6 FAQs about [Hot Rock Energy Storage in China]

Why is hot dry rock important in China?

China has entered a period of rapid development of geothermal energy since 2010. As shallow geothermal energy promoting, the depth of hydrothermal geothermal exploration is increasing. The quality of Hot Dry Rock (HDR) and related exploratory technologies are better developed and utilized.

How much energy does hot dry rock use in China?

According to international hot dry rock standards, if we calculate the exploitable quantity as 2%, the potential energy from hot dry rock resources in China is about 4000 times the national energy consumption in 2018 (Wan et al., 2014).

Is hot dry rock a potential geothermal resource in China?

Utilizing information from plate tectonics characteristics, volcanic activities, and geothermal anomaly, this paper identifies areas where hot dry rock (HDR) may exist as potential geothermal resource in China.

Does China's exploration technology affect the development of hot and dry rock?

P1 I believe that the exploration technology of hot and dry rock resources in China is an important factor affecting the large-scale development of hot and dry rock. P2 I think China's hot dry rock high temperature drilling technology is an important factor affecting the large-scale development of hot dry rock.

How much heat does a dry hot rock store?

It is estimated that the total heat of dry hot rocks buried underground is 30 times more than the total amount of fossil energy, and the total heat storage can reach 2.52 × 10 25 J in China . Dry hot rock exploitation can be divided into the following processes: First, a “water injection well” is drilled into the dry hot rock from the surface.

How can dry hot rock be used as a geothermal resource?

High-temperature steam can be used for heating and electricity generation. Finally, the remaining warm water will be returned to the dry hot rock through injection wells, thus enabling energy recycling. Dry hot rock, a renewable geothermal resource, contains a lot of energy.
