Special Issue Information

Dear Colleagues,

The global hydrogen demand is found to continuously increase each year. Global hydrogen market is already valued at hundreds of billions of dollars per year. As it is known, hydrogen can be used safely for a wide range of applications, i.e., in food, metal, glass and chemical industries. In addition, according to energy crisis and environmental concern, hydrogen has been driven to become one of alternative energy carriers for power generation and is considered as a straightforward solution to issues related pollution and global warming. To meet the requirement of global demand, technologies to produce hydrogen are therefore essential and is considered as significance. To date, the development of hydrogen production technologies is in different stages, ranging from already commercial to the early stage laboratory development of new technologies for long-term benefits.

This special issue on “Hydrogen production technology” aims to gather outstanding researches and the comprehensive coverage of all aspects related to the hydrogen production technology, covering a wide range of technologies to produce hydrogen from a variety of resources and technologies in both economically and environmentally friendly ways. This special issue will bring together high-quality research articles on the different aspects of hydrogen production technology including current status and remaining challenges.  Topics include, but not are limited to:

  • Hydrogen production technologies, including chemical and biological processes
  • Theoretical and experimental investigation for hydrogen production process design
  • Integrated process development relating to the production of hydrogen and its utilization

The use of hydrogen gas as a means of decoupling supply from demand is crucial for the transition to carbon-neutral energy sources and a greener, more distributed energy landscape. This work shows how simple commercially available titanium nitride coatings can be used to extend the lifetime of 316 grade stainless-steel electrodes for use as the cathode in an alkaline electrolysis cell. The material was subjected to accelerated ageing, with the specific aim of assessing the coating’s suitability for use with intermittent renewable energy sources. Over 2000 cycles lasting 5.5 days, an electrolytic cell featuring the coating outperformed a control cell by 250 mV, and a reduction of overpotential at the cathode of 400 mV was observed. This work also confirms that the coating is solely suitable for cathodic use and presents an analysis of the surface changes that occur if it is used anodically. Full article

This study presents the Computational Fluid Dynamics (CFD) thermal design and experimental tests results for a multi-tubular solar reactor for hydrogen production based on the ferrite thermochemical cycle in a pilot plant in the Plataforma Solar de Almería (PSA). The methodology followed for the solar reactor design is described, as well as the experimental tests carried out during the testing campaign and characterization of the reactor. The CFD model developed for the thermal design of the solar reactor has been validated against the experimental measurements, with a temperature error ranging from 1% to around 10% depending on the location within the reactor. The thermal balance in the reactor (cavity and tubes) has been also solved by the CFD model, showing a 7.9% thermal efficiency of the reactor. CFD results also show the percentage of reacting media inside the tubes which achieve the required temperature for the endothermic reaction process, with 90% of the ferrite pellets inside the tubes above the required temperature of 900 °C. The multi-tubular solar reactor designed with aid of CFD modelling and simulations has been built and operated successfully. Full article

The available energy can be effectively upgraded by adopting smart energy conversion measures. The biodegradability of biomass can be improved by employing pretreatment techniques; however, such methods result in reduced energy efficiency. In this study, microwave (MW) irradiation is used for green algae (Enteromorpha) pretreatment in combination with iron oxide nanoparticles (NPs) which act as a heterogeneous catalyst during anaerobic digestion process for biogas enhancement. Batch-wise anaerobic digestion was carried out. The results showed that MW pretreatment and its combination with Fe3O4 NPs produced highest yields of biogas and hydrogen as compared to the individual ones and control. The biogas amount and hydrogen % v/v achieved by MW pretreatment + Fe3O4 NPs group were 328 mL and 51.5%, respectively. The energy analysis indicated that synergistic application of MW pretreatment with Fe3O4 NPs produced added energy while consuming less input energy than MW pretreatment alone. The kinetic parameters of the reaction were scientifically evaluated by using modified Gompertz and Logistic function model for each experimental case. MW pretreatment + Fe3O4 NPs group improved biogas production potential and maximum biogas production rate. Full article

Title: Process Design of Pump-free Ebullated-bed Residual Oil Hydrocracking with Gas Recovery System: Integration of Axial-dispersion Reactor Model and Commercial Process Simulator
Abstract: Ebullated-bed residual oil hydroprocessing is one of the most efficient method for vacuum residue (VR) conversion. SINOPEC has developed pump-free ebullated-bed reactor (PF-EBR), which utilized fluidized-induced internal circulation to promote self-fluidization of catalyst bed. Due to the complex mass transfer phenomenon, conventional process simulation software cannot model PF-EBR hydrocracking process in detail, and therefore limited process design and optimization. This study modeled PF-EBR with 5-lump axial-dispersion model, and integrated it with ASPEN HYSYS through COM object API; a 3 million tonne/year PF-EBR hydrocracking process with membrane-aided hydrogen recovery system was constructed and simulated in HYSYS based on the developed model; reaction kinetics and product distribution were validated by batch and industrial experimental results. This study provided efficient and model-based simulation tool for designing and optimizing PF-EBR hydrocracking process.

Abstract: Thermal interaction between a flame and heat conducting burner has significant effect on combustion characteristics of micro diffusion flame. The effect of wall thickness on combustion characteristics of non-premixed hydrogen micro-jet flames were studied by two-dimensional
numerical computation with detailed chemistry. The hydrogen jet diffusion flames achieved by micro fuel tubes with the same inner diameter and length but different wall thicknesses were computed. The
heat exchange between solid tube and gases were included in the numerical computation. The distributions of flame temperature, OH radicals, details of thermal interaction and combustion efficiency were
analyzed for comparison. It was found that the temperature distribution, flame shape and heat recirculation effect are varied with the fuel flow velocity, and they are affected by the wall thickness. The mechanism of wall thickness on the combustion characteristics of hydrogen jet diffusion flame was analyzed. Finally, an interesting numerical experiment was conducted to give a further explanation of the effect of heat recirculation and to provide guidance of thermal management of the micro burner.
