Material and component development for thermal storage systems

    Project Details


    The aim of the PhD project is to develop economically attractive compact long term heat storage for different applications.

    Content of the project:
    Focus will be on the three fields: Component development, applications and numerical methods. In this way the suitability of compact long term heat storages can be elucidated for different applications.

    Activities in the PhD study will be:
    a) Participation in the IEA Task 58 project ‘Material and component development for thermal storage systems’ which will be carried out in 2018-2019.
    b) Research activities will be focused on development of a compact heat storage based on stable super cooling of salt hydrate and on optimization and integration of the developed heat stor-ages into the future energy system. Simulation models will be developed, validated and used in the investigations.
    c) Another focus of the project is on development and test of an economically attractive com-pact long term heat storage and on investigation of potential applications of the storage units in collaboration with companies.

    The project will be co-financed by the Chinese Scholarship Council fund, the EUDP supported IEA Task 58 ‘Material and component development for thermal storage systems’ and Department of Civil Engineer-ing, Technical University of Denmark.

    Key findings

    The project will result in a heating system with a long term heat storage that is significantly better than water based systems.
