South East Water and RMIT University have developed an innovative method for producing green hydrogen from solar energy and recycled water, winning the prestigious 2024 Water Minister's Climate Innovation Challenge. This project, which received $113,000 in funding from the Victorian Government, involves utilizing a floating modular platform to convert solar radiation and recycled water into green hydrogen and valuable oxidants like ozone and hydrogen peroxide. The initiative aims to tackle climate challenges by reducing carbon emissions, addressing energy issues, and enhancing water quality. South East Water Managing Director Lara Olsen emphasized the importance of collaboration and sustainability in achieving net-zero goals. Dr. Li Gao, the Project Lead with joint appointments at RMIT University and South East Water, highlighted the significance of industry partnerships in translating research discoveries into practical benefits for society. The project, supported by additional funding from South East Water and RMIT University, plans to develop a small-scale prototype for future full-scale implementation in Victorian water utilities. The floating hydrogen production system is designed to be scalable and adaptable, suitable for various water bodies. The success of this world-first technology underscores the potential of the water industry to lead in addressing climate challenges through innovation and collaboration.
