Hydrogen, once hailed as a universal climate solution, has faced setbacks in Australia. The South Australian government redirected funds from a hydrogen plant to aid Whyalla steelworks, reflecting a shift towards heavy industry reliance on hydrogen. Despite companies like Fortescue and Woodside scaling back projects, there is optimism for hydrogen in heavy industries like steel manufacturing and ammonia production due to its potential to significantly reduce emissions. Research indicates that utilizing green hydrogen for these industries could lead to cost savings and emission reductions. Industry hubs producing hydrogen near consumption sites are seen as a practical solution, reducing transportation costs and improving efficiency. While challenges like renewable energy intermittency and high production costs persist, government support through investments and tax incentives is accelerating the transition to green steel and hydrogen production. The investment in green steel and hydrogen in Australia not only promises environmental benefits but also presents economic opportunities by reshaping global supply chains and cutting carbon emissions.
