1. 1. 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. 2. 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.

4. 3. Intermediate-mass black hole binary as an origin of super-massive black holes

   Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Författare :Isabelle Signe Maj Maria Thord; [2023]
   Nyckelord :Intermediate-mass black holes; binary; merger; hardening; encounters; Physics and Astronomy;

   Sammanfattning : Galactic nuclei contain super-massive black holes (SMBHs), nuclear stellar clusters (NSCs), or both. In the NSC, intermediate-mass black holes (IMBHs) are likely to reside and form highly eccentric binaries. Over time, the orbit of a binary could harden via interaction with surrounding low-mass stars. LÄS MER

5. 4. Utvärdering av artificiell syresättning i syrefria bottenvatten och modellering av fjärden Slätbaken

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Arvid Jonsson; [2023]
   Nyckelord :Artificial oxygenation; Geo-engineering; oxygenation; Slätbaken; mass-balance modelling; oxygen demand; Artificiell syresättning; syresättning; syrgasnedpumpning; Slätbaken; massabalansmodellering; syrebehov;

   Sammanfattning : Östersjön är idag det system med störst utbredning av syrefattiga eller syrefria bottnar i hela världen. Problemet har uppstått som följd av den massiva näringsbelastning från de kringliggande länderna som pågått sedan industrialiseringen intensifierades på 1900-talet. LÄS MER

7. 5. Developing an Automated System for Yeast Culture Cultivation and Control using Flow Cytometry

   Master-uppsats, Lunds universitet/Teknisk mikrobiologi

   Författare :Sara Magnusson; [2023]
   Nyckelord :Yeast; flow cytometry; applied microbiology; Technology and Engineering; Biology and Life Sciences;

   Sammanfattning : Flow cytometry is a versatile tool for monitoring a microbial population at a single-cell level. Multiple parameters can be monitored based on the users’ requirements through the utilization of different dyes, biosensors etc. LÄS MER
