  2. 1. Methods to quantify and qualify truck driver performance

    Author : Iulian Carpatorea; Slawomir Nowaczyk; Thorsteinn Rögnvaldsson; Wahde Mattias; Högskolan i Halmstad; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Driver performance; heavy-duty vehicle; fuel economy; fuel consumption; fuel prediction; truck driver;

    Abstract : Fuel consumption is a major economical component of vehicles, particularly for heavy-duty vehicles. It is dependent on many factors, such as driver and environment, and control over some factors is present, e.g. route, and we can try to optimize others, e. READ MORE

  4. 2. Fuel-efficient driving strategies

    Author : Sina Torabi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speed profile optimization; fuel efficiency; neural networks.; energy efficiency; genetic algorithms; performance analysis; road grade estimation; mass estimation; vehicle platooning;

    Abstract : This thesis is concerned with fuel-efficient driving strategies for vehicles driving on roads with varying topography, as well as estimation of road grade and vehicle mass for vehicles utilizing such strategies. A framework referred to as speed profile optimization (SPO), is introduced for reducing the fuel or energy consumption of single vehicles (equipped with either combustion or electric engines) and platoons of several vehicles.

  5. 3. Molten carbonate fuel cells for electrolysis

    Author : Lan Hu; Carina Lagergren; Göran Lindbergh; Søren Højgaard Jensen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Durability; electrode kinetics; gas phase mass transport; molten carbonate electrolysis cell; molten carbonate fuel cell; performance; reversible.; Chemical Engineering; Kemiteknik;

    Abstract : The molten carbonate fuel cell has evolved to current megawatt-scale commercial power plants. When using the fuel cell for electrolysis, it provides a promising option for producing fuel gases such as hydrogen and syngas. The cell can thereby operate reversibly as a dual energy converter for electricity generation and fuel gas production. READ MORE

  6. 4. Fuel Cells and Biogas

    Author : Lars Hedström; Per Alvfors; Peter Lund; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air bleed; biogas; carbon dioxide; carbon monoxide; current distribution; dilution; efficiency; energy conversion; energy systems; experimental; fuel cell; fuel cell systems; PEFC; poisoning; reformate; SOFC; Chemical energy engineering; Kemisk energiteknik;

    Abstract : This thesis concerns biogas-operated fuel cells. Fuel cell technology may contribute to more efficient energy use, reduce emissions and also perhaps revolutionize current energy systems. The technology is, however, still immature and has not yet been implemented as dominant in any application or niche market. READ MORE
