Special Issue Information

Dear Colleagues,

Global warming has shifted the world's energy focus to green and clean energy. Hydrogen energy, with its zero pollution, high energy density, abundant resources, and wide range of uses, is considered to be the key part of energy industry transformation and plays an important role in the world's energy system. Hydrogen production technology is the foundation for the development of the hydrogen energy industry, and it is an important link in realizing hydrogen energy applications. This Special Issue considers all aspects of experimental techniques, numerical simulations, applications, and basic research related to green and clean hydrogen to replace fossil fuels and reduce greenhouse gas emissions, thus contributing to sustainable development. More hydrogen production programs are underway or planned to promote green hydrogen energy. Green hydrogen produced from renewable energy sources such as solar and wind power not only eliminates carbon emissions but also reduces the cost of hydrogen production. In addition, we are considering related research on hydrogen utilization to improve resource utilization.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Research on green hydrogen energy production technology;
  • Research related to hydrogen production technology from biomass;
  • waste-to-energy conversion;
  • Research related to hydrogen production technology from electrolyzed water;
  • Research on hydrogen production from the improved reforming of fossil fuels;
  • Hydrogen production from industrial by-product gases;
  • Research on hydrogen production from renewable energy sources;
  • Research on safe storage and transportation technology for hydrogen energy;
  • Research on hydrogen refueling technology;
  • Hydrogen fuel cell technology and its application;
  • Hydrogen fuel engine;
  • Hydrogen power dissemination.

Hydrogen is an important component of renewable energy and is essential for sustainable development. The cryogenic energy storage system can solve the problem of hydrogen storage. A packed bed can be applied in a cryogenic energy storage system. It is crucial to understand the cryogenic energy discharging in a packed bed. In the present work, the CFD-DEM coupling method is used to investigate the pore-scale flow and heat transfer characteristics of cryogenic hydrogen flowing through the packed bed. To demonstrate the characteristics of the pore-scale heat transfer of the hydrogen flow in a packed bed, the local radial-averaged and axial-averaged temperatures and velocities are analyzed in detail, depending on the local porosity distribution. The pore-scale radial-averaged velocity distribution is proportional to the local radial porosity distribution, whereas the pore-scale radial-averaged temperature characteristics are inverse. Moreover, for the heat exchange of the cryogenic hydrogen flow in a packed bed, it can be found that the cryogenic hydrogen flow is fully heated at an axial distance of approximately 7 dp. Finally, considering that the thermo-physical properties of cryogenic hydrogen are sensitive to the temperature in a packed bed, the friction factor and Nusselt number in the packed bed are also analyzed under various operating parameters, which are in good agreement with certain classic empirical correlations.
