The geothermal energy market will reach 70 billion during the 12th Five-Year Plan period

With the increase of energy-saving and emission-reduction efforts, as an important clean energy, the application of geothermal energy has received more and more attention. The author was recently informed by the Ministry of Science and Technology that the Ministry of Science and Technology has compiled and completed the "Chinese geothermal energy utilization technology and application" brochure. According to the Ministry of Science and Technology, the ground-source heat pump industry will have a huge space in the future, with sales currently exceeding 8 billion yuan, and growing at a rate of more than 20% per year.

The Ministry of Science and Technology predicts that during the “12th Five-Year Plan” period, China will complete about 350 million square meters of ground-source heat pump heating (refrigeration). At that time, the total market for the development and utilization of geothermal energy will be at least 70 billion yuan.

In order to speed up the transformation and utilization of geothermal energy utilization technologies and promote the development and utilization of new energy, from April 2011 to March 2012, the Ministry of Science and Technology and the Chongqing Science and Technology Commission jointly organized and conducted research and research on geothermal energy utilization technologies and applications throughout the country. Completed the "Chinese geothermal energy utilization technology and application" brochure.

The Ministry of Science and Technology stated in the brochure that China has a vast territory and a large amount of shallow low-temperature energy is available. The “Twelfth Five-Year Plan” clearly states that non-fossil energy will account for more than 15% of the future energy structure. Therefore, it can be predicted that with the rapid progress of geothermal energy utilization technology, geothermal energy utilization will surely occupy a more important position in China's future energy utilization.

Ground source heat pump is a kind of low-grade heat source that uses shallow water sources (groundwater, seawater, river water, lake water, etc.) or underground soil heat sources on the surface of the earth. Through the heat pump and refrigeration cycle, the ground source heat pump can be used for summer air conditioning and heat production. Winter heating is used.

According to industry sources, ground source heat pump heating is more economical than conventional electric heating or fuel heating and gas heating. It usually produces the same amount of heat. The ground source heat pump consumes only 1/4 to 1 of the electric power consumption. 5. Therefore, the ground source heat pump market is vast.

The Ministry of Science and Technology predicts that during the “Twelfth Five-Year Plan” period, China is expected to complete ground-source heat pump heating (cooling) area of ​​about 350 million square meters. By then, the total market for the development and utilization of geothermal energy will be at least 70 billion yuan.
