A systemic review of hydrogen supply chain in energy transition

《能源前沿（英文）》 2023年第17卷第1期页码 102-122 doi: 10.1007/s11708-023-0861-0

摘要： Targeting the net-zero emission (NZE) by 2050, the hydrogen industry is drastically developing in recent years. However, the technologies of hydrogen upstream production, midstream transportation and storage, and downstream utilization are facing obstacles. In this paper, the development of hydrogen industry from the production, transportation and storage, and sustainable economic development perspectives were reviewed. The current challenges and future outlooks were summarized consequently. In the upstream, blue hydrogen is dominating the current hydrogen supply, and an implementation of carbon capture and sequestration (CCS) can raise its cost by 30%. To achieve an economic feasibility, green hydrogen needs to reduce its cost by 75% to approximately 2 /kg at the large scale. The research progress in the midterm sector is still in a preliminary stage, where experimental and theoretical investigations need to be conducted in addressing the impact of embrittlement, contamination, and flammability so that they could provide a solid support for material selection and large-scale feasibility studies. In the downstream utilization, blue hydrogen will be used in producing value-added chemicals in the short-term. Over the long-term, green hydrogen will dominate the market owing to its high energy intensity and zero carbon intensity which provides a promising option for energy storage. Technologies in the hydrogen industry require a comprehensive understanding of their economic and environmental benefits over the whole life cycle in supporting operators and policymakers.

Recent advances of small-molecule fluorescent probes for detecting biological hydrogen sulfide

《化学科学与工程前沿（英文）》 2022年第16卷第1期页码 34-63 doi: 10.1007/s11705-021-2050-1

摘要： H₂S is well-known as a colorless, acidic gas, with a notoriously rotten-egg smell. It was recently revealed that H₂S is also an endogenous signaling molecule that has important biological functions, however, most of its physiology and pathology remains elusive. Therefore, the enthusiasm for H₂S research remains. Fluorescence imaging technology is an important tool for H₂S biology research. The development of fluorescence imaging technology has realized the study of H₂S in subcellular organelles, facilitated by the development of fluorescent probes. The probes reviewed in this paper were categorized according to their chemical mechanism of sensing and were divided into three groups: H₂S reducibility-based probes, H₂S nucleophilicity-based probes, and metal sulfide precipitation-based probes. The structure of the probes, their sensing mechanism, and imaging results have been discussed in detail. Moreover, we also introduced some probes for hydrogen polysulfides.

Production of hydrogen from fossil fuel: A review

《能源前沿（英文）》 2023年第17卷第5期页码 585-610 doi: 10.1007/s11708-023-0886-4

摘要： Production of hydrogen, one of the most promising alternative clean fuels, through catalytic conversion from fossil fuel is the most technically and economically feasible technology. Catalytic conversion of natural gas into hydrogen and carbon is thermodynamically favorable under atmospheric conditions. However, using noble metals as a catalyst is costly for hydrogen production, thus mandating non-noble metal-based catalysts such as Ni, Co, and Cu-based alloys. This paper reviews the various hydrogen production methods from fossil fuels through pyrolysis, partial oxidation, autothermal, and steam reforming, emphasizing the catalytic production of hydrogen via steam reforming of methane. The multicomponent catalysts composed of several non-noble materials have been summarized. Of the Ni, Co, and Cu-based catalysts investigated in the literature, Ni/Al₂O₃ catalyst is the most economical and performs best because it suppresses the coke formation on the catalyst. To avoid carbon emission, this method of hydrogen production from methane should be integrated with carbon capture, utilization, and storage (CCUS). Carbon capture can be accomplished by absorption, adsorption, and membrane separation processes. The remaining challenges, prospects, and future research and development directions are described.

Bilayer borophene: an efficient catalyst for hydrogen evolution reaction

《化学科学与工程前沿（英文）》 2024年第18卷第3期 doi: 10.1007/s11705-024-2389-1

摘要： The electrocatalytic hydrogen evolution reaction is a crucial technique for green hydrogen production. However, finding affordable, stable, and efficient catalyst materials to replace noble metal catalysts remains a significant challenge. Recent experimental breakthroughs in the synthesis of two-dimensional bilayer borophene provide a theoretical framework for exploring their physical and chemical properties. In this study, we systematically considered nine types of bilayer borophenes as potential electrocatalysts for the hydrogen evolution reaction. Our first-principles calculations revealed that bilayer borophenes exhibit high stability and excellent conductivity, possessing a relatively large specific surface area with abundant active sites. Both surface boron atoms and the bridge sites between two boron atoms can serve as active sites, displaying high activity for the hydrogen evolution reaction. Notably, the Gibbs free energy change associated with adsorption for these bilayer borophenes can reach as low as ‒0.002 eV, and the Tafel reaction energy barriers are lower (0.70 eV) than those on Pt. Moreover, the hydrogen evolution reaction activity of these two-dimensional bilayer borophenes can be described by engineering their work function. Additionally, we considered the effect of pH on hydrogen evolution reaction activity, with significant activity observed in an acidic environment. These theoretical results reveal the excellent catalytic performance of two-dimensional bilayer borophenes and provide crucial guidance for the experimental exploration of multilayer boron for various energy applications.

