Abstract
Borehole Thermal Energy Storage (BTES) systems have emerged as pivotal low‐carbon solutions for seasonal thermal energy storage in the transition to sustainable energy systems. This work presents a comprehensive analysis of 75 documented BTES installations worldwide. Advanced Geographic Information System (GIS) tools have been employed to create the first geodatabase of BTES installation locations and characteristics, a pioneering achievement in the field. The study elucidates the operational principles of BTES systems, categorizes them by temperature and energy source, and examines key design factors such as array geometry, charging and discharging rates, and thermal conductivity. Several graphs effectively demonstrate the real-world performance of operational BTES plants. Additionally, this research analyses and compares various numerical modelling software used in BTES design, evaluating their performance, accuracy, and utilisation. Incorporating additional data remains essential to expand current knowledge and fully harness the potential of open-access information. This research delivers novel insights into both the theoretical and practical aspects of BTES technology. It provides valuable contributions with wide-ranging applications and implications for both researchers and companies. By promoting the integration of open-access data and encouraging technological advancements, this work significantly advances our understanding of BTES systems and supports their continued deployment and optimization within sustainable energy solutions.Pubblicazioni consigliate
