1. 16. 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. 17. 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

4. 18. Urban flood risk mitigation : A perspective form urban planning

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

   Författare :Andreas Brandow; [2023]
   Nyckelord :Urban indicators; Resilience; Urban flooding; Flood protection and mitigation; Luleå;

   Sammanfattning : Due to the global warming and climate change, an increased frequency of high intensity rains and other disasters are expected all around the world. To predict this change in climate the IPCC has created a set of climate scenarios, RCPs, that will try to predict the future climate based on how much we are able to adapt and mitigate the effects we as a species have on the environment.

5. 19. Analyzing Raw Material Characteristics for Composite and Bio-composite preparation and Assessing Environmental Impacts through LCA

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Lakshay Vashist; [2023]
   Nyckelord :Plastic; Polymers; Composites; Bio-composites; Synthetic Fibers; Natural Fibers; Mechanical Properties; Life Cycle Assessment LCA ; Plast; polymerer; kompositer; biokompositer; syntetiska fibrer; naturliga fibrer; mekaniska egenskaper; livscykelanalys LCA ;

   Sammanfattning : With the population expected to grow dramatically in the future. The existing state of the ecosystem appears to be worse in the future. One of the key culprits that has been wreaking havoc on the ecosystem is the use of plastic that is used to produce composites. LÄS MER

7. 20. Circular economy: : Sustainability assessment of circular business models basedon material flow analysis.

   Master-uppsats, Mittuniversitetet/Institutionen för naturvetenskap, design och hållbar utveckling (2023-)

   Författare :Sara Ankar; [2023]
   Nyckelord :Circular economy; Circular business models; Product-Service-System; Profitability; Climate impact; Material Flow Analysis;

   Sammanfattning : This study has contributed to the developing concepts of circular economy by assessing circular business models and to test different approaches for circularity in a measurable way. In our current era of time, we stand against environment challenges with a warming planet and resources scarcity. LÄS MER
