Special Issue Information

Dear Colleagues,

The drive to develop sustainable and clean energy sources has placed hydrogen at the forefront as a versatile and environmentally friendly fuel. Hydrogen production technologies are critical in the transition towards a green energy economy, offering significant potential to reduce carbon emissions and enhance energy security. This call for papers aims to gather the latest scientific advances and technological innovations in the field of hydrogen production, focusing on new materials and methods that can improve efficiency, cost-effectiveness, and sustainability.

We invite original research articles, review papers, and mini-reviews on recent advances in hydrogen production. Topics of interest include, but are not limited to, the following:

Hydrogen production technologies:

  • Electrolysis (PEM, alkaline, solid oxide);
  • Thermochemical water splitting;
  • Photocatalytic and photoelectrochemical water splitting;
  • Biological hydrogen production (microbial electrolysis, fermentation);
  • Plasma-assisted hydrogen production.

High-temperature approaches and chemical processes:

  • Thermochemical cycles (sulphur–iodine, calcium–bromine, copper–chlorine, etc.);
  • High-temperature steam electrolysis;
  • Gasification of biomass and fossil fuels;
  • Reforming processes (steam methane reforming, autothermal reforming, partial oxidation);
  • High-temperature co-electrolysis of CO2 and H2O.

Advanced materials for hydrogen production:

  • Catalysts for water splitting (electrocatalysts, photocatalysts, thermocatalysts);
  • Novel electrode materials;
  • Membranes for electrolysis and separation;
  • Nanomaterials and nanostructured materials (organocatalysts).

Hydrogen production from renewable sources:

  • Solar-driven hydrogen production;
  • Wind energy integration with hydrogen production systems;
  • Biomass and bio-waste conversion to hydrogen;
  • Integration of renewable energy sources with hydrogen production technologies.

This study proposes a novel system integrating a molten carbonate fuel cell (MCFC) with a dry reforming process (DR-MCFC) and develops a corresponding simulation model. In a DR-MCFC, the reacting gases from the dry reforming of methane (DRM) process are fed into a molten carbonate fuel cell. CH4 and CO2 were used as the reaction gases, while N2 was employed as the carrier gas and introduced into the DRM. Following the DRM, the reformed gases were humidified and injected into the anode of the MCFC. A simulation model combining the dry reforming process and the MCFC was developed using COMSOL Multiphysics to evaluate the system’s performance and feasibility. The mole fraction of H2 after the DRM ranged from 0.181 to 0.214 under five different gas conditions. The average current density of the fuel cell varied between 1321.5 and 1444.9 A·m−2 at a cell voltage of 0.8 V, which was up to 27.07% lower than that of a conventional MCFC operating at 923 K due to the lower hydrogen concentration in the anode. Based on these results, the integration of dry reforming with the MCFC’s operation did not cause any operational issues, demonstrating the feasibility of the proposed DR-MCFC system. Full article

The primary methods for hydrogen transportation include gaseous storage and transport, liquid hydrogen storage, and transport via organic liquid carriers. Among these, pipeline transportation offers the lowest cost and the greatest potential for large-scale, long-distance transport. Although the construction and operation costs of dedicated hydrogen pipelines are relatively high, blending hydrogen into existing natural gas networks presents a viable alternative. This approach allows hydrogen to be transported to the end-users, where it can be either separated for use or directly combusted, thereby reducing hydrogen transport costs. This study, based on the GERG-2008 equation of state, conducts experimental tests on the compressibility factor of hydrogen-doped natural gas mixtures across a temperature range of −10 °C to 110 °C and a pressure range of 2 to 12 MPa, with hydrogen blending ratios of 5%, 10%, 20%, 30%, and 40%. The results indicate that the hydrogen blending ratio, temperature, and pressure significantly affect the compressibility factor, particularly under low-temperature and high-pressure conditions, where an increase in the hydrogen blending ratio leads to a notable rise in the compressibility factor. These findings have substantial implications for the practical design of hydrogen-enriched natural gas pipelines, as changes in the compressibility factor directly impact pipeline operational parameters, compressor characteristics, and other system performance aspects. Specifically, the introduction of hydrogen alters the compressibility factor of the transported medium, thereby affecting the pipeline’s flowability and compressibility, which are crucial for optimizing and applying the performance of hydrogen-enriched natural gas in transportation channels. The research outcomes provide valuable insights for understanding combustion reactions, adjusting pipeline operational parameters, and compressor performance characteristics, facilitating more precise decision-making in the design and operation of hydrogen-enriched natural gas pipelines.
