Evaluation and application suggestion of shallow geothermal energy resources at coast industrial area in Taizhou city

Based on Quaternary geological and hydrogeological conditions, the occurrence characteristics of shallow geothermal energy of coast industrial area in Taizhou are analyzed from shallow geothermal field and thermophysical properties of rocks.The suitability of development and utilization of ground source heat pump system in coast industrial area is evaluated.The total geothermal capacity is 2.99×10¹³ kJ/℃, which converted into equivalent coal is 1.02×10⁹ kg, and the available shallow geothermal energy resources are 9.21×10¹² kJ, which converted into equivalent coal is 5.26×10⁸ kg.In addition, the development potential of shallow geothermal energy by ground source heat pump system in coast industrial area is evaluated, and the results show that the available cooling area in summer is 4.2×10⁶ m², while which is 6.7×10⁶ m² in winter.Combined with the development plan of circular economy industrial agglomeration area in Taizhou bay, the development and application suggestions of shallow geothermal energy are put forward.
