1. Hydrogen storage systems : Methodology and model development for hydrogen storage systems performance evaluation based on a transient thermodynamic approach
University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknikAbstract : The overall performance of a hydrogen storage system can be affected by various parameters, such as operation and design parameters, but also by the state of the hydrogen contained inside the storage tanks. In this work, a methodology is developed to evaluate the state of the hydrogen during the filling process and its impact on the overall system performance under variable operation conditions and design parameters.

2. Investigation of new refrigerants for a large-scale heat pump and evaluation of system performance
University essay from Linköpings universitet/Mekanisk värmeteori och strömningsläraAbstract : 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.

3. Modelling the global water cycle – the effect of Mg-sursassite on the amount of globally subducted water
University essay from Göteborgs universitet/Institutionen för geovetenskaperAbstract : Subduction of hydrated lithospheric mantle is the most important process regarding the transfer of significant amounts of water to depths exceeding 350 km. Hence, the interplay of the thermal structure within the subducted slab together with the PT-stability fields of hydrous ultra-high pressure phases control the dehydration of the slab and the amount of water transported into the deeper mantle.

4. The disclosure of Otto Meyer's secret : An evaluation of composition and casting properties of the Fritzi alloy
University essay from KTH/MaterialvetenskapAbstract : The increased copper price during the first world war forced the Swedish master founder OttoMeyer to invent a new alloy in order to continue casting artworks at a reasonable cost. The recipe of the alloy was a secret that Meyer kept to himself even unto death. READ MORE

5. Secondary Steel Metallurgy Slag Design and MgO-C Refractory Implications : Theoretical and Practical Considerations
University essay from Luleå tekniska universitet/Industriell miljö- och processteknikAbstract : MgO-C based refractory materials, often used in secondary steel making, are exposed to variouswear mechanisms in its application. The wear could be divided into oxidative, chemical andabrasive categories, all behaving differently and all being influenced by different factors. READ MORE
