Underground Hydrogen Storage: Prospects, Opportunities, and Challenges presents a comprehensive analysis of the technical and economic aspects of underground hydrogen storage. In addition to providing a detailed examination of the fundamentals, properties, storage options, reaction kinetics, modeling, and economics of underground hydrogen storage, the book offers pragmatic solutions to the demand-supply gap caused by conventional hydrogen storage systems and intermittency challenges associated with renewable energy sources. In addition, users will find this to be a foundational introduction to underground hydrogen storage and a detailed review of the properties of hydrogen.Other sections are dedicated to depleted gas reservoirs, oil reservoirs, aquifers (including saline aquifers), salt caverns, coal mines, lined hard rock caverns, and refrigerated mined caverns. Influencing parameters such as permeability, density and viscosity, interfacial tension and surface tension, wettability, capillary pressure, absorption, desorption, solubility, and diffusivity are also covered as are reaction kinetics, including methanogenesis, acetogenesis, sulphate reduction, and iron reduction, and much more. - Provides the latest advances in underground hydrogen storage; technologies, options, properties, modeling, and economics - Examines the prospects, challenges, and opportunities for underground hydrogen storage as part of the hydrogen economy - Presents a detailed evaluation of potential underground hydrogen storage sites across the globe - Includes dedicated chapters on the reaction kinetics of hydrogen – methanogenesis, acetogenesis, sulfate and iron reduction – within the context of different storage options
