    Characteristics of geothermal resources and carbon emission reduction potential in Dafeng District, Jiangsu Province

    • This paper is the result of geothermal geothermal geological survey engineering. ObjectiveDafeng District, located in the northern part of Yancheng City, Jiangsu Province, is an area with abundant geothermal resources. It is of great practical significance to systematically study the characteristics of geothermal resources for the potential of coal and emissions reduction in the development and proper utilization of local geothermal resources. This is to strive for the strategic goal of achieving peak carbon dioxide emissions as soon as possible. MethodsBy comparing and analyzing the "heat source, channel, reservoir, and cap" of geothermal geological conditions for three typical geothermal wells in Hengbei Village, Holland Flower Sea Geothermal Well, and Milu Town Geothermal Well in Dafeng District, the characteristics of geothermal resources in Dafeng District were studied and summarized. ResultsThrough the evaluation of water quality and theoretical calculations of mineable and reserve amounts of geothermal wells in this area, we surmised that the geothermal well development and utilization in this area is mainly towards physical therapy,bathing,and heating. The theoretical total coal-saving amount that can be achieved through the exploitation of the geothermal resources in the three wells is 8, 884 tons per year, and the corresponding CO2 emissions reduction is 21, 197 tons per year. The theoretical total coal-saving amount that can be achieved through the storage of geothermal water in the resources reserved area of the three geothermal wells in Hengbei Village, Holland Flower Sea Geothermal Well, and Milu Town is 18, 885, 886 tons, corresponding to a CO2 emissions reduction of 45, 061, 725 tons. ConclusionsThe results of this study provide basic evidence or references for the exploration and development of geothermal resources and the analysis of carbon emissions reduction potential in the Dafeng District.
