Research on comprehensive utilization and key technologies of island geothermal in Hebei Province under background of"Dual Carbon"
Carbon peaking and neutrality are efforts to address China's prominent resource and environmental constraints.They are an in-evitable choice to promote ecological civilization construction,ensure energy security and efficiency,drive economic transformation and upgrading,and lead the response to climate change.As a geomorphic unit with both land and sea features,island has special ecological and environmental conditions and great pressure on resources and environment.Taking the island geothermal resources of Hebei Prov-ince as the research object,the calculation method of the deep and shallow geothermal resources of the island was explored,a compre-hensive analysis and evaluation of the water quality was made,and the suitable zoning of the development and utilization of shallow geo-thermal energy was carried out,and the occurrence conditions of the island geothermal resources in the province was preliminarily grasped.According to"one island and one policy",the comprehensive utilization model of island geothermal on Xiangyun Island and Dragon Island was put forward.The key technologies supporting the protection and utilization of island geothermal energy were explored,such as remote automatic monitoring,shallow geothermal energy utilization,geothermal tail water pressure salt,heat extraction without water(same layer recharge,well heat transfer)and"geothermal+"integrated utilization of multiple clean energy technologies.The re-search has a strong practical significance for the scientific and efficient utilization of geothermal energy in key islands of Hebei Prov-ince,and has positive reference significance for the ecological development and utilization of similar sandy islands,and will certainly contribute to the early realization of the"Dual Carbon"goal in coastal areas.
