Research development and hotspots of geothermal energy based on bibliometrics
To promote the development and utilization of geothermal energy is an important choice to effectively advance the low-carbon energy structure and achieve the goal of"dual carbon".It is of great significance to accurately identify the development trend and research hotspots in the field of geothermal energy.Based on the bibliometric and content analysis,the paper systematically analyzes the development trend of geothermal energy from the publication trend,the publications and influences from the aspects of countries and institutions,and the research hotspots.The findings indicate that the research papers show a rapid growth trend.The research is mainly concentrated in developed countries.The Chinese Academy of Science is the institution with the largest number of publications.The study of geothermal energy is an interdisciplinary research involving multiple disciplines.The research hotspots focus on the origin and distribution of geothermal energy,geothermal resource exploitation and reservoir enhancement,geothermal heating and cooling,geothermal power generation and geothermal water.
