Australia is examining the potential to become a hub for hydrogen electrolyser manufacturing, with projections indicating significant economic benefits. By 2050, the industry could generate $1.7 billion in revenue and create 4,000 jobs, supplemented by $1.2 billion from installation services. The global electrolyser market's rapid growth presents an opportunity for Australia to establish advanced manufacturing capabilities. The country's existing manufacturers are leveraging research innovations, and a domestic pipeline of renewable hydrogen projects is driving local demand and supply chain advantages. To become a global leader, Australia must focus on strategic investments, sovereign capabilities, and the development of manufacturing hubs that tap into renewable energy advantages. Hydrogen electrolysers play a crucial role in the energy transition by enabling the production of clean hydrogen from water using renewable electricity. Australia's natural resources and established demand for hydrogen, coupled with supportive national initiatives, position the country well to capitalize on this emerging industry and contribute to global net zero goals.
