“…As a result, policy-making outcomes in the US, Europe and China will have a profound impact on green hydrogen production and storage over the next five years. If these policies are implemented, these countries will be responsible for two-thirds of this growth, and Asia will account for the most significant part and become the second largest producer in the world, with the collaboration of China and also India (Raman et al, 2022). It can be understood that Asia and Europe lead research on green hydrogen in the world (Vallejos-Romero et al, 2023).…”

“…In response to the global challenge of climate change, 136 countries, accounting for 90 percent of global GDP and 85 percent of the population, have already set zero-carbon emission targets, requiring decarbonization of all sectors of the economy. Thus, it is noted that green hydrogen produced from renewable energy sources (Thapa, Neupane, Yang & Lee, 2021), poses little or no threat to the environment and increasing its production will support decarbonization targets (Raman, Nair, Prakash, Patwardhan & Nedungadi, 2022). In other words, a green hydrogen production system consisting of water electrolysis and a renewable energy plant must be expanded to prepare for the future hydrogen society (Lee, Choe, Lee, Gu, Cho, Won & Lim, 2022).…”

“…It can thus be understood that green hydrogen is an emerging area of study (Raman et al, 2022), as a result of being observed as a global trend of research around hydrogen as an essential component for achieving clean energy (Camargo et al, 2023). However, no studies have been found that investigate research trends and the potential of green hydrogen, bringing by way of a new perspective and analysis as is the case of Social Network Analysis (ARS), although a literature review reveals that previous authors had conducted bibliometric studies on green hydrogen (Zheng, 2021;Gevaert & Pause, 2022;Raman et al, 2022;Vallejos-Romero et al, 2023). It complements itself by stating that the theme of green hydrogen is still embryonic as far as studies on the subject of hydrogen and clean energy in global terms are concerned (Camargo et al, 2023).…”

Purpose: to investigate the behavior and tendency of the formation of social networks of the scientific production on the Green Hydrogen theme published in scientific journals indexed in EBSCO. Theoretical framework: the theme of green hydrogen has been gaining attention and strength in the current context of global energy transition, as it is a clean alternative for generating energy for electricity, industry, heating, and transport sectors, and, in replacing fuels to carbon base, influencing sustainable development. Method: bibliometric analysis techniques were used, and predominantly social network analysis (SAR) through one-mode and two-mode network analysis. Results and conclusion: evolution of the theme in academia; weak ties in co-authorship and institutional networks; relevance of China and its originating institutions in the scientific production of the subject investigated; the most central keywords were: hydrogen, green hydrogen, renewable energy, production and hydrogen production; and the most fruitful themes were: production, sustainability, energy and carbon emissions. It concludes with a macro and contemporary view of the theme of green hydrogen in the international literary academic field. Research implications: the present study contributed to a better understanding and understanding of the formation of collaboration networks of the actors involved in the process of building international scientific knowledge, and, by verifying that green hydrogen presents opportunities for economic growth and job creation, this research also contributes to creating an entrepreneurial and social research agenda. Originality/value: to investigate the international scientific production on the theme of green hydrogen, as this is an emerging theme in the global academic literature, and, therefore, to verify that the referred theme gains strength through researchers and their respective studies.

“…Bibliometric analysis is a method that is well-established and is employed to assess specific publications in the area of scientific research, as well as trend analysis [44][45][46]. Earlier researchers have conducted bibliometric analysis in various areas such as green economy [47,48], renewable energy [49], alternative fuels in shipping [50], hydrogen energy [51], energy and blockchain [52], green-hydrogen research [53], hydrogen economies [54], and sustainable development [55].…”

Research Progress, Trends, and Current State of Development on PEMFC-New Insights from a Bibliometric Analysis and Characteristics of Two Decades of Research Output

The consumption of hydrogen could increase by sixfold in 2050 compared to 2020 levels, reaching about 530 Mt. Against this backdrop, the proton exchange membrane fuel cell (PEMFC) has been a major research area in the field of energy engineering. Several reviews have been provided in the existing corpus of literature on PEMFC, but questions related to their evolutionary nuances and research hotspots remain largely unanswered. To fill this gap, the current review uses bibliometric analysis to analyze PEMFC articles indexed in the Scopus database that were published between 2000–2021. It has been revealed that the research field is growing at an annual average growth rate of 19.35%, with publications from 2016 to 2012 alone making up 46% of the total articles available since 2000. As the two most energy-consuming economies in the world, the contributions made towards the progress of PEMFC research have largely been from China and the US. From the research trend found in this investigation, it is clear that the focus of the researchers in the field has largely been to improve the performance and efficiency of PEMFC and its components, which is evident from dominating keywords or phrases such as ‘oxygen reduction reaction’, ‘electrocatalysis’, ‘proton exchange membrane’, ‘gas diffusion layer’, ‘water management’, ‘polybenzimidazole’, ‘durability’, and ‘bipolar plate’. We anticipate that the provision of the research themes that have emerged in the PEMFC field in the last two decades from the scientific mapping technique will guide existing and prospective researchers in the field going forward.

“…ISM can also be used to identify the key drivers and barriers to achieving SDG 3 Target 3.8 (Universal health coverage), such as the availability of healthcare resources, the quality of healthcare infrastructure, and the level of political commitment to health. Recent bibliometric studies have analyzed research topics like green hydrogen, women entrepreneurship, virtual learning environments, and their SDG mappings (Raman et al, 2022a;Raman et al, 2022b;Achuthan et al, 2022).…”

Interpretive Structural Modelling (ISM) is widely used to understand the complex connections between different components. This study presents a bibliometric overview of ISM research with a focus on its linkages to the Sustainable Development Goals (SDG) and the impact of COVID-19. The study analyzed 1988 publications on ISM published between 2012 and 2021, of which 1202 were directly mapped to the SDG and 59 were related to COVID-19. The study identified key authors, institutions, countries, and journals involved in the research and their linkages to the SDG. The results showed that ISM research is strongly linked to SDG 12 (Responsible Consumption and Production) and SDG 9 (Industry, Innovation and Infrastructure). We also identified influential SDG based on centrality measures like betweenness and eigenvector. The top four countries contributing to ISM publications were India, China, the United Kingdom, and the United States. The most frequently cited journals were Benchmarking: An International Journal, Sustainability, Journal of Modelling in Management, and Journal of Cleaner Production. Four main clusters were identified in the ISM research, including (1) integration with AHP & Fuzzy Logic for promoting sustainability alignment, (2) ISM-based strategy development for various stakeholders, (3) ISM-based decision-making in various fields, and (4) ISM-based risk evaluation. For the first time studies that used ISM approach to understand the epidemiological characteristics of COVID-19 were identified and their key findings were discussed. The study also identified several emerging topics for future ISM research, such as blockchain & IoT, environmental management systems, climate change adaptation, smart cities, and humanitarian logistics and their potential linkages to SDG.
