  1. 1. Techno-economic analysis and simulation of low temperature district heating networks

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Ilia Iarkov; [2023]
    Keywords : Low-temperature district heating; Modelica; BTES; LCA; LCC; Technology and Engineering;

    Abstract : 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. READ MORE

  3. 2. The Operational Strategy Optimization of Distributed Energy System Based on MATLAB : A case study in Northeast China

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Yujun Han; [2023]
    Keywords : Distributed Energy System; CCHP; operational strategy; Distribuerat energisystem; CCHP; operativ strategi;

    Abstract : China is the largest energy consumer worldwide, with a fast-growing rate. But the energy and environmental problems brought by its unbalanced energy structure and low energy efficiency restrict the sustainable development of China. The Distributed Energy System (DES) is one of the internationally recognized solutions to the problems. READ MORE

  4. 3. Rising Heat, Rising Risk: The Effect of Greenhouse Gas Emissions on Downside Tail Risk

    University essay from Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Author : Moritz Neuber; Fabrice Van Lancker; [2023]
    Keywords : Climate Risk; Downside Risk; GHG Emissions; Tail Risk; Sustainable Finance;

    Abstract : Regulatory and societal attention to environmental pollution is increasing, and greenhouse gas (GHG) emissions are becoming a potential risk factor for investors. This paper uses panel data from S\&P 500 firms between 2015 and 2022 to investigate the link between GHG emissions and downside tail risk. READ MORE

  5. 4. Simulation and Experimental Based Hardenability Evaluation of Chromium Alloyed Powder Metal Steels

    Abstract : Powder metallurgy is a branch of metal forming technology where metal powders are used to manufacture parts and components. It is a flexible and economical technique for manufacturing complicated shapes. This present work focuses on press and sinter technology and forms a part of Höganäs’s efforts of modelling hardenability through quenching. READ MORE

  6. 5. The transition of reaction-to-fire behavior from biomass to corresponding biochar

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Jacob Johansson; [2023]
    Keywords : biochar; biomass; heat release rate; reaction-to-fire;

    Abstract : As of now, the environmental issue is very topical and there is also an underutilization of different biological material where these can be used in ways that are typically not thought of. One way to increase the degree of utilization is to convert various biomasses such as natural rubber, olive pits, wood chips, and reed pellets into biochar. READ MORE
