University of Canterbury experts, including Professor Andy Nicol and Associate Professor David Dempsey, have contributed to an International Energy Agency (IEA) report on underground hydrogen storage technology. The report outlines the potential of underground hydrogen storage (UHS) as a key solution for balancing supply and demand, reducing carbon emissions, and enhancing energy security in the transition to renewable energy sources. It emphasizes the importance of understanding the current state of UHS technology, identifying challenges, such as safety and reliability, and assessing the economic viability for large-scale implementation. The report showcases advancements in efficiency and safety in UHS, highlighting the need for collaboration among countries, industries, and academia. Policy recommendations are provided to support the adoption of UHS, with a focus on addressing public and industry concerns regarding safety and reliability. The experts foresee UHS playing a significant role in the global energy landscape, driving economic benefits, job creation, and advancing the hydrogen economy over the next decade.
