  1. 21. 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

  3. 22. Evaluation of long-term effects of excavated sulfide-bearing rock : - A case study in western Sweden

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

    Author : Ida Sundblom; [2022]
    Keywords : sulfide-bearing rock; acid rock drainage; sulfide oxidation;

    Abstract : Sulfide-bearing rock that is excavated in conjunction with construction projects can cause environmental and construction engineering problems. Sulfidic minerals oxidize when they are exposed to an oxidant and water, which can make them generate acid rock drainage (ARD) with high concentrations of metals and sulphate. READ MORE

  4. 23. Combining Smart Energy Storage with a Nordic PV Park : An explorative study of revenue-improving and cost-reducing battery services

    University essay from Uppsala universitet/Byggteknik och byggd miljö

    Author : Amanda Bränström; Jonna Söderberg; [2021]
    Keywords : battery storage; energy storage; PV park; primary frequency regulation; energy arbitrage; NPV; VRE; Li-ion; service stacking;

    Abstract : With global climate change as the main driver, there is an increase towards including more variable renewable energy (VRE) sources in the electricity mix. Energy production from utilizing the photovoltaic effect, or PV power, is increasing rapidly and is visioned to cover 5 – 10 % of Sweden’s electricity demand in 2040. READ MORE

  5. 24. Hydrogen Production and Storage Optimization based on Technical and Financial Conditions : A study of hydrogen strategies focusing on demand and integration of wind power.

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Hanna Langels; Oskar Syrjä; [2021]

    Abstract : There has recently been an increased interest in hydrogen, both as a solution for seasonal energy storage but also for implementations in various industries and as fuel for vehicles. The transition to a society less dependent on fossil fuels highlights the need for new solutions where hydrogen is predicted to play a key role. READ MORE

  6. 25. Performance Evaluation of a Photovoltaic/Thermal (PVT) Collector with Numerical Modelling

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

    Author : Mila Ebrahim; [2021]
    Keywords : Solar energy; Renewable energy; Photovoltaic thermal collector; PV Thermal; PVT Collector; Performance; Numerical modelling; COMSOL Multiphysics; Ground Source Heat Pump; Solenergi; Förnybar energi; kominerad solcell solfångare; PVT panel; Prestanda; Numerisk modellering; COMSOL Multiphysics; Bergvärme;

    Abstract : In Photovoltaic/Thermal (PVT) technology, both PV and solar thermal technology are integrated in the same module for simultaneous electricity and heat production. Research has shown that there are multiple benefits from integrating PVT collectors with a ground source heat pump (GSHP) system, since it allows for seasonal storage of thermal energy over the year.
