Course description

Content
This course introduces system level approach to thermal energy storage (TES), considering the fundamentals of TES, and how it can improve the sustainability of energy systems. TES is introduced by assessing the need for its application, including

excess heat from industrial and energy sector installations, production and demand mismatch (especially with RES production) and the role of consumer side incentive such as dynamic electricity and heat tariffs. A common approach is taken to all TES technologies emphasizing the importance of temperatures and timescale (seasonal vs short term). The use of TES at different levels is then assessed as follows:

  • Power plants, Industrial level, including use of DH network for storage
  • Community level e.g. ATES, BTES, CTES, PTES
  • Buildings e.g. Thermal mass, phase change materials, Chemical storage, DSM with HP ground heat storage (rock/soil)
