  1. 26. Manufacturing batteries of the future : Critical challenges and undertakings to create the next generation energy storage

    Kandidat-uppsats, KTH/Produktionsutveckling

    Författare :Victor Carlsson; Victor Granat; [2023]
    Nyckelord :;

    Sammanfattning : In today's world, a dominating piece of news is the global race for large-scale production of Lithium-ion batteries (LIB). LIBs are important because they have become the most widely used type of rechargeable battery in modern electronic devices, such as smartphones, laptops, energy storage systems, and electric vehicles.

  3. 27. Analysis of performance data of wind turbines for polar regions

    L3-uppsats, Uppsala universitet/Högenergifysik

    Författare :Arnau Serra Garet; [2023]
    Nyckelord :;

    Sammanfattning : The Radio Neutrino Observatory in Greenland is situated at Summit Station. Due to its isolatedlocation the main power to support the autonomous radio stations is solar energy. However,during the winter months when there is no sun another strategy needs to be found. LÄS MER

  4. 28. Evaluation of probabilistic forecasts in Uppsala and its potential use in winter road maintenance

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Elisabet Johansson; [2023]
    Nyckelord :forecast evaluation; ensemble system; MetCoOp; winter road maintenance; snow removal; utvärdering; ensembelprognos; MetCoOp; snöröjning; vinterväghållning;

    Sammanfattning : Efficient winter road maintenance is crucial for safety and societal function during the winter months in Sweden. This report aims to evaluate the MetCoOp ensemble system CMEPS and investigate its potential use as a basis for formulating criteria for snow removal that accounts for forecasted weather. LÄS MER

  5. 29. Investigation of a balanced Swedish energy system in 2045 : Analysis of technical specifications for flexibility needed in a future Swedish intermittent electricity system.

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Petter Larsson; [2023]
    Nyckelord :Ancillary services; Energy storage; Grid Flexibility; Market analysis; Sustainable electricity production.; Stödtjänster; Energilagring; Flexibilitet; Marknadsanalys; Hållbar elproduktion.;

    Sammanfattning : As part of Sweden's goal of zero carbon dioxide emissions, renewable energy will play an increasingly important role in the future. A major change in the electrification of industries and the transport sector will lead to an ever-increasing need for electricity production. LÄS MER

  7. 30. Fouling modelling in a UHT unit based on plant data.

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Thai Lam; [2023]
    Nyckelord :UHT; dairy; tubular heat exchanger; fouling development; fouling removal; food engineering; Technology and Engineering; Agriculture and Food Sciences;

    Sammanfattning : Heat treatment of dairy products is essential for food safety, one way to perform this is ultra-high temperature (UHT) processing. During the process, macronutrients and minerals form fouling deposits which impairs heat transfer. Eventually the fouling needs to be removed chemically by alkaline and acidic detergents. LÄS MER
