Helsinki, Finland, Dec. 19, 2018 (GLOBE NEWSWIRE) -- Former fuel-oil storage caves in the Helsinki bedrock will store hot water heated in the processes of the Helsinki energy company Helen, to be ...
Abstract. Traditional air-conditioning systems are energy-intensive and contribute to severe environmental pollution. Despite these drawbacks, traditional air conditioners grow increasingly popular in rapidly expanding rural villas, exacerbating environmental concerns. It is very important to develop new technology that may …

There are distinct classifications in energy storage technologies such as: short-term or long-term storage and small-scale or large-scale energy storage, with both classifications intrinsically linked. Small-scale energy storage, has a power capacity of, usually, less than 10 MW, with short-term storage applications and it is best suited, for …
Underground Thermal Energy Storage (UTES) systems are used to buffer the seasonal difference between heat and cold supply and demand and, therefore, represent an interesting option to conserve energy. Even though UTES are considered environmental friendly solutions...

Underground thermal energy storage (UTES) is a technique for storing thermal energy that makes use of the subsurface to store both heat and cold. This chapter discusses a …
Underground thermal energy storage (UTES) is a form of energy storage that provides large-scale seasonal storage of cold and heat in natural underground sites. [3-6] There exist thermal energy supplying systems that use geothermal energy for cooling and heating, such as the deep lake water cooling (DLWC) systems which extract naturally cooled …
Two differing well designs are used to facilitate thermal storage in aquifers. Multi-well systems use one or more sets of well doublets within the aquifer to store thermal energy at spaced lateral points separating hot and cold [22].Mono-well …
In order to overcome the intermittent nature of renewable energy resources, borehole thermal energy storage (BTES) systems are found to be a feasible option these days. Citation: Abbas, Z.; Abbas ...
Details on thermal storage types, operation, and applications are provided, for both heat and cold storage. The main thermal storage types, sensible, latent, and thermochemical, are covered. A focus is placed on underground thermal energy storages, which normally are sensible storages, as they can store both hot and cold …
Low-carbon energy transitions taking place worldwide are primarily driven by the integration of renewable energy sources such as wind and solar power. These variable renewable energy (VRE) sources …
