Australia and Japan are looking to leverage their expertise in renewable energy and technology to unlock the potential of a green hydrogen value chain. A joint report developed by the Australian Academy of Technological Sciences and Engineering (ATSE) and the Engineering Academy of Japan (EAJ) outlines a vision for producing, storing, and exporting renewable hydrogen by 2050. The report identifies key opportunities in chemical production, steelmaking, and shipping fuels, highlighting green hydrogen as a critical input for decarbonizing heavy industry. However, challenges such as infrastructure shortfalls, limited-scale production projects, and financing constraints pose significant bottlenecks. To address these issues, the report recommends focusing on reducing costs of electrolysers and renewable energy generation, securing financing for projects, and establishing joint R&D centers. Despite these challenges, experts are optimistic about the potential of Australian and Japanese innovation working together. The report suggests aligning certification frameworks, investing in workforce training, and bringing together stakeholders from industry and academia to drive the green hydrogen agenda forward.
