  1. 1. Offshore Marine Substation for Grid-Connection of Wave Power Farms An Experimental Approach

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Rickard Ekström; Uppsala universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave power; Offshore Marine Substation; Grid-Connection; Electrical Systems; Voltage-Source Inverter; On-load Tap Change; Cascaded H-bridge Multilevel Inverter; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Wave power is a renewable energy source with great potential, which is why there are more than a hundred ongoing wave power projects around the world. At the Division of Electricity, Uppsala University, a point-absorber type wave energy converter (WEC) has been proposed and developed. READ MORE

  2. 2. Vertical Axis Wind Turbines Electrical System and Experimental Results

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jon Kjellin; Uppsala universitet.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VAWT; H-rotor; start-up; all-electric control; Power Coefficient; stall; tip speed ratio; Renewable energy; Measurement systems; PM-generator;

    Abstract : The wind power research at the division of Electricity at Uppsala University is aimed towards increased understanding of vertical axis wind turbines. The considered type of wind turbine is an H-rotor with a directly driven synchronous generator operating at variable speed. READ MORE

  3. 3. Thiol−ene Coupling of Renewable Monomers at the forefront of bio-based polymeric materials

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Mauro Claudino; KTH.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thiol-ene chemistry; monounsaturated fatty-acids; renewable resources; cis trans-isomerization; photopolymerization; networks; polyesters; thermal viscoelastic properties; thin-films; unsaturated macro lactones; coatings;

    Abstract : Plant derived oils bear intrinsic double-bond functionality that can be utilized directly for the thiol–ene reaction. Although terminal unsaturations are far more reactive than internal ones, studies on the reversible addition of thiyl radicals to 1,2-disubstituted alkenes show that this is an important reaction.

  4. 4. Low temperature deicing of road infrastructure using renewable energy

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Josef Johnsson; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; borehole thermal energy storage; renewable energy; BTES; numerical simulations; Pavement solar collector; Hydronic heated pavements;

    Abstract : Winter road maintenance is costly but it is inevitable since it is necessary to keep roads accessible and safe during winter. Current winter road maintenance methods use annually 600 000 tons of salt, in the Nordic countries. The salt ends up in the environment along the roads and results in environmental challenges.
