  1. 1. Mathematical Modeling and Simulation of Cryogenic Liquid Hydrogen Storage

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Gusten Zandler Andersson; [2023]
    Nyckelord :Modeling; Simulation; Liquid Hydrogen; Storage tank; Modelica; Chemical engineering; Technology and Engineering;

    Sammanfattning : Liquid hydrogen is an attractive alternative to fossil fuels in the aviation industry, but storing it both before and during flights introduces many challenges pertaining to the cryogenic liquid conditions required. Having reliable models to predict the dynamical behavior inside the storage tank is therefore of great interest. LÄS MER

  3. 2. Modeling of a stand-alone liquid air energy storage

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Fabian Andersson; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The aim of this project was to create a model of the stand-alone LAES for use in future work at Siemens Industrial Turbomachinery (SIT). The model was created in IPSEpro with components developed from the software's standard library of power plant components. Required fluid properties were obtained from the Refprop DLL. LÄS MER

  4. 3. Avkokskomprimering till CBG-lager som avkokshantering på LBG-tankstationer

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Energy and Technology

    Författare :Olle Levin; [2019]
    Nyckelord :biogas; förvätskad biogas; komprimerad biogas; LNG; biobränsle; tunga fordon; logistik;

    Sammanfattning : The number of fuel stations for liquefied biogas or liquefied natural gas (LBG or LNG, both composed of liquid methane) in Sweden will increase in the coming few years, from 6 stations to over 30 in total. While there still are very few LNG heavy-duty vehicles (HDV's) on Swedish roads, technical problems may arise at fuel stations due to low consumption. LÄS MER

  5. 4. WELL-TO-WHEELS ANALYSIS OF HEAVY-DUTY TRUCK FUELS : A comparison between LNG, LBG and Diese

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Simon Nylund; Niklas Wenstedt; [2019]
    Nyckelord :Sustainable; energy; GHG; emissions; production; processing; liquefaction; transportation; Hållbar; energi; GHG; utsläpp; produktion; process; förvätskning; transport;

    Sammanfattning : Heavy-duty trucks accounts for 25% CO2 emissions in Sweden and there is approximately 12.6 million heavy-duty vehicles in the EU with different types of fuel and utilization areas. LÄS MER

  7. 5. Auxiliary Heater for Natural Gas Trucks

    Master-uppsats, Linköpings universitet/Maskinkonstruktion

    Författare :Mikael Karlgren Johansson; Kevin Leong; [2017]
    Nyckelord :auxiliary heater; natural gas; biogas; LNG; CNG; LBG; CBG; truck; thermal comfort; heating; BOG; boil-off gas; boil off gas; water to air; WTA; ATA; air to air; water-to-air; air-to-air; climate system; HVAC; fuel system; water system; cooling system;

    Sammanfattning : As alternative fuels are becoming more common, technologies need to adjust to them. Natural gas is one of the alternative fuels that has grown during the latest years in the transport sector. Natural gas consists of around 97 % methane and is the cleanest fossil fuel. LÄS MER
