  4. 4. Assessment of calculation methods for Primary Energy Factors : Case Study of Swedish electricity mix

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Javier Ferrero Andrés; [2022]
    Nyckelord :Primary Energy; Primary Energy Factor; Calculation methods; Partial Substitution; Exergy; Physical Energy Content;

    Sammanfattning : The use of the concept of "primary energy" is present in all types of regulations at both European and national level, so that all aspects related to the reduction of energy use and energy efficiency measures speak in terms of primary energy and Primary Energy Factors, necessary for its conversion. The existing consensus on the use of the term is not such in terms of the methodology for calculating the Primary Energy Factors to be adopted, which is the reason for the search for a methodology that acquires the status of global and standard.

  5. 5. Performance Evaluation of a High Temperature Borehole Thermal Energy Storage Under Influence of Groundwater Flow

    Master-uppsats, KTH/Energiteknik

    Författare :Max Hesselbrandt; [2021]
    Nyckelord :;

    Sammanfattning : Recent years have seen a growing interest in large-scale high-temperature borehole thermal energy storage (HT-BTES) as a means to store industrial waste heat and solar energy between the seasons. A profound understanding and characterization of the thermal and hydraulic processes involved in such systems is required for the optimal design as well as for environmental assessments of the storage.
