The state government of Western Australia has released a report detailing the lessons learned from the commissioning and operation of the first-of-its-kind solar and green hydrogen microgrid in Denham, a coastal town north of Perth. The microgrid consists of a 704 kW solar farm, electrolysers, storage systems, and a fuel cell, all aimed at utilizing renewable energy sources efficiently. The project aims to generate 526 MWh of renewable energy per year, with 13,000 kilograms of green hydrogen produced annually to reduce diesel consumption by 140,000 litres. Challenges faced by the contractor included developing deliverables from scratch due to the project's unique nature. The successful development of a mature control program to manage the dispatch of electrolysers was crucial for commissioning success. The report emphasizes that the purpose of the system is to demonstrate the viability of hydrogen storage systems to store excess renewable energy and return it to the grid, thereby supporting the energy transition. Western Australia's Acting Energy Minister highlighted the breakthrough potential of hydrogen as a backup for renewable energy during low generation periods and its role in the state's energy transition. The report concludes that by displacing diesel with hydrogen, the technology can benefit regional communities connected to microgrids. Horizon Power will continue to monitor and improve the Denham plant over the next year, sharing the knowledge gained with the industry to advance renewable energy and hydrogen integration.
