| 英文摘要 |
The technologies of underground thermal energy storage (UTES) including GSHP, ATES and BTES have been widely used in the EU countries. The objective of this project is to collect the latest foreign developing status and related policy incentives of UTES for developing the "Low carbon sustainable homeland" policy by Taiwan EPA. The 3E principle assessment model was used to evaluate the suitable technologies on conventional refrigeration/heat pump system, GSHP, ATES and BTES which may be used in Taiwan. Three underground storage expert forums were held to share experiences from an UTES expert, Dr. Kirsti Midttømme, visiting European UTES sites and discussing the direction of development in the future. The report presents some obstacles including institutional, regulatory, technological and financial barriers for the development of UTES in Taiwan. In addition, some implementation strategies and suggestions are proposed to Taiwan EPA for the development of UTES.
