  1. 16. Integrating Waste Heat from Hydrogen Production Into District Heating

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Fawzi Kayali; [2023]
    Nyckelord :Hydrogen; Electrolysis; Waste Heat Recovery; Combined Heat and Power Plant; District Heating; Simulation; Sustainable Heating Systems; Technology and Engineering;

    Sammanfattning : The aim of this research is to explore the feasibility of the integration of waste heat from electrolyzers within a Combined Heat and Power (CHP) plant and district heating (DH) network and suggest a practical setup for integration. With the escalating emphasis on the development of green hydrogen through electrolysis powered by renewable energy, a substantial amount of waste heat is generated, typically left unused. LÄS MER

  3. 17. Portfolio Strategies Under Different Inflationary Regimes

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Mohit Parkash; Diana Halladgi Naghadeh; [2023]
    Nyckelord :Inflation; Regression Analysis; Portfolio Optimization; Markowitz; Efficient Frontier; Asset Allocation; Portfolio Management; Financial Mathematics; Inflation; Regressionsanalys; Portföljoptimering; Markowitz; Effektiv Front; Tillgångsallokering; Portföljförvaltning; Finansiell Matematik;

    Sammanfattning : In 2023, the topic of ongoing inflation is being discussed almost daily as it has become inevitable. The global economy is facing significant uncertainty and downward pressure as several leading developed nations adopted expansionary fiscal policies and quantitative easing monetary policies during the pandemic.

  4. 18. Battery profit optimization

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Ebba Helfer; [2023]
    Nyckelord :Battery; 2nd life battery; Ancillary services; BESS; energy storage system; Technology and Engineering;

    Sammanfattning : In the near future, a new market will form full of 2nd life batteries that are no longer suitable to use in electric vehicles. This since their capacity retention is too low after a few years of usage, as a consequence of two aging mechanisms; cycling aging and calendar aging. LÄS MER

  5. 19. Techno-economic analysis and simulation of low temperature district heating networks

    Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Ilia Iarkov; [2023]
    Nyckelord :Low-temperature district heating; Modelica; BTES; LCA; LCC; Technology and Engineering;

    Sammanfattning : The continuous increase in global energy consumption has led to a greater focus on the energy required for heating buildings. This thesis presents a techno-economic model for analysing low-temperature district heating networks coupled with a geothermal heat source. LÄS MER

  7. 20. Energy retrofitting effect on perceived indoor climate: A case study of Estonian multi-family buildings

    Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Kadri Reinumägi; [2023]
    Nyckelord :Indoor environment; Thermal comfort; Indoor Air Quality; Window airing habits; Energy renovation; Occupant survey; Technology and Engineering;

    Sammanfattning : Energy renovations are an important measure for achieving the European Union’s target of climate neutrality by 2050. To meet the EU goal, Estonia needs to fully renovate 14 000 multi-family buildings by that time, affecting the indoor environment conditions of a large number of people. LÄS MER
