1. 1. Improvement of anautomatic networkdrawing algorithm in thecontext of utility networks

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

   Författare :Hyacinthe Ménard; [2024]
   Nyckelord :District Heating Network; Mathematical Optimization; Python; Fjärrvärme; Optimeringslära; Python;

   Sammanfattning : The European Union’s ambitious climate targets necessitate substantial reductions in greenhouse gas emissions, particularly within the heating and cooling sector, which accounts for a significant portion of energy consumption. District Heating and Cooling (DHC) systems emerge as a key solution for decarbonizing this sector by enabling high efficiency heat production and the integration of renewable and carbon-neutral energy sources.

3. 2. 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

4. 3. Emission factors and methods used in climate impact assessments of energy use in Swedish heated buildings - Assessing district heating and electricity as energy source

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

   Författare :Louise Piltz Vitanc; Matilda Hinsegård; [2023]
   Nyckelord :Life Cycle Assessment; Climate Calculation; Methodology; B6; Global Warming Potential; Technology and Engineering;

   Sammanfattning : When the property- and building industry moves towards new solutions targeting reduced climate impact, this puts pressure on the building owners and companies to calculate the climate impact of buildings. It may seem easy, but there are various methods and guidelines to navigate around. LÄS MER

5. 4. 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. 5. Methodology for Stored Heat “Heat In Place” (HIP) assessment of geothermal aquifers – Exemplified by a study of the Arnager Greensand in SW Scania

   Master-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Oskar Sundberg; [2023]
   Nyckelord :geothermal energy; geothermal resource assessment; geothermal potential; volume method; volumetric method; recovery factor; direct use; direct heat; Mesozoic aquifers; Earth and Environmental Sciences;

   Sammanfattning : In the sedimentary bedrock of southwest Scania, located in the southernmost part of Sweden, there are several low-enthalpy Mesozoic sandstone aquifers situated at different depths. These aquifers collectively hold the potential for direct-heat geothermal utilization. LÄS MER
