Special Issue Information

Dear Colleagues,

Hydrogen stands at the forefront of the global transition toward sustainable and decarbonized energy systems. As a clean, versatile energy carrier with the potential to decouple energy production from carbon emissions, hydrogen offers transformative opportunities across multiple sectors—from industry and transportation to power generation and storage. Recent years have witnessed remarkable advancements in hydrogen technologies, driven by the urgent need to meet climate targets, enhance energy security, and foster economic resilience.

This Special Issue "Advances in Hydrogen Production, Storage, and Utilization" aims to provide a comprehensive platform for the dissemination of cutting-edge research, innovative technologies, and critical insights across the hydrogen value chain. Contributions are invited that span fundamental studies and applied research, covering topics such as novel production pathways (including, but not limited to, electrolysis, photochemical, thermochemical, and biological processes), advanced storage materials and systems, and emerging applications in fuel cells, industrial processes, and integrated energy networks.

We particularly welcome interdisciplinary approaches that bridge materials science, engineering, chemistry, and policy perspectives, as well as studies that address the economic, environmental, and social dimensions of hydrogen technologies. By gathering a diverse range of high-quality research articles, reviews, and case studies, this Special Issue seeks to foster dialogue, inspire innovation, and accelerate the deployment of hydrogen solutions at scale.

We warmly invite researchers, practitioners, and policymakers to contribute their latest findings and perspectives to this Special Issue and join us in advancing the frontiers of hydrogen science and technology.

This study presents the design and techno-economic comparison of two standalone photovoltaic (PV) systems, each supplying a 1 kW critical load with 100% reliability under Cairo’s climatic conditions. These systems are modeled for both the constant and the night load scenarios, accounting for the worst-case weather conditions involving 3.5 consecutive cloudy days. The primary comparison focuses on traditional lead-acid battery storage versus green hydrogen storage via electrolysis, compression, and fuel cell reconversion. Both the configurations are simulated using a Python-based tool that calculates hourly energy balance, component sizing, and economic performance over a 21-year project lifetime. The results show that the PV/H2 system significantly outperforms the PV/lead-acid battery system in both the cost and the reliability. For the constant load, the Levelized Cost of Electricity (LCOE) drops from 0.52 USD/kWh to 0.23 USD/kWh (a 56% reduction), and the payback period is shortened from 16 to 7 years. For the night load, the LCOE improves from 0.67 to 0.36 USD/kWh (a 46% reduction). A supplementary cost analysis using lithium-ion batteries was also conducted. While Li-ion improves the economics compared to lead-acid (LCOE of 0.41 USD/kWh for the constant load and 0.49 USD/kWh for the night load), this represents a 21% and a 27% reduction, respectively. However, the green hydrogen system remains the most cost-effective and scalable storage solution for achieving 100% reliability in critical off-grid applications. These findings highlight the potential of green hydrogen as a sustainable and economically viable energy storage pathway, capable of reducing energy costs while ensuring long-term resilience.
