Geothermal energy, a clean energy source that has yet to be fully exploited, holds enormous potential. However, in the context of geothermal power generation, constraints such as relatively low temperatures lead to lower power generation efficiency. The distributed energy system aligns well with geothermal energy in terms of geography and application form. Natural gas plays an auxiliary role in providing thermal energy within this system. By leveraging the gradient utilization of these two energy sources, it is possible to effectively enhance power generation efficiency and significantly reduce costs.
