In the last decade, increasing applications of information technology (IT) within power industry has become a significant reality. As distributed power networks are gaining importance and renewables are getting a bigger ratio within energy production, Smart Grid applications have become essential, especially due to the intermittent nature of renewable energy resources. Smart Grid is a sustainable energy system that measures, checks, and controls the generation, transmission, and consumption of electrical energy in grids on all voltage levels. Smart Grid experts are driving forward the development of effective communication and information technologies for the build-up of intelligent power supply networks. Examples of these are control systems for the realization of virtual power plants, intelligent consumer data acquisition systems, and smart distribution management systems. Fuel cell-based hydrogen electricity, in comparison to other renewable energy sources, is more stable and predictable. Yet hydrogen power and smart-grids have many application points, mainly as means of energy storage. This study claims that hydrogen energy and smart-grids could also engage through an appliance of IT managed metering of hydrogen power production. Smart metering and management of hydrogen fuel cells would enable advanced planning of short-to-mid-term power productions and thus foster use of hydrogen power within distributed networks, as local community or industrial applications.

This paper explores the crucial role of Underground hydrogen Storage (UHS) in the energy transition， presenting its types， applications， and distinct advantages. UHS offer large-scale storage capacity， extensive lifespans， and high safety levels， positioning them as an essential component of the energy transition to renewable resources. The development of UHS is primarily driven by policy initiatives， technological innovation， and economic incentives. The paper emphasizes the strategic goal of enhancing economic benefits by establishing a complete value chain for the hydrogen energy industry， propelling market-driven investment into hydrogen energy. The paper identifies China’s potential to lead in UHS due to its vast resources， technological advances， comprehensive industrial chain， and large industrial scale. hydrogen blending is a essential pathway to achieve net-zero emissions， utilizing existing natural gas pipeline networks and underground gas storage facilities for a smooth transition to green hydrogen. In conclusion， UHS， coupled with smart strategies like hydrogen blending， can effectively support the global shift towards cleaner， sustainable energy sources， contributing to global decarbonization and climate goals.
