  1. 1. Flexible Sector Coupling (FSC) of Electrical and Thermal Sectors via Thermal Energy Storage (TES) : A Case Study on Oskarshamn Energi

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

    Författare :Raúl Calvo García; Jose María Marín Arcos; [2023]
    Nyckelord :Flexible sector coupling FSC ; district heating DH ; thermal energy storage TES ; heat pump HP ; capacity optimization; dispatch optimization; open-access tools; Flexibel sektorkoppling; fjärrvärme; termisk energilagring; värmepump; kapacitetsoptimering; leveransoptimering; verktyg med öppen tillgång;

    Sammanfattning : The integration of distributed energy sources and systems is of high relevance for the transition towards a more sustainable energy system. Taking into consideration the  amount of emissions produced by the heating sector, which account for at least half of the energy demand in buildings, district heating systems have the potential to play a key role in the transition, by enabling the integration of various energy sources and provide flexible energy services to the grid.

    Sammanfattning : In response to the present and projected growth of the EV industry, the development of a large-scale, reliable and efficient lithium-ion battery recycling sector is vital to ensure circularity of the embedded valuable metals and ensure overall sustainability of the technology. One of the main recycling procedures under development is based on hydrometallurgy. LÄS MER

  3. 3. Techno-economic fesibility of a hybrid CSP (sCO2) - PV plant for hydrogen production

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

    Författare :Patricia Perez De La Calle; [2023]
    Nyckelord :Soec oxide electrolyzer cell SOEC ; Concentrated solar plant CSP ; Super critical cO2 sCO2 ; photovoltaic field PV ; Thermal storage TES ; electrolyzer; MoSES; high temperature electrolysis THE .;

    Sammanfattning : The global need to eliminate CO2 emissions and its consequent reduction in the use of fossil fuels drives the ongoing energy transition that highly involves the research achievements of the scientific community to reach the goals of this purpose. Renewable sources like photovoltaic and wind energy, are central to this endeavor, however, the intermittency of natural resources makes it non-dispatchable and energy storage is fundamental.

  4. 4. Study of demolition processes for prestressed concrete bridges: Kalix bridge

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Lundin Hanna; [2022]
    Nyckelord :Kalix bridge; demolition methods; demolition process; FEM analysis; Kalixbron; rivningsmetoder; rivningsprocesser; FEM analys;

    Sammanfattning : Bridges in Sweden are getting older and some of them are reaching their designed life span. With an older generation of bridges, the need for a good understanding of demolition processes increase. The Kalix bridge is planned to be demolished and will be used as a case study in this thesis.
