1. 1. Techno-Economic Analysis of Dye Separation in Textile Recycling

   Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Författare :David Lundberg; [2024]
   Nyckelord :Dye; Membrane filtration; Electrocoagulation; Techno-economic analysis; Pre-feasibility study; Technology and Engineering;

   Sammanfattning : This study determines the technical and economic feasibility of separating dye from a process filtrate in industrial textile recycling using electrocoagulation or sequences of membrane filtration with microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The lower requirements for treating this stream, compared to previously researched dyehouse effluents, left treatments not good enough for dyehouses viable for this process filtrate. LÄS MER

3. 2. Jämförelse mellan energilagringstekniker, samt dimensionering av batterier och vätgaslagring i off-grid system med solceller : En mjuk multikriterieanalys, samt skapandet av ett dimensioneringsverktyg som tillämpas på befintliga verksamheter

   Master-uppsats, Linköpings universitet/Energisystem

   Författare :Vendela Stenholm; Sara Sjödin; [2023]
   Nyckelord :;

   Sammanfattning : Elsystemet måste vara i balans mellan den el som produceras och den el som konsumeras, i varje sekund året om, för att undvika effektbrist. Risken för obalans i elsystemet ökar dock, delvis på grund av en ökad andel förnybar och intermittent elproduktion. LÄS MER

4. 3. Biochar and district heating : The path to negative emissions

   Kandidat-uppsats, Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

   Författare :Amanda Widlund; Thomas Norström; William Isaksson; Andreas Andersson; [2023]
   Nyckelord :biochar; pyrolysis; climate impact; carbon sink; district heating;

   Sammanfattning : Uppsala Kommun is developing a new city district called Sydöstra staden (SÖS) as an innovative and transformative city district. A technical supply system that aligns with the district’s goals is pyrolysis. Pyrolysis is a process where biomass is heated without the supply of oxygen. LÄS MER

5. 4. Methodology for Designing Bespoke Air Handling Units

   Master-uppsats, KTH/Energiteknik

   Författare :Alexandra Malysheva; [2023]
   Nyckelord :bespoke air handling unit; evaporative cooling system; two-stage crossflow heat exchanger; 3D-modeling; platsbyggt luftbehandlingsaggregat; evaporativt kylsystem; tvåstegs motströmsvärmeväxlare; 3D-modeling;

   Sammanfattning : This master's thesis explores the role of bespoke air handling units in enhancing energy efficiency in existing buildings. The context for the study is set against the backdrop of global initiatives, including the United Nations' Sustainable Development Goals, specifically Goal 7, which emphasizes the need to improve energy efficiency to combat climate change.

7. 5. Unlocking the Potential of Solar-Hydro Hybrid Solutions: Feasibility and Economic Analysis

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

   Författare :Måns Rosberg; [2023]
   Nyckelord :Hydropower; Solarpower; Hybrid power production; Solar-hydro hybrid power; Reservoir storage; Energy storage; Pumped hydro power; Floating PV; PV; Photovoltaics; Technology and Engineering;

   Sammanfattning : Hybrid solutions that combine multiple renewable energy sources, such as solar power and hydro power, are gaining popularity as a means of meeting the growing energy demands while minimising environmental impacts, but also as an opportunity of connecting solar power plants to the grid in areas where this might not be possible unless large investments are made. This master thesis aims to evaluate the feasibility and economic viability of integrating solar panels with an existing grid connection point at a hydro power plant, along with the introduction of an energy storage solution using a hydro power plant reservoir.
