1. 1. Implementering av fjärde generationens fjärrvärme i svenska fjärrvärmenät : En fallstudie på Borlänges fjärrvärmenät

   Master-uppsats, Linköpings universitet/Energisystem

   Författare :Henrik Nordström; Klara Smeds; [2021]
   Nyckelord :4GDH low temperature district heating; 4GDH lågtempererad fjärrvärme;

   Sammanfattning : För att möta problem med ökande klimatförändringar kan fjärrvärmen ha en betydande roll ur både en svensk och en internationell kontext. Samtidigt står svenska fjärrvärmebolag inför betydande utmaningar då värmepumpar blir ett allt vanligare val för att möta uppvärmnings- och tappvarmvattenbehovet, tillgången till avfall och biomassa som bränsle förutspås bli mer begränsad och byggnaders uppvärmningsbehov blir allt lägre.

3. 2. Keeping the (Waste) Heat in the City

   Master-uppsats, Lunds universitet/Internationella miljöinstitutet

   Författare :Romy Kölmel; [2020]
   Nyckelord :waste heat recovery; district heating; energy governance; governance instruments; modes of governance; Law and Political Science; Social Sciences;

   Sammanfattning : The recovery of ‘waste heat’ from industrial and urban processes could meet a significant share of heating demands in urban and semi-urban areas. Replacing conventional heat sources in district heating (DH) systems with recovered heat could decrease primary energy inputs in a sector that globally relies to 90% on fossil fuels. LÄS MER

4. 3. Cleantech Investments in China – Multiple perspectives on the trends, drivers and barriers

   Master-uppsats, Lunds universitet/Internationella miljöinstitutet

   Författare :Tim Forslund; [2017]
   Nyckelord :Cleantech; China; investments; trends; drivers and barriers.; Earth and Environmental Sciences;

   Sammanfattning : Cleantech—technologies with a reduced environmental impact—has emerged as an important set of solutions for addressing pollution and its impacts in China. The goal of this study is to map out wherein Chinese actors with first-hand knowledge of cleantech investments think the largest domestic investment opportunities are found, understand the underlying reasons, and then evaluate how consistently the investment preferences reflect the country’s environmental problems, public discourse and policy.

5. 4. Comparative Study of Different Organic Rankine Cycle Models: Simulations and Thermo-Economic Analysis for a Gas Engine Waste Heat Recovery Application

   Master-uppsats, KTH/Kraft- och värmeteknologi

   Författare :Tihomir Rusev; [2015]
   Nyckelord :ORC; Waste Heat Recovery; Aspen Plus; Cascaded Cycle; Thermo-Economic; ORC Simulations; ORC Models; ORC Model Comparisons; Gas Engine Waste Heat Recovery; Hot Exhaust Gases; Multiple Waste Heat Sources; ORC Waste Heat Power Generation; Heat and Power; Combined Cycle; Siloxane;

   Sammanfattning : Increasing the efficiency of conventional power plants is a crucial aspect in the quest of reducing the energy consumption of the world and to having sustainable energy systems in the future. Thus, within the scope of this thesis the possible efficiency improvements for the Wärtsilä 18V50DF model gas engine based combine power generation options are investigated by recovering waste heat of the engine via Organic Rankine cycle (ORC).
