Suitability assessment and zoning for the construction of compressed air energy storage plants in China
With the transformation of China's energy structure and the advancement of its dual carbon goals
compressed air energy storage (CAES) technology has garnered increasing attention and recognition within the global energy storage sector. This study aims to address existing research gaps in the evaluation methodology for the construction suitability of CAES power plants. First
we systematically collated quantitative evaluation indicators and corresponding calculation methods across five core dimensions
namely
energy security
power grid support
energy transition
economic benefits
and regional policy. Based on publicly released electricity consumption data
prevailing standards and specifications
and operational data of completed CAES projects across various regions in China
we performed quantitative analysis and statistical processing for each indicator. Subsequently
based on expert surveys
we established a weighting system for the aforementioned indicators using an analytic hierarchy process
developed a comprehensive construction suitability evaluation methodology
and completed a zonal calculation of the construction suitability of CAES power plants for each province in China. The results demonstrate that high-suitability zones for large-scale CAES power plants in China are mainly distributed in the eastern region (including Shandong
Jiangsu
and Guangdong provinces)
which are characterized by strong policy support
robust electricity demand
and favorable economic viability for project construction. Meanwhile
the northeastern region is classified as a low-suitability zone
attributable to limited policy support and relatively low electricity load. Comprehensive statistical results indicate that regions with relatively high-suitability account for approximately 35.5% of China's total territorial area
highlighting the broad development prospects of CAES technology in the country.
