The article discusses the shift in focus from hydrogen as a universal climate fix to its key role in heavy industry, particularly in steel and ammonia production. Various setbacks in hydrogen projects in Australia and globally are highlighted, emphasizing the challenges in hydrogen's broad-scale adoption. However, the article points out the significant potential of using green hydrogen in heavy industry to reduce carbon emissions and reshape global supply chains. Research findings suggest that producing green iron with hydrogen in Australia and shipping it to Europe could be more cost-effective and environmentally friendly than traditional methods. The article also emphasizes the importance of industry hubs for efficient hydrogen production and usage. Challenges such as renewable energy variability, high production costs, and transportation issues are addressed, along with the need for substantial investments in hydrogen-compatible equipment. The Australian government's recent investments in green steel, hydrogen production, and tax incentives demonstrate a strong commitment to clean energy manufacturing, aiming to attract private investments and position Australia as a leader in the field.
