Large amount of thermal energy storage is essential for proceeding with further energy saving and contributing to environmental issues. The long term of weekly, monthly and seasonal thermal energy containment is useful to link between urban thermal energy demands and thermal energy sources-heat exhaust from industries, incinerations, power generations, air-conditioned buildings and other social infrastructures, and various natural heat sources such as seasonal warm and cold temperatures and solar energy. While we have to consider that we have both global limited resources-fossil fuel resources and environmental resources which is indispensable for human life, we have to continue our engineering efforts to establish the social structures of energy circulation by putting an energy source to joint use of industries and urban life through cascade use of thermal energy by each temperature level of thermal demands. Thus total energy consumption will be decreased among industries, social capitals and urban life. Now that huge thermal energy storage systems are not feasible to build on the ground, Underground thermal energy storage system (UTES) is one of the best effective solutions to the above issues, requiring us further engineering development about analysis technology on thermal analysis of underground soil behaviors and heat transfers, underground soil structure survey, underground thermal energy storage systems, low cost bore hole construction technology, underground heat exchanger technology, underground water movement control, more progressed heat pump technology, system integration of effective thermal energy consumption and storage types and peak load shavings, system operation and control technology and environmental evaluations. UTES is able to be combined with application of geo-thermal energy. Research and development efforts are continued to provide the solutions to above engineering subjects.
