  1. 16. Comparing the Effects of Flexibility Options on Conventional and Low-temperature District Heating Networks : Studying the potential of the next generation of district energy systems

    University essay from KTH/Energiteknik

    Author : Mario Nithyanathan; [2022]
    Keywords : District heating DH ; low-temperature district heating LTDH ; 4GDH; Flexibility; Thermal energy storage TES ; Optimization; Modelling; Fjärrvärme; Låg-temperatur fjärrvärme; 4GDH; Flexibilitet; Termisk energilagring TES ; Optimering; Modellering;

    Abstract : District heating (DH) systems have been commonplace in Europe for over a century. These systems have undergone an evolution since their conceiving, and today we are at the precipice of the next major transition from the third-generation district heating system (3GDH) to the fourth generation (4GDH).

  2. 17. Implementation of large-scale heat storage of excess heat in Växjö´s combined heat and power plant. : A techno-economic analysis

    University essay from Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Author : Parit Chandrasardula; [2022]
    Keywords : CHP plant; Excess heat; Borehole Energy storage; Lake Source Cooling;

    Abstract : To achieve greater economic stability, CHP plant operators such as VEAB from Växjö are motivated to search for a new business model that are compatible with their existing facilities while also contribute to increasing the overall revenue of the company. These processes include hydrogen production and biochemical products such as biopolymer and biofuels. READ MORE

  3. 18. Electron Backscatter Diffraction (EBSD) Analysis and Predicted Physical Properties of Shocked Quartz from the Chicxulub Impact Crater, Mexico

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Erina Prastyani; [2022]
    Keywords : EBSD; SEM; shocked quartz; quartz; CPO; seismic velocity; anisotropy; Chicxulub; impact crater; pole figures; MTEX toolbox; microstructural features; planar deformation feature; planar fracture; feather features;

    Abstract : As one of the most common minerals in crustal rocks, quartz has been widely used as an indicator for shock metamorphism. Shocked quartz is found in the Chicxulub impact crater, an impact crater that has been linked to the Cretaceous-Tertiary extinction ~66 million years ago. READ MORE

  4. 19. Data center cooling solutions : A techno-economical case study of a data center in Sweden

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Joel Sjökvist; Fredrik Magnusson; [2022]
    Keywords : Energy systems; Data center cooling; Free cooling; Air cooling; Geothermal cooling; Mechanical cooling; District cooling; Building conversion; Dry cooler; Cooling machine; Borehole; PUE;

    Abstract : Given the coinciding growth-trend in the production of consumer electronics and generation of data, the increase in server halls and data centers, as a means for hosting storage capacity for the generated data, has been prominent over the last decades. The establishment of data centers in already existing infrastructure can entail major changes in terms of energy system design. READ MORE

  5. 20. Energy Usage in Railway Wayside Object Heating : Modeling of melting of Ice, Estimation of heating power requirement in Switch and Renewable energy feasibility for a Railway system

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Sidharth Kapoor; [2022]
    Keywords : Melting of Ice; Numerical modeling; Transient conjugate heat transfer; Transient analysis; CFD; Switch heating; Heat pumps in Railways; Issmältning; Numerisk modellering; Transient värmeöverföring; Transientanalys; CFD; Värmepumpar i järnvägar;

    Abstract : Trafikverket operates about 12000 Switches and crossings (SnCs) of which 6800 are equipped with an electrical heating system of 10−30kW power to keep SnCs functional throughout the winters by keeping them free of Snow/Ice. The energy consumption is approximately 200−130GWh/year costing approximately 10−15 million Euros annually. READ MORE
