  2. 11. Modelling Freshwater-Seawater Interactions in Coastal Aquifers : Long-term Trends and Temporal Variability Effects

    Author : Carmen Prieto; KTH; []
    Keywords : seawater intrusion; seasonal variability; artificial recharge; spatial and temporal randomness;

    Abstract : Over-exploitation of coastal aquifers causes seawaterintrusion and eventually contamination of groundwater wells inmany parts of the world. Desalination of brackish water andartificial recharge of treated wastewater may then be asustainable strategy for managing groundwater supply inwater-stressed regions. READ MORE

  4. 12. Integration of Membrane Distillation and Solar Thermal Systems for Coproduction of Purified Water and Heat

    Author : Tirumala Uday Kumar Nutakki; Andrew R. Martin; Guillermo Zaragoza; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar Membrane Distillation; polygeneration; TRNSYS; Integrated systems; Energy Technology; Energiteknik;

    Abstract : In the Middle East and North Africa region fresh water resources are very scarce and theexisting sources are depleting rapidly. Desalination is the method to fulfill increasing waterdemand, and people depend mostly upon bottled water for drinking purposes. READ MORE

  5. 13. Studies of a Vertical Axis Turbine for Marine Current Energy Conversion : Electrical system and turbine performance

    Author : Johan Forslund; Karin Thomas; Cameron Johnstone; Uppsala universitet; []
    Keywords : Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Ocean energy is a field of growing interest when it comes to renewable energy thanks to its high density of energy per unit area, and to the high predictability. Conversion of hydrokinetic energy, found in marine currents, is the utilization of the energy in free-flowing water for conversion to electric energy. READ MORE

  6. 14. Thermoelectric polymer-cellulose composite aerogels

    Author : Shaobo Han; Xavier Crispin; Simone Fabiano; Rachel Segalman; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Thermoelectric materials are scrutinized as energy materials and sensing materials. Indeed, they convert thermal energy into electrical energy. In addition, those materials are actively sensitive to a temperature modification through the generation of an electric signal. READ MORE

  7. 15. Control strategies for various grid conditions in wave energy system

    Author : Md Imran Ullah; Irina Temiz; Johan Forslund; Cecilia Boström; Deepak Elamalayil Soman; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The imperative goal of reducing carbon emissions and reaching net zero emissions in electricity generation has driven various renewable technologies, including wind energy, solar energy, and wave energy, among others. Even though wave energy is a recent addition to the already existing renewable energy technologies, it offers distinct advantages, such as a high power density and lower inter-annual variability compared to wind energy.
