  1. 16. Weight Optimization of Vertical-Axis Wind Turbine Blades constructed in Swedish Fossil Free Steel : With respect to fatigue life time

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Johannes Hall; Albin Larsson; [2023]
    Keywords : VAWT; Wind Turbine Blade; SSAB; Fossil-Free; Weight Optimization; Topology Optimization; Sizing Optimization; NACA 0018; STRENX 1300; Abaqus; Tosca Structure; VAWT; Vindturbinblad; SSAB; Fossilfritt; Viktoptimering; Topologioptimering; Size-Optimering; NACA 0018; STRENX 1300; Abaqus; Tosca Structure;

    Abstract : Wind turbines have been utilized for centuries to harness energy from the wind. Commercial wind turbine blades are typically made from composite materials, which are difficult to recycle, leading to blades ending up in landfills at the end of their lifecycle. Additionally, these materials contribute to microplastic pollution. READ MORE

  3. 17. Enabling a sustainable transition of a waterborne transport system : By identifying essential aspects and actors

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

    Author : Julia Apelgren; Sara Kronvall; [2023]
    Keywords : Sustainable transition; Waterborne transport system; Transport system; Public transport system; Fossil free fuels; System theory; Passenger ferry; Commuter ferry; Electric ferry; Hållbar omställning; Vattenburet transport system; Transport system; Kollektivtrafik; Fossila bränslen; Systemteori; Passagerarfärja; Pendelbåt; Elektrisk färja;

    Abstract : In light of the emerging consequences of climate change, there is a need for a sustainable transition of the marine sector, including waterborne transport systems, towards implementation of fossil free fuels and technologies. The thesis limits its scope to solely include passenger ferries that are suitable for calm waters and often operates on shorter distances, which are often incorporated in a public transport system and/or archipelago traffic.

Therefore, the company LKAB is working to make the production process of iron ore pellets fossil-free. In particular, this thesis project focuses on the pellet induration stage and addresses the mathematical optimization of the process. READ MORE

  6. 20. Klimateffekterna av elektrobränsle för flyg

    University essay from SLU/Dept. of Energy and Technology

    Author : Jonatan Persson; [2023]
    Keywords : Livscykelanalys LCA ; växthusgaser; klimatförändringar; Carbon Capture and Utilization CCU ; flygindustrin; utsläppsminskningar; HySkies;

    Abstract : Kan elektrobränsle vara den nyckeln som flygindustrin behöver för att bekämpa klimatförändringarna? Detta arbete handlar om att utföra en livscykelanalys av elektrobränsle för att bedöma dess effektivitet som en hållbar lösning för att minska klimatpåverkan från flygindustrin. Elektrobränsle är en variant av hållbart flygbränsle, SAF (Sustainable Aviation Fuel). READ MORE
