Special Issue Information

Dear Colleagues,

Green hydrogen is considered the fuel of the future. The possibility of producing hydrogen utilizing several different renewable energy sources (e.g., solar and wind) will allow, on one hand, the efficient exploitation of this intermittent and unevenly distributed energy source and, on the other hand, the threatening issues associated with greenhouse gas emissions to be tackled. The transition from a fossil fuel-based society to a hydrogen-based society is among the biggest technological challenges that humankind will face in the next 50 years. To overcome this epochal challenge, significant technological advances must be made in the following three technological fields: hydrogen production, hydrogen storage, and hydrogen distribution.In this regard, this Special Issue aims to publish original high-quality research papers as well as review articles that address physically and/or through the use of simulation tools the production of green hydrogen, the storage of hydrogen, and the distribution of hydrogen. Potential topics of interest include, but are not limited to, the following: 1. Development of materials and systems for the production of green hydrogen (e.g., electrolysis, thermal, biochemical, photonic, electrothermal, photothermal, and photoelectric);2. Development of materials for hydrogen storage (e.g., metal hydride-based systems, molecular organic frameworks, and liquid organic carriers);3. Development of hydrogen storage tanks (e.g., for solid-state storage, compressed gas storage, and cryogenic liquid storage);4. Hydrogen distribution and infrastructures (e.g., hydrogen purification, hydrogen distribution through pipelines, and hydrogen compression).

On the Cycle Stability and Macroscopic Structure of Iron Oxide Pellets for Thermochemical Hydrogen Storage: Influence of Water Content during the Pelletizing Process

by Lea Huber, Melanie Heindl, Marc Schlosser, Arno Pfitzner and Belal Dawoud

Abstract

Hydrogen storage based on the repeated reduction and oxidation (redox) reactions of iron oxide/iron composites represents a promising technology. This work is dedicated to studying the influence of the amount of water added during the pelletizing process on the cycle stability and structure of iron oxide pellets. The storage composites were prepared from iron oxide (Fe₂O₃) and 10 wt.-% support material (cement) with different amounts of water (18 and 33 wt.-%) in a laboratory-scale pelletizing disk. To evaluate the cycle stability of the composites, the kinetics of the redox reactions were experimentally measured at 800

^{°}

C in an atmosphere of 50% N₂ and 50% H₂ (reduction) or 50% steam (oxidation), respectively. Moreover, the structure of the pellets was analyzed by micro-computed tomography scans. It turned out that pellets with higher water contents attained faster kinetics and a higher cycle stability. The sample with the least water content (18 wt.-%) needed about 26 min and 19 min to reach a conversion rate of 80% during the reduction and oxidation reactions of the sixth redox cycle, respectively. In contrast, the sample with the highest water content (33 wt.-%) could achieve the same conversion rate after 18 min (reduction) and 13 min (oxidation) during the ninth redox cycle. Full article

Abstract

In the climate change mitigation context based on the blue hydrogen concept, a narrative frame is presented in this paper to build the argument for solving the energy trilemma, which is the possibility of job loss and stranded asset accumulation with a sustainable energy solution in gas- and oil-rich regions, especially for the Persian Gulf region. To this aim, scientific evidence and multidimensional feasibility analysis have been employed for making the narrative around hydrogen clear in public and policy discourse so that choices towards acceleration of efforts can begin for paving the way for the future hydrogen economy and society. This can come from natural gas and petroleum-related skills, technologies, experience, and infrastructure. In this way, we present results using multidimensional feasibility analysis through STEEP and give examples of oil- and gas-producing countries to lead the transition action along the line of hydrogen-based economy in order to make quick moves towards cost effectiveness and sustainability through international cooperation. Lastly, this article presents a viewpoint for some regional geopolitical cooperation building but needs a more full-scale assessment. Full article
