  1. 1. Power to gas Bridging renewable electricity to the transport sector

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Farzad Mohseni; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transport; renewable electricity; synthetic fuels; energy; power to gas;

    Abstract : Globally, transport accounts for a significant part of the total energy utilization and is heavily dominated by fossil fuels. The main challenge is how the greenhouse gas emissions in road transport can be addressed. Moreover, the use of fossil fuels in road transport makes most countries or regions dependent on those with oil and/or gas assets. READ MORE

  2. 2. Biofuels from Kraft Black Liquor : Pilot-Scale Gasification Development and Techno-Economic Evaluation of Industrially Relevant Biofuel Production Pathways

    University dissertation from Luleå University of Technology

    Author : Yawer Jafri; Luleå tekniska universitet.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofuels; black liquor; pyrolysis oil; gasification; drop-in; energy systems; techno-economic; Energiteknik; Energy Engineering;

    Abstract : Fuel combustion for transport was responsible for 24% of EU-28 greenhouse gas (GHG) emissions in 2016. Member states are expected to ensure that the share of renewable energy in the transport sector is at least 14% by 2030. Some countries, such as Sweden, have more ambitious targets. READ MORE

  4. 4. Humidification Processes in Gas Turbine Cycles

    University dissertation from Division of Thermal Power Engineering Department of Energy Sciences Faculty of Engineering Lund University

    Author : Marcus Thern; Lunds universitet.; Lund University.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; applied thermodynamics; Thermal engineering; Energiforskning; Energy research; HAT; Biomass; Biofuel; Humidification; Evaporation; Evaporative gas turbine ; Humid air turbine ; Termisk teknik; termodynamik;

    Abstract : The global climate change caused by emissions of greenhouse gases from combustion processes has been recognized as a continuously growing problem and much research focuses on improving the environmental performance of gas turbines. The potential of improving gas turbine component efficiencies has become smaller each decade and therefore, thermodynamic cycles have become more interesting for power producing units. READ MORE

  5. 5. Process Integration Opportunities for Synthetic Natural Gas (SNG) Production by Thermal Gasification of Biomass

    University dissertation from Division of Thermal Power Engineering Department of Energy Sciences Faculty of Engineering Lund University
