There are several types of STES technology, covering a range of applications from single small buildings to community district heating networks. Generally, efficiency increases and the specific construction cost decreases with size. UTES (underground thermal energy storage), in which the storage medium may be geological strata ranging from earth or sand to solid bedrock, or aquifers. UTES technologies include:

Does seasonal thermal energy storage provide economic competitiveness against existing heating options?
Revelation of economic competitiveness of STES against existing heating options. Seasonal thermal energy storage (STES) holds great promise for storing summer heat for winter use. It allows renewable resources to meet the seasonal heat demand without resorting to fossil-based back up. This paper presents a techno-economic literature review of STES.
Can seasonal energy storage be economically viable?
To accommodate the use of this variable energy throughout the year the grid may benefit from economically viable seasonal energy storage to shift energy from one season to another. Storage of this nature is expected to have output durations from 500 to 1000 hours or more.
What are the different types of seasonal thermal energy storage facilities?
Currently, four main types of seasonal storage facilities are used: tanks, pits, boreholes, and aquifers . The characteristics of seasonal thermal energy storage concepts are presented in Table 1 [16, 17, 21, 22, 23, 24].
How does seasonal heat storage reduce energy losses?
Given that seasonal heat storage is based on sensible heat, the reduction in energy losses for large storage volumes and long storage periods is achieved through solutions placed in the ground, where the soil temperature variation is lower than the outside temperature variation.
