The University of Canterbury experts, Professors Andy Nicol and David Dempsey, have played a crucial role in contributing to an International Energy Agency (IEA) report that delves into the advancements and future potential of underground hydrogen storage (UHS) technology. The report emphasizes the growing need for sustainable and efficient energy storage solutions as the world transitions towards renewable energy sources. Underground hydrogen storage offers a promising method to balance energy supply and demand, reduce carbon emissions, and enhance energy security. Prof. Nicol and Assoc. Prof. Dempsey stress the importance of teamwork in decarbonizing economies and energy systems to combat the adverse effects of climate change. The detailed analysis provided in the IEA report compares the latest technological advancements in UHS with previous methods in terms of efficiency and safety. It also explores the environmental and economic impacts of widespread adoption of UHS technology, highlighting its potential to support renewable energy integration and contribute to a low-carbon future. Prof. Nicol's visit to Austria showcased an early pilot project for storing hydrogen underground, demonstrating the feasibility of the concept. The report underscores the significance of understanding the current state of UHS technology and addressing challenges for its large-scale deployment. Safety, reliability, and economic viability are crucial aspects that require extensive testing and validation. The collaboration among countries, industries, and academia is deemed essential to efficiently study and deploy UHS technologies. Furthermore, the report outlines the economic benefits of UHS technology, including job creation and energy cost savings, emphasizing the role of companies in driving its adoption. Prof. Nicol and Assoc. Prof. Dempsey foresee UHS evolving as a key component in the global energy landscape in the upcoming decade, with increasing adoption and technological advancements as the hydrogen economy expands. The policy recommendations provided in the report aim to support the adoption of UHS and acknowledge regions and countries leading the way in implementing this innovative technology.
