Sensible heat storage take advantage of [[sensible heat]] in a material to store energy.<ref>Layered Materials for Energy Storage and Conversion, Editors: Dongsheng Geng, Yuan Cheng, Gang Zhang, Royal Society of Chemistry, Cambridge 2019,</ref>

[[Seasonal thermal energy storage]] (STES) allows heat or cold to be used months after it was collected from waste energy or natural sources. The material can be stored in contained aquifers, clusters of boreholes in geological substrates such as sand or crystalline bedrock, in lined pits filled with gravel and water, or water-filled mines.<ref name=TES_BIES/> Seasonal thermal energy storage (STES) projects often have paybacks in four to six years.<ref name="Hellström" /> An example is [[Drake Landing Solar Community]] in Canada, for which 97% of the year-round heat is provided by solar-thermal collectors on garage roofs, enabled by a borehole thermal energy store (BTES).<ref name="Wong" /><ref name="DistrictEnergy.org-a" /><ref>[http://www.nrcan.gc.ca/media-room/news-release/2012/6586 Canadian Solar Community Sets New World Record for Energy Efficiency and Innovation] {{Webarchive|url=https://web.archive.org/web/20130430221347/http://www.nrcan.gc.ca/media-room/news-release/2012/6586 |date=April 30, 2013 }}, Natural Resources Canada, October 5, 2012.</ref> In Braedstrup, Denmark, [[Solar power in Denmark|the community's solar district heating system]] also uses STES, at a temperature of {{convert|65|C}}. A [[heat pump]], which runs only while surplus wind power is available. It is used to raise the temperature to {{convert|80|C|F}} for distribution. When wind energy is not available, a gas-fired boiler is used. Twenty percent of Braedstrup's heat is solar.<ref name="Solar District Heating" />
