Australia's first renewable hydrogen microgrid in Denham, Western Australia, has been successfully commissioned after delays caused by COVID-19. The microgrid integrates hydrogen technology into an existing off-grid hybrid system, reducing reliance on diesel and incorporating a 348-kW hydrogen electrolyzer and a 100-kW fuel cell. The system, managed by Horizon Power, is expected to offset 37,000 gallons of diesel fuel annually and power 20% of Denham's residences and businesses. The Denham project is part of Horizon Power's efforts to explore the viability of hydrogen energy storage systems as alternatives to diesel generators. The WA government invested $5.7 million in the project, aiming to demonstrate the potential for hydrogen in remote microgrid sites. The initiative also aligns with the state's transition to renewable energy, emphasizing hydrogen's role in creating jobs and business opportunities. The report released by Horizon Power and the WA government highlights key learnings from the project, focusing on technology, costs, regulatory requirements, and community sentiment. By monitoring the system for a year, the project aims to gather insights for future improvements and to guide the implementation of renewable hydrogen projects across WA and the nation. The success of Australia's first renewable hydrogen microgrid reflects a broader global trend, as seen in the U.S., where companies like Vertiv and Plug Power are also investing in hydrogen-powered microgrid projects, showcasing the increasing interest and potential for hydrogen in the renewable energy sector.
