A recent report from CSIRO, Australia's national science agency, highlights a lucrative opportunity in the country's hydrogen electrolyser manufacturing (HEM) sector. Projections indicate that by 2050, the sector could generate $1.7 billion in revenue and create nearly 4000 jobs. The report emphasizes the importance of Australia leveraging its renewable energy advantages and R&D capabilities to become a key player in global renewable hydrogen production. Strategies recommended in the report include aligning with adjacent clean energy opportunities, exploring international partnerships, and establishing strategic manufacturing hubs to maximize the sector's potential. In addition to manufacturing, there is also significant growth potential in electrolyser installation services, with projections of an additional $1.2 billion in revenue and 1000 jobs by 2050. Dr. Patrick Hartley of CSIRO's Hydrogen Industry Mission highlighted the opportunity for Australia to capture a share of the global electrolyser market by developing a geographically aligned supply chain. With the right approach, Australia could reap economic and environmental benefits from owning a significant portion of the electrolyser market, further solidifying its position in the clean technology manufacturing sector.
