Abstract:

The deep aquifer thermal energy storage (deep-ATES) is a technology that uses deep aquifer (> 500 m) as the thermal storage medium. Storage and recovery of thermal energy are achieved by extracting and injecting groundwater from deep aquifers through groundwater wells. Using geothermal energy as basic carrier, deep-ATES achieves balancing among multiple energy resources, and guarantees a steady supply of energy. Deep-ATES is an effective and critical technology for matching up heat supply and demand over time and space. In this paper, we presented a comprehensive review of the worldwide development of deep-ATES projects and summarized its thermal performance indicators. Thereby, we investigated the key processes and dominant hydrogeological and operational parameters controlling the thermal recovery efficiency of a deep-ATES system. We further discussed the technological bottlenecks in deep-ATES on the basis of previous researches. The last but not least, we evaluated and predicted the economic and market potentials of the deep-ATES system.

Key words: hot temperature aquifer thermal energy storage, thermal recovery efficiency, geothermal energy, hydrogeology, economical-potential
