Abstract

High-Temperature Aquifer Thermal Energy Storage (HT-ATES) can be used to reduce greenhouse gas emissions from heating. The thermal recovery efficiency is the main parameter indicating the performance of an HT-ATES system and it is influenced by multiple aquifer properties and storage characteristics. This study presents a method for estimating recovery efficiency through numerical modeling, data analysis, and curve fitting. This method shows the relation between the recovery efficiency and various storage conditions, such as aquifer properties and storage temperature. In addition, this research explores an analytical relationship between energetic efficiency and recovery efficiency and verifies that relationship with the generated data. The proposed method can be used for the purpose of initial screening to estimate the performance of an HT-ATES system and for efficiently using HT-ATES as a component in larger energy system models. This method uses the modified Rayleigh number in combination with aquifer thickness and injected volume and has a \(R^2\) of 85%. The analytical relation between energetic efficiency and recovery efficiency was shown to be accurate for all calculated energetic efficiency values above 60% and is less accurate with lower calculated energetic efficiency values.

分析估算高温含水层热能储存的效率

高温含水层热能储存（HT-ATES）可用于减少加热产生的温室气体排放。热采效率是表征热采系统性能的主要参数，受多种含水层性质和储集特性的影响。本文提出了一种通过数值模拟、数据分析和曲线拟合来估算采收率的方法。该方法揭示了采收率与含水层性质、储存温度等不同储存条件之间的关系。此外，本研究还探索了能量效率与采收率之间的解析关系，并用生成的数据验证了这种关系。所提出的方法可用于初始筛选，以估计HT-ATES系统的性能，并有效地将HT-ATES作为更大的能源系统模型的组成部分。该方法结合含水层厚度和注入体积，采用修正的瑞利数，其\(R^2\)值为85%. The analytical relation between energetic efficiency and recovery efficiency was shown to be accurate for all calculated energetic efficiency values above 60% and is less accurate with lower calculated energetic efficiency values.

期刊介绍： Geothermal Energy is a peer-reviewed fully open access journal published under the SpringerOpen brand. It focuses on fundamental and applied research needed to deploy technologies for developing and integrating geothermal energy as one key element in the future energy portfolio. Contributions include geological, geophysical, and geochemical studies; exploration of geothermal fields; reservoir characterization and modeling; development of productivity-enhancing methods; and approaches to achieve robust and economic plant operation. Geothermal Energy serves to examine the interaction of individual system components while taking the whole process into account, from the development of the reservoir to the economic provision of geothermal energy.
