Geothermal Resources in China

Abstract

Geothermal resource is widespread in China. The region with the richest resource is in the south-west of China which makes up about 51% of total found resource. Huabei makes up 17.27%, south center makes up 15.89%. The northeast and northwest regions of China are the poorest regions of geothermal resource which makes up about 3%. The growth rate of geothermal utilization in China has been 12% per year during the last decade. The total district heating in China serves 10 million m2. The heating market in the cities of Northern China is enormous and the geothermal resources widespread. Most of the geothermal reservoirs in China are in sedimentary formation, however, many of them have very limited recharge. Because of this, some geothermal fields have been doing reinjection into the reservoirs.
