Australia's national science agency, CSIRO, has released a report showcasing the immense opportunity for the nation in the hydrogen electrolyser manufacturing (HEM) sector. The report foresees significant growth, estimating $1.7 billion in revenue and the creation of nearly 4,000 jobs by 2050. This initiative aligns with the global trend towards renewable hydrogen production, positioning Australia as a key player. CSIRO emphasizes the urgency of seizing this opportunity to build a sustainable industry that can contribute long-term value to the economy and enhance energy security through the development of sovereign manufacturing capability. The report underlines the need for collaboration between various stakeholders to fully realize the potential of the HEM sector, advocating for strategies like aggregated demand, global partnerships, and strategic manufacturing hubs. Additionally, the report identifies an extra $1.2 billion revenue opportunity and the generation of 1,000 new jobs in electrolyser installation services by 2050. Dr. Patrick Hartley of CSIRO emphasizes the importance of swift action to establish Australia's presence in the global electrolyser market, highlighting the advantages of a geographically aligned supply chain. By leveraging renewable energy resources and research capabilities, Australia can solidify its position in the rapidly expanding hydrogen sector and reap economic and environmental benefits.
