摘要:

深层含水层储热是一种利用深度>500 m的深层含水层作为储热介质的储热技术,储热对象通常为50~150 ℃的热水。它通过地下水井从深层含水层中抽取和灌入地下水,实现热能储存和回收。深层含水层储热技术是弥补能源供需时空分布的不平衡,综合利用多种可再生能源,实现节能减排的有效途径,是国内外研究的前沿和热点。文中首先阐述了深层含水层储热系统在世界范围内的历史发展,归纳储热系统的热工性能,在总结前人研究工作的基础上分析影响其热回收效率的关键参数,并对各个参数对热回收效率的敏感性做了综述。在此基础上,本文还讨论了限制深层含水层储热系统发展的技术瓶颈,并针对系统的经济效益和市场潜力做了预测和展望。

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