《工程（英文）》 doi: 10.1016/j.eng.2024.03.011

摘要： Hydrogen has emerged as a promising alternative to meet the growing demand for sustainable and renewable energy sources. Underground hydrogen storage (UHS) in depleted gas reservoirs holds significant potential for large-scale energy storage and the seamless integration of intermittent renewable energy sources, due to its capacity to address challenges associated with the intermittent nature of renewable energy sources, ensuring a steady and reliable energy supply. Leveraging the existing infrastructure and well-characterized geological formations, depleted gas reservoirs offer an attractive option for large-scale hydrogen storage implementation. However, significant knowledge gaps regarding storage performance hinder the commercialization of UHS operation. Hydrogen deliverability, hydrogen trapping, and the equation of state are key areas with limited understanding. This literature review critically analyzes and synthesizes existing research on hydrogen storage performance during underground storage in depleted gas reservoirs; it then provides a high-level risk assessment and an overview of the techno-economics of UHS. The significance of this review lies in its consolidation of current knowledge, highlighting unresolved issues and proposing areas for future research. Addressing these gaps will advance hydrogen-based energy systems and support the transition to a sustainable energy landscape. Facilitating efficient and safe deployment of UHS in depleted gas reservoirs will assist in unlocking hydrogen’s full potential as a clean and renewable energy carrier. In addition, this review aids policymakers and the scientific community in making informed decisions regarding hydrogen storage technologies.

《化学科学与工程前沿（英文）》 2021年第15卷第3期页码 464-482 doi: 10.1007/s11705-020-1983-0

摘要： The global energy market is in a transition towards low carbon fuel systems to ensure the sustainable development of our society and economy. This can be achieved by converting the surplus renewable energy into hydrogen gas. The injection of hydrogen (≤10% v/v) in the existing natural gas pipelines is demonstrated to have negligible effects on the pipelines and is a promising solution for hydrogen transportation and storage if the end-user purification technologies for hydrogen recovery from hydrogen enriched natural gas (HENG) are in place. In this review, promising membrane technologies for hydrogen separation is revisited and presented. Dense metallic membranes are highlighted with the ability of producing 99.9999999% (v/v) purity hydrogen product. However, high operating temperature (≥300 °C) incurs high energy penalty, thus, limits its application to hydrogen purification in the power to hydrogen roadmap. Polymeric membranes are a promising candidate for hydrogen separation with its commercial readiness. However, further investigation in the enhancement of H /CH selectivity is crucial to improve the separation performance. The potential impacts of impurities in HENG on membrane performance are also discussed. The research and development outlook are presented, highlighting the essence of upscaling the membrane separation processes and the integration of membrane technology with pressure swing adsorption technology.

A mini-review of ferrites-based photocatalyst on application of hydrogen production

《能源前沿（英文）》 2021年第15卷第3期页码 621-630 doi: 10.1007/s11708-021-0761-0

摘要： Photocatalytic water splitting for hydrogen production is a promising strategy to produce renewable energy and decrease production cost. Spinel-ferrites are potential photocatalysts in photocatalytic reaction system due to their room temperature magnetization, the high thermal and chemical stability, narrow bandgap with broader visible light absorption, and proper conduction band energy level with strong oxidation activity for water or organic compounds. However, the fast recombination of the photoexcited electrons and holes is a critical drawback of ferrites. Therefore, the features of crystallinity, particle size, specific surface area, morphology, and band energy structure have been summarized and investigated to solve this issue. Moreover, composites construction with ferrites and the popular support of TiO₂ or g-C₃N₄ are also summarized to illustrate the advanced improvement in photocatalytic hydrogen production. It has been shown that ferrites could induce the formation of metal ions impurity energy levels in TiO₂, and the strong oxidation activity of ferrites could accelerate the oxidation reaction kinetics in both TiO₂/ferrites and g-C₃N₄/ferrites systems. Furthermore, two representative reports of CaFe₂O₄/MgFe₂O₄ composite and ZnFe₂O₄/CdS composite are used to show the efficient heterojunction in a ferrite/ferrite composite and the ability of resistance to photo-corrosion, respectively.

Ductility loss of hydrogen-charged and releasing 304L steel

Yanfei WANG, Jianming GONG, Yong JIANG, Wenchun JIANG, Wang JIANG

《机械工程前沿（英文）》 2013年第8卷第3期页码 298-304 doi: 10.1007/s11465-013-0265-7

摘要：

The mechanical properties and fracture behavior of 304L austenitic stainless steel after cathodic hydrogen charging and hydrogen spontaneously releasing are investigated by tensile tests. Flat tensile specimens were cathodic hydrogen charged at various current densities. For each density, two specimens were charged at the same condition. When the charging process completed, one specimen was tensile immediately to fracture and the other was aged to release the hydrogen out of it and then was also tensile to fracture. The resulting tensile properties and micrographs of fracture surfaces of these specimens were evaluated and compared. The results show ductility loss occurred in the hydrogen-charged specimens and the loss increased as the current density increasing. After hydrogen releasing, the specimens recovered a certain extent but not all of its original ductility. Scanning electron microscope (SEM) micrographs of fracture surfaces reveal that irreversible damage had developed in the hydrogen-releasing specimens during the releasing process rather than the charging process. This consequence can be ascribed to the high tensile stress caused by non-uniform hydrogen distribution during hydrogen releasing.
