Hydrogen Storage Opportunities in UAE: Potential Innovations and Advances

Abstract The paper aims to explore hydrogen storage opportunities in the UAE, focusing on the potential of salt domes in the region. It evaluates the technical, environmental, and sensitivity aspects of utilizing salt domes for large-scale hydrogen storage, aligning with the UAE's strategic goals for energy transition and decarbonization. This study employs a comprehensive approach that includes geological analysis, cavern design, and sensitivity assessment. The methodology involves identifying and characterizing suitable salt domes, designing storage caverns, and calculating their capacity. It also incorporates sensitivity analysis using Monte Carlo simulations to evaluate uncertainties and risks, alongside suggests advanced monitoring systems to ensure structural integrity and safety of proposed salt caverns. The analysis identifies several salt domes, such as Jebel Dhanna, Delma, and Sir Bu N'Air, as highly suitable for hydrogen storage. The designed caverns show significant storage capacity, with a median of 1144 caverns capable of storing approximately 503 million pounds of hydrogen. Sensitivity analysis highlights dome diameter and edge length as critical factors influencing storage capacity. Advanced monitoring systems and safety measures are proposed to mitigate risks associated with structural integrity and gas leakage. The findings support the UAE's strategic commitment to advancing hydrogen storage, contributing to energy security and the transition to a low-carbon future. This paper presents novel insights into the feasibility of using UAE salt domes for hydrogen storage, combining detailed geological analysis with advanced design and risk assessment techniques. It offers practical guidance for implementing large-scale hydrogen storage projects, contributing to the existing body of knowledge and supporting the UAE's leadership in the hydrogen economy.
