Abstract

Research on biomass energy has witnessed substantial growth, fueled by the rising global emphasis on sustainable and renewable energy solutions. In this context, scientometric studies serve as a valuable tool, offering critical insights into research trends, knowledge gaps, and potential future directions for advancing biomass energy technologies. The study examines the scientometric trends and impact of biomass energy research between 1998 and 2022, focusing on key indicators such as citation rates, growth rates, publication efficiency, and authorship patterns. The analysis was conducted on 5,186 publications from India and 72,641 publications globally in the biomass energy sector during the period 1998–2022. Scientometric indicators, including average citations per paper, annual growth rate (AGR), exponential growth rate, activity index, publication efficiency index (PEI), relative growth rate (RGR), and doubling time (Dt), were used. In 2006, India achieved the highest average citations per paper (182.34), while globally, the highest average citations per paper (93.11) were recorded in 2002. The highest AGR of 80.00 was recorded in 2004, which also marked the peak exponential growth rate of 1.80, with 36 publications. In 2022, the highest activity index was recorded at 141.56. The maximum PEI value (4.85) was observed in 2006, with 32 publications. The study identified the top 25 contributing authors and journals in the field of biomass energy research. Additionally, it discussed the mean RGR and Dt for publications and citations, along with other key scientometric indicators. The findings demonstrate strong growth and a high citation impact in biomass energy research, with India and the global research community making significant contributions. Collaborative networks, particularly with developed countries, play a substantial role in advancing this field. These insights underscore the importance of continued research and collaboration in biomass energy to address global energy challenges.
