Please note! Course description is confirmed for two academic years, which means that in general, e.g. Learning outcomes, assessment methods and key content stays unchanged. However, via course syllabus, it is possible to specify or change the course execution in each realization of the course, such as how the contact sessions are organized, assessment methods weighted or materials used.

CONTENT, ASSESSMENT AND WORKLOAD

Content

  • valid for whole curriculum period:

    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:

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