  1. 1. Kraftvärmens förutsättningar för flexibel elproduktion i Sveriges elsystem - En kvalitativ analys

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

    Författare :Ylva Selander; Henrik Andersson; [2021]
    Nyckelord :Kraftvärme; flexibel elproduktion; systemtjänster; följsam värmeproduktion; Skåne; Danmark; CHP; Combined Heat and Power; flexible electricity production; ancillary services; flexible heat production; Skåne; Denmark; Technology and Engineering;

    Sammanfattning : This master thesis aims to investigate if and how Swedish Combined Heat and Power (CHP) plants can increase its flexibility in electricity production. This is examined through a combining analysis of technical, market-oriented and regulatory conditions for Swedish and primarily Skåne CHP plants, excluding autoproducers and industrial plants.

  2. 2. The Investigation and Modeling of the interaction between Paperboard Clippings in a Pipe Flow

    Master-uppsats, Lunds universitet/Institutionen för Energivetenskaper

    Författare :Lea Christierson; [2021]
    Nyckelord :Fluid-structure interaction; paperboard material modeling; transient pipe flow; overset mesh; image analysis; Technology and Engineering;

    Sammanfattning : In the manufacturing process of Tetra Pak packages, holes are cut out of the paperboard for straws and caps. The left-over paperboard clippings, called confetti, need to be evacu- ated from the machine. However, this evacuation process has proven to cause problems due to jams arising as the confetti get stuck in joints and along the pipe walls. LÄS MER

    Sammanfattning : The project that is presented in this report is the result of a master thesis for the Industrial Design Engineering programme at Luleå University of Technology. The project was conducted towards and together with the company Leosol during the fall of 2020. LÄS MER

  4. 4. Business Case, Design and Simulation of Solar Powered Hydrogen Refuelling Stations

    Master-uppsats, Lunds universitet/Institutionen för Energivetenskaper

    Författare :Axel Nordin Fürdös; [2021]
    Nyckelord :Hydrogen; HRS; Energy Systems; Technology and Engineering;

    Sammanfattning : Abstract The thesis investigates some possible pathways for how solar powered Hydrogen Refuelling Stations (Solar-HRS) can be implemented in a economically viable way. This is done by the use of a custom simulation model in MATLAB/Simulunk to simulate and evaluate the inner workings of the Solar-HRS. LÄS MER

    Sammanfattning : Background Nuclear reactors utilizing molten fuels rather than solid fuels show a massive advantage in energy yield, waste handling and safety features. The only successful reactor utilizing a molten fuel was called the ‘Molten Salt Reactor Experiment’ (MSRE), built and operated in the Oak Ridge national laboratory (ORNL) in Tennessee, U.S.A. LÄS MER
