Evaluation on potential of shallow geothermal energy resources and economic and environmental benefits in Xiongan new area
According to the occurrence conditions and distribution characteristics of shallow geothermal energy resources in Xiongdong area of Xiongan New Area,the potential of shallow geothermal energy resources in this area is estimated,and the exploitation and utilization is evaluated from the perspective of economic and environmental benefits.The results show that the total shallow geothermal capacity of 150m shallow rock and soil bodies in Xiongdong area is about 4.7×1012kJ/℃,the total static reserves of shallow geothermal energy are about 23.4×1012kJ,and the average resource potential of buried pipe heat transfer under summer cooling conditions is 433,000 m2/km2.The average resource potential of heating conditions in winter is 859,000 m2/km2.From the perspective of economic benefit,when the utilization rate of shallow geothermal energy development is 25%,about 6077 tons of standard coal can be saved in Xiongdong District throughout the year,about 2006 million yuan of annual cost can be saved,14,501 tons of carbon dioxide can be reduced,103 tons of sulfur dioxide can be reduced,and 49 tons of dust can be reduced.
