The Yara Pilbara Renewable Ammonia Feasibility Study is for a demonstration-scale renewable hydrogen and renewable ammonia production and export facility on the Burrup Peninsula, Western Australia.
Yara Pilbara (Yara) is the world’s leading ammonia and fertiliser production company with approximately 20 per cent market share of the global ammonia trade. Yara’s Burrup Peninsula facility currently produces ammonia by using natural gas as a feedstock for its steam methane reforming process, which produces fossil-fuel based hydrogen. The hydrogen is then used to feed an ammonia synthesis process to produce ammonia. Yara is investigating producing renewable hydrogen to feed its ammonia production process, which will reduce emissions produced by the facility.
In collaboration with global energy company ENGIE, the Yara Pilbara Renewable Ammonia Feasibility Study will investigate the feasibility of producing renewable hydrogen via electrolysis powered by onsite solar PV. Yara’s objective is that approximately three per cent of the hydrogen blend will be renewable hydrogen. The blended hydrogen will subsequently be converted to ammonia and sold for further processing into domestic and international markets. The feasibility study will also investigate using seawater for the electrolyser.
The renewable hydrogen produced will displace 30,000 tonnes per year of hydrogen that Yara currently derives from fossil fuels. The study will be the first step on the path to achieving commercial scale production of renewable hydrogen and ammonia for export. In the long term, Yara is aiming to produce hydrogen and ammonia entirely through renewable energy. This approach will allow Yara to avoid any major augmentation to the existing plant and therefore minimise the cost and time needed to produce renewable ammonia.
This project has the potential to ‘unlock’ the value of vast areas of vacant Pilbara land by supporting the development of a new industry that captures solar energy for conversion to hydrogen and other valuable products.
