Professor Ranjith Pathegama Gamage and his team at Monash University's Deep Earth Energy Research Lab are leading innovative research into large-scale hydrogen storage solutions. They are exploring the use of depleted gas fields and engineered rock caverns as 'hydrogen vaults' to overcome the challenge of safe and scalable hydrogen storage. This research is crucial for the transition to clean energy, offering a solution for energy security and stable storage during surplus periods. Additionally, the team is investigating methods to produce hydrogen from natural systems with lower environmental impact. Associate Professor Stuart Walsh emphasizes the economic opportunities of the energy transition but warns of the need for swift action to stay competitive globally. The research at Monash University is positioning Australia as a leader in hydrogen technology and storage innovation, with implications for global clean energy infrastructure and energy security.
