Hydrogen fuel is gaining attention as a solution for carbon emission reduction, leading to increased exploration of underground storage options. While storing hydrogen in high volumes underground is cost-effective, its small molecular size poses challenges compared to traditional fuels. Salt caves and other geological formations are potential sites for underground hydrogen storage (UHS), but issues like leakage prevention and explosion risks must be addressed. Zhang et al.'s research reviews the current state of UHS, emphasizing the need for advancements in material development and the use of AI for real-time monitoring. They stress the importance of a multidisciplinary approach involving various fields to ensure the safety and success of UHS facilities. Establishing comprehensive solutions and robust safety management frameworks is crucial for the long-term operation of UHS sites. The article provides valuable guidelines for engineers and researchers involved in UHS projects, aiming to drive innovations in hydrogen storage and contribute to achieving net-zero carbon emissions goals.
