Control factors and guidelines for urban-scale shallow geothermal energy development based on control units: An example from Xiong’an

Abstract

Abstract:

The rational utilization of shallow geothermal energy (SGE) has great potential in promoting urban energy conservation, greenhouse emission reduction and green development. In addition to the effects of geological conditions, urban-scale SGE utilization and development is also affected by urban planning. Based on the regulatory planning of the starting area of Xiong’an, this paper summarizes the main controlling factors—geological, resource and socio-ecological factors—and formulates a workflow of spatial suitability evaluation and guidance rules. First, fully considering the constrains from the main controlling factors, combined with the indoor and field test data from geothermal measurement, thermophysical property test, field thermal response test, etc., the single element analysis of 30 control units planned in the starting area was carried out. Then, the comprehensive evaluation of SGE development was performed, and the development guidelines were formulated. Factors including geothermal field conditions, hydrogeological conditions, heat conductivity, heat capacity, heating/cooling areas, urban planning and land subsidence directly affect the SGE utilization in Xiong’an. Within the study area, 43% of the control units demonstrated good suitability for SGE development. Such areas were designated as “utilizable area”, which were mainly distributed in the north in units A, B, C, and D, mainly in the developed urban areas with high comprehensive thermal conductivity, large heating/cooling load per unit area, and higher likelihood of SGE occurrences. Units with medium suitability, i.e., 33% of the control units, were designated as “limited utilization area”; they mainly included sporadic areas of unit E and other units, with medium comprehensive thermal conductivity, small heating/cooling load per unit area, and heat capacity. The rest 23%, designated as “restricted utilization area”, were poor suitability units, mainly included areas in the south in F unit, with rich water systems and restricted spatial planning. The research results provide support for the SGE utilization and development in the starting area of Xiong’an, and also provide a reference for standardized urban-scale SGE valuation.
