Abstract

Abstract: The use of geothermal energy and its associated technologies has been increasing worldwide. However, there has been little paradigmatic research conducted in this area. This paper proposes a systematic methodology to research the development trends for the sustainable development of geothermal energy. A novel data analysis system was created to research the geothermal energy utilization trends, and a technological paradigm theory was adopted to explain the technological changes. A diffusion velocity model was used to simulate and forecast the geothermal power generation development in the diffusion phase. Simulation results showed that the development of installed capacity for geothermal generation had a strong inertia force along with the S-curve. Power generation from geothermal power sources reached a peak in 2008 and is estimated to be saturated by 2030. Geothermal energy technologies in hybrid power systems based on other renewable energy sources look to be more promising in the future. Highlights: The novel concept of geothermal energy utilization technological paradigm is proposed. A data analysis system is created to visualize the keyword foci. The diffusion velocity model has a strong inertia force along with the S-curve. Geothermal power generation has reached a peak in 2008 and is estimated to be saturated by 2030. Geothermal energy technologies in hybrid power systems are identified as future utilization trajectories.
