1. Jetbrandtester och vätgas : En litteratur- och intervjustudie om försök med vätgasjetflammor
Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Vätgas är en energibärare som kan vara en av pusselbitarna i omställningen till en mer klimatneutral värld. Infrastrukturen byggs ut, industrin växer och vätgasfordon blir vanligare. LÄS MER
2. Assessment of the energetic feasibility of a novel CHP biorefinery concept
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : This study investigates the potential for energetic self-reliance in an integrated biore- finery, the Earth Power Lodge (EPL), which aims to convert waste into valuable by- products through bio- and thermochemical conversion processes. The primary questions addressed include assessing the necessity of external propane to sustain the pyrolysis process and the net energy output of the ThermoChemical Reactor (TCR) process when fractional distillation is applied to the resulting bio-oils.

3. Design of Experiment Based on Full Factorial CFD Spray Modelling
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : Design of experiment is a powerful tool that can reduce the amount of physical testing needed to save resources, time and money. A CFD-setup was constructed in OpenFOAM-8, simulating injection of liquid propane with a standard multi-hole injector. The model was then validated against experimental results. LÄS MER
4. Comparative Analysis of Modern Energy Systems for Ice Rinks
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Ice rinks are highly energy-intensive commercial buildings with an average annual energy consumption of 1,000 MWh, most of it being used to cover the simultaneous heating and cooling demands. The aim of this thesis is to find the most energy efficient energy system for ice rinks by evaluating different system modifications and refrigerants. LÄS MER
5. Investigation of new refrigerants for a large-scale heat pump and evaluation of system performance
Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : Heat production accounted in 2021 for 50 % of the energy end use globally, where a strongconnection to fossil sources still exists. Large-scale electrical heat pumps can therefore have akey role in the energy system to enable a decreased reliance on fossil fuels and at the same timecontribute to stable system when incorporating more intermittent renewable sources.
