Hot Spring Capital of China - Status of the Development and Utilization of Geothermal Resources in Tianjin

Abstract

Tianjin is a beautiful city, located at the east of the capital Beijing, near the Bohai Gulf. Tianjin bears rich mid- low temperature geothermal resources, the water temperature of the geothermal wells pump out up to 113°C. The history of mining of geothermal resources spans more than 80 years, and direct use of geothermal fluids in Tainjin ranks the first in the world. The Chinese government awarded the first "hot spring capital of China" to Tianjin, and the utilization of geothermal energy brings considerable economic benefits. In recent years, to solve the historical problems such as the pressure of geothermal reservoir declining too fast, low reinjection amount, and the extensive patterns of development and utilization, local administrative authorities adopted a series of measures and enacted laws and regulations, and strictly manage according to laws, to secure benign development of the geothermal resources.
