  1. 11. Optimering av last och produktion i Gävles fjärrvärmenät : Reducering av effekttoppar via värmelagring i byggnader

    Kandidat-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Fredrik Elofsson; [2019]
    Nyckelord :District heating; load management; peak shaving; heat load reduction; thermal storage; smart energy system; Fjärrvärme; laststyrning; effekttoppar; värmelagring; smarta energisystem;

    Sammanfattning : District heating is today the most common way of providing a building with heat and hot water in Sweden. It is an environmentally friendly product mostly used with renewable fuel. However, at power peaks most companies use production units that are more expensive and worse for the environment and should therefore be avoided as much as possible. LÄS MER

  3. 12. Thermal Performance Analysis of High Temperature Borehole Thermal Energy Storage Design from an Insulation Perspective

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Tobias Magnusson; Joel Ljunggren; [2019]
    Nyckelord :High Temperature Borehole Thermal Energy Storage; HT-BTES; Thermal Energy Storage; TRNSYS; Technology and Engineering;

    Sammanfattning : Thermal energy storage is a growing concept within the sector of energy production. The concept is based on storage of excess thermal energy, for usage during high demand, as a mean of reducing the need for new production. LÄS MER

  4. 13. Environmental assessment of combined heat and cold production plants for district thermal networks, through optimization methods

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Robin Roure; [2019]
    Nyckelord :;

    Sammanfattning : With the international commitment behind the Paris Agreement, district thermal networks’ contribution to final energy demand are bound to increase as they allow significant emission savings. In addition to that, the cooling demand is expected to increase significantly in the coming years. LÄS MER

  5. 14. Developing a Bottom Up Cost Calculation Model and Methodology for Thermal Storage Applications

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Thomas Li; [2019]
    Nyckelord :Thermal Storage; Bottom up cost calculation; Methodology; Molten Salt; CSP; Ice thermal Storage;

    Sammanfattning : Increasing storage for energy is one of the most important challenges today to overcome in order to enable higher penetration of renewable energy in the existing energy systems. Thermal storage is one category of energy storage that has been successfully demonstrated in a number of engineering projects and is showing promising potential in the future. LÄS MER

  7. 15. Kostnadsanalys av investering i en fjärrvärmeackumulator : Ett underlag för beslut om utökade lagringsmöjligheter vid Bomhus Energi

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik

    Författare :David Svedinger; [2019]
    Nyckelord :fjärrvärme; värmelagring; ackumulator; återbetalningstid;

    Sammanfattning : The district heating system of Gävle will within a few years likely undergo changing routines in production and a rising demand for heat, which will increase the need for flexibility and availability in the production units. It is therefore relevant to study the economic potential of installing a thermal storage at the largest production unit in the system; Bomhus Energi. LÄS MER
