  1. 21. Renewables Based Polygeneration for Rural Development in Bangladesh

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :MD. Ershad Ullah Khan; KTH.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digester; solar PV; polygeneration; cooking gas; gas engine; electricity; membrane distillation; arsenic safe water; Anaerobisk rötkammare; solceller; polygenerering; matlagningsgas; gasmotor; elektricitet; membrandestillering; arsenikfritt vatten; Energiteknik; Energy Technology;

    Sammanfattning : Despite the country's rural electrification programme, kerosene is the predominant source for lighting, and unsustainable and polluting woody biomass is virtually the only option available for cooking. The rural population also struggles with unsafe drinking water in terms of widespread arsenic contamination of well water. LÄS MER

  3. 23. Catalytic Combustion in Gas Turbines Experimental Study on Gasified Biomass Utilization

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Arturo Manrique Carrera; KTH.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Technology;

    Sammanfattning : 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.
