The Australian Renewable Energy Agency (ARENA) has allocated $3 million to support Barwon Water's Green Oxygen for Wastewater Treatment project in Geelong. This project involves utilizing pure oxygen captured from an electrolyser at a new hydrogen refuelling station to enhance the efficiency of Barwon Water's wastewater treatment process. By incorporating oxygen-enriched air, the project aims to significantly reduce energy consumption and operating costs in wastewater treatment. The collaboration between ARENA, Barwon Water, and Viva Energy highlights the potential for hydrogen producers and water utilities to work together towards decarbonisation objectives. Barwon Water's strategic initiatives, including the use of renewable energy sources and hydrogen-powered vehicles, demonstrate a commitment to achieving net zero emissions by 2030. The project also emphasizes the importance of circular economies, where resources like recycled water and byproduct oxygen are utilized in a sustainable manner. Through partnerships with companies like HDrive and Viva Energy, Barwon Water is pioneering innovative solutions for more sustainable wastewater treatment and transportation practices in Victoria.
