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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Arturo Manrique Carrera; KTH.; [2014]
    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.

    Abstract : Solid oxide fuel cells (SOFCs), working at high temperatures with an incomplete fuel oxidation process, have become an interesting candidate for combination with conventional power generation technology, such as gas turbines, in order to develop power plants that are both functional and efficient. An absolute condition for successful analysis and optimisation of such plants is the existence of reliable simulation tools. READ MORE

  4. 4. Bimetallic Palladium Catalysts for Methane Combustion in Gas Turbines

    University dissertation from Stockholm : KTH

    Author : Katarina Persson; KTH.; [2006]
