percent.

The giant battery harnesses 6,000 solar panels to cool water used in the university’s air conditioning systems.

Chief Operating Officer Scott Snyder says, “…by forming a partnership with [resource management company] Veolia, we were able to negotiate a 10-year plan that suited us both and delivered major energy savings to the University.”
