A new report by CSIRO projects significant economic growth and job creation opportunities for Australia through its hydrogen electrolyser manufacturing (HEM) sector. By 2050, the sector could generate $1.7 billion in revenue and create nearly 4000 jobs. Australia is positioned as a key player in renewable hydrogen production, leveraging its strong starting position, innovative R&D capabilities, and renewable energy advantages. Driven by the need for timely action, the report highlights the potential for Australia to become a significant player in the global transition towards renewable hydrogen production. The report recommends a coordinated approach involving research, industry, and government to maximize the sector's potential. Strategies include aligned demand, building sovereign capabilities, and promoting strategic manufacturing hubs. Additionally, the report identifies growth prospects in electrolyser installation services, projecting $1.2 billion in revenue and 1000 jobs by 2050. Dr Patrick Hartley underscores the window of opportunity Australia has to capture a portion of the global electrolyser market, emphasizing the benefits of developing a geographically aligned supply chain. The report stresses the economic and environmental benefits Australia could gain by seizing this opportunity.
