  1. 1. Assessment of the integration of solar heat power into food drying processes

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Charalampos Psilopoulos; [2023]
    Nyckelord :Sustainable; sustainability; co2 reduction; feasibility; solar thermal; direct steam generation; drying; food industry; scope 1 emissions; sdg; sustainable development goals; spray drying; drum drying; powder; food; Technology and Engineering;

    Sammanfattning : The long-lasting usage of fossil fuels has brought its negative impact on the planet and thus the society is turning towards more environmentally sustainable solutions in every aspect of life. This master’s thesis discusses the novel topic of integrating concentrated solar thermal collectors, which directly produce steam, to drying processes in the food industry, which is proven to currently emit significant amounts of Greenhouse Gases (GHGs).

  3. 2. Investigation of new refrigerants for a large-scale heat pump and evaluation of system performance

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Hanna Grahn; Matilda Eriksson; [2023]
    Nyckelord :Large-scale heat pump; refrigerant; COP;

    Sammanfattning : Heat production accounted in 2021 for 50 % of the energy end use globally, where a strongconnection to fossil sources still exists. Large-scale electrical heat pumps can therefore have akey role in the energy system to enable a decreased reliance on fossil fuels and at the same timecontribute to stable system when incorporating more intermittent renewable sources.

  4. 3. Refrigerant Selection for District Heating’s Large-scale Heat Pumps

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

    Författare :Görkem Balyaligil; [2023]
    Nyckelord :heat pump; district heating; refrigerant; natural; synthetic;

    Sammanfattning : The global demand for heat as the primary source of final energy underscores the urgency of decarbonizing the heating sector to foster sustainability. Heat pumps are crucial in achieving sustainability, particularly in district heating applications, offering efficient centralized heating solutions. LÄS MER

  5. 4. Utilization of waste heat from hydrogen production : A case study on the Botnia Link H2 Project in Luleå, Sweden

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Andrea Miljanovic; Fredrik Jonsson; [2022]
    Nyckelord :PEM electrolyzer; alkaline electrolyzer; waste heat; district heating; LCOH;

    Sammanfattning : The global hydrogen demand is steadily increasing, and one way of accelerating the green hydrogen supply is to stimulate the green hydrogen economy. Utilization of waste heat from hydrogen production can increase the profitability of produced green hydrogen. LÄS MER

  7. 5. Intern användning och export av Cytivas spillvärme

    Kandidat-uppsats, SLU/Dept. of Energy and Technology

    Författare :Mohamad Karam Alhomsi; John Bankefors; Tanapon Bredin; Malko Riche; Tim Selin; Henrik Sollenberg; [2022]
    Nyckelord :spillvärme; industri; fjärrvärme; kylsystem; värmepump;

    Sammanfattning : Today there is a big potential in recycling waste heat at large-scale production sites. In this report the ability to reuse heat from Cytiva’s industrial facilities C7, C8 and C9 located in Uppsala is examined. The purpose is to analyze the need of heat for two on-site buildings and how the buildings will be provided by waste heat. LÄS MER
