  1. 1. Energy System Analysis of thermal, hydrogen and battery storage in the energy system of Sweden in 2045

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

    Author : Poornima Sundarrajan; [2023]
    Keywords : VRES; Energy System Model; CEEP; Wind integration; Thermal Energy Storage; Hydrogen Storage; Heat Pumps; Electrolysers; VRES; Energisystemmodell; CEEP; Vindintegration; Värmeenergilagring; Vätgaslagring; Värmepumpar; Elektrolysörer;

    Abstract : Sweden has goals to reach net-zero emissions by 2045. Although electricity sector is almost fossil free, industry & transport still rely on fossil fuels. Ambitious initiatives such as HYBRIT, growth of EV market & expansion of wind power aim to expedite emission reduction. READ MORE

  3. 2. Optimal dead space in axial-type expander

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Martin Karman; [2022]
    Keywords : Dead space; Expander; Steam engine; Tolerance analysis; Axial-kolvmotor; Effektivitet; Expansionskammare; Kolv; Ångmotor;

    Abstract : In this thesis a method for determining optimal dead space in an axial-type expander is developed. The axial-type expander in question is for use in a steam engine, a environmental friendly and fuel-agnostic alternative to the ICE-engine. READ MORE

  4. 3. Characterizing coil windings noise due to compressive fault currents : A study to determine if there is a characteristic noise from transformer windings due to fault currents

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Simon Lundgren; [2022]
    Keywords : Transformer windings; short circuit forces; current pulses; microphone; Comsol Multiphysics; FFT; Transformator lindningar; strömpulser; mikrofon; kortslutingskrafter; Comsol Multiphysics; FFT;

    Abstract : Transformers are essential for modern power distribution system. They are efficient and enable the voltages to be transformed up for transportation of electricity and back down for consumer use. The reliability of the transformer is affected by faults and fatigue of the copper. READ MORE

  5. 4. Optimizing Control Algorithm for Indirect Liquid ThermalManagement of Batteries : A Study Executed at Northvolt

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

    Author : Mantas Petrosius; [2021]
    Keywords : ;

    Abstract : The vast expansion of intermittent sustainable energy generation has favoured a gradual adoption of lithium-ion batteries in various industrial and automotive applications. Despite its many inherent merits, this storage technology is very vulnerable to temperature variations: the performance and lifespan of LIBs are substantially influenced by their load cycles, thermal behaviours, and operating temperature range.
