Australian Maltings Plant Geothermal Heating Feasibility

JRG Energy assessed a geothermal heating system designed to deliver ~10MW of baseload thermal energy for Boortmalt’s Perth maltings plant — its highest heat demand Australian facility. The system targets the plant’s dominant low-temperature heat demand (~60°C), achieving an estimated 42% emissions reduction and over 339,000 tonnes of CO₂ savings across a 30-year operating life. The study confirmed commercial viability and integration with existing kilning systems using proven heat exchange technology.
