Special Issue Information

Dear Colleagues,

We are sincerely grateful to all authors, reviewers and readers for their valuable support of the first edition of our Special Issue, Advances in Hydrogen Production, Storage, and Utilization. We are now pleased to announce the launch of the 2nd edition of this topic.

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 (2nd Edition),’ 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 dialog, 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.

One of the main challenges in hydrogen production via electrolysis is the reliable measurement of the electrical work supplied. In this work, a robust electronic data acquisition system was developed to obtain precise and accurate data to evaluate the electrical work. The electrolytic concentration and electrical work were the main variables in this study. The supplied electrical energy was analyzed under both constant and pulsed voltage conditions. The results reveal that hydrogen production depends on voltage amplitude, PWM, and electrolyte concentration. The applied voltage shows a slight positive correlation with hydrogen production. PWM influences hydrogen production in the range of 0 to 1 Hz, while no significant effect is observed at higher frequencies. Electrolyte concentration has a stronger influence on hydrogen production in the range of 0.125 to 0.25 M. The optimal operating conditions were identified at 0.375 M, 1 Hz and 6 VDC, and under these conditions the hydrogen production is 0.145 mL/s and the specific energy is 165 kWh/kg. Full article

Molecular hydrogen, the basis of hydrogen energy, is formed in many physical and chemical processes, including the absorption of gamma-ray energy by liquid cyclohexane. From the point of view of energy consumption, the stages of gamma radiolytic formation of molecular hydrogen have not been quantified. By means of a new energy method, we analyzed the amounts of released molecular hydrogen during gamma irradiation of liquid cyclohexane in the absence and presence of small additives of bicyclic mono- and dienes RH (initial concentrations of C0(RH) ≈ 5 × 10−3 M/L), depending on the first ionization potentials of the components of solutions determined in the gas phase. Using the new energy method, four primary intermediates—radical anion, electronically excited molecule, radical cation, and superexcited molecule—of liquid cyclohexane gamma radiolysis were identified. Energy, mechanistic, and spin relationships and connections between these four cyclohexane intermediates were established. The experimental value of the adiabatic electron affinity of the cyclohexane molecule is −2.01 eV. The energy of formation of the superexcited cyclohexane molecule is 18 eV (gas phase). Using the energy method, it is shown that an increase in C0(RH) concentrations from 5 × 10−3 to 0.1 M/L leads to a change in the mechanism of RH consumption. Instead of RH activation, as a result of the single electron transfer reaction, RH polymerization begins, which is initiated by cyclohexyl radicals. Full article

This study introduces an integrated Life Cycle Assessment–Multi-Criteria Decision Analysis–Nash Equilibrium (LCA–MCDA–NE) framework to assess the feasibility of hydrogen energy storage (HES) in Philippine island grids. It starts with a cradle-to-gate LCA of hydrogen production across various electricity mix scenarios, from diesel-dominated Small Power Utilities Group (SPUG) systems to high-renewable configurations, quantifying greenhouse gas emissions. These impacts are normalized and integrated into an MCDA framework that considers four stakeholder perspectives: Regulatory (PRF), Developer (DF), Scientific (SF), and Local Social (LSF). Attribute utilities for Maintainability, Energy Efficiency, Geographic–Climatic Suitability, and Regulatory Compliance inform a 2 × 2 strategic game where net utility gain (Δ) and switching costs (C1, C2) influence adoption behavior. The findings indicate that the baseline Nash Equilibrium favors non-adoption due to limited utility gains and high switching barriers. However, enhancements in Maintainability and reduced costs can shift this equilibrium toward adoption. The LCA results show that meaningful decarbonization occurs only when low-carbon generation exceeds 60% of the electricity mix. This integrated framework highlights that successful HES deployment in remote grids relies on stakeholder coordination, reduced risks, and access to low-carbon electricity, offering a replicable model for emerging economies.
