  2. 11. Power Grid Resilience to High Impact Low Probability Events

    Author : Samuel Forsberg; Mikael Bergkvist; Karin Thomas; Lars Nordström; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Extreme weather; HILP events; offshore wind; power grid; resilience; vulnerability; Electrical Engineering with specialization in Systems Analysis; Elektroteknik med inriktning mot systemanalys;

    Abstract : The electrification of societies and the decarbonisation of electricity production are changing energy systems worldwide. A fast transition towards the replacement of fossil fuels by intermittent renewable energy sources is expected in the next decades to combat climate change. READ MORE

  4. 12. Process integration to increase woody biomass utilization for energy purposes

    Author : Sennai Mesfun; Francesco Fantozzi; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Woody biomass is an abundant renewable energy resource in Sweden, and the Swedish government has been promoting research and development programs for the exploitation of this resource as a mean to meet the targets on the reduction of the carbon dioxide emissions from the industrial, energy and transportation sectors. This thesis aims at expanding the knowledge on the efficient utilization of the available woody biomass, so that a larger amount of this renewable resource can be used for energy purposes. READ MORE

  5. 13. Capacitive Mixing for Extracting Concentration Gradient Energy

    Author : Zhi Zou; Longcheng Liu; Chia-Hung Hou; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capacitive mixing; salinity gradient energy; salt difference energy; electric double layer; flow electrode CapMix; kapacitiv blandning; salthaltsgradientenergi; saltskillnadsenergi; elektriskt dubbelskikt; flödeselektrod CapMix.; Chemical Engineering; Kemiteknik;

    Abstract : Capacitive mixing (CapMix) is a renewable method of extracting energy from the salinity gradient energy (SGE) between seawater and freshwater. The classical CapMix systems using solid electrodes generate electricity by periodically circulating seawater and freshwater into the CapMix system. READ MORE

  6. 14. Catalytic Combustion in Gas Turbines : Experimental Study on Gasified Biomass Utilization

    Author : Arturo Manrique Carrera; Torsten H. Fransson; Gianpiero Groppi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Technology;

    Abstract : Environmental and geopolitical concerns encourage societies towards the utilization of renewable energy sources (RES). Photovoltaic and wind power can produce electricity directly, although their intermittent characteristic negatively affects the security and safety of the energy supply chain; moreover, in order to be viable it is necessary to establish energy storage systems and to find mechanisms to adapt the power distribution grid to larger production variability.

  7. 15. An experimental investigation of flow in a Kaplan runner : steady-state and transient

    Author : Kaveh Amiri; Bjarne Børresen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Water turbines are since some years widely used for grid stabilization purposes according to their exceptional load variation capability which gives them the ability to compensate grid fluctuations initiated by the customer’s consumption or intermittent electricity production systems such as wind and solar power. Different renewable power generation technologies can be combined in mini-grids to electrify isolated villages and extend existing grid networks. READ MORE
