This Australian-first green hydrogen project is being delivered for WA’s regional power provider, Horizon Power, to test the technological and commercial viability of renewable hydrogen as a baseload power source. ENGV was engaged by fellow Pacific Energy subsidiary, Hybrid Systems Australia, to supply and install world-leading hydrogen equipment in the system, including: - Two C30 Nel hydrogen electrolysers in a modified 40' sea container - A two-stage PDC diaphragm compressor in a 10' container - A 280kg hydrogen 20' MEGC container - A 100kW fuel cell - A 20' modified sea container, including DI/RO water treatment for electrolysers - System air compressors and an external water-cooling unit for the electrolysers and fuel cell As a part of the project, Hybrid Systems Australia constructed a 704kW solar farm that generates the renewable energy required to produce the hydrogen. The plant, which produced its first hydrogen in October 2022, is expected to produce renewable energy equivalent to the average power demands of 100 households, or about 20 per cent of Denham’s residential and business power needs, and will offset approximately 140,000L of diesel annually. The plant was officially opened by WA’s ministers for Energy and Hydrogen Industry in November 2022 and is expected to be fully operational in early 2023. The project was funded by Horizon Power, the Western Australian State Government and the Australian Renewable Energy Agency (ARENA).
