Abstract
In the context of the global transition to renewable energy, free-flow hydro turbines (FFHTs) are of particular interest as an environmentally friendly alternative to traditional dam-based hydroelectric power plants. Their application is particularly relevant for China, which has significant, but geographically unevenly distributed hydroelectric potential. The objective of the study is to assess the potential for FFHT application in various regions of China based on a comprehensive consideration of hydrological and environmental factors. Using data from 58 hydro posts for the period 2010-2023, the hydrological stability index (Ig) and the environmental impact coefficient (Ke) were calculated. An integral suitability index (P) was developed, allowing for a quantitative assessment of the trade-off between energy efficiency and environmental risks. It was found that the most favorable regions for FFHT implementation are Zhejiang (P=0.67) and Guangdong (P=0.51), while in Yunnan and Sichuan the application of technologies requires additional restrictions and adaptation measures. Recommendations are provided for the selection of turbine types and capacity, taking into account regional specifics.
