  1. 1. Decarbonisation of service vessels in offshore wind power through power-to-X self-sufficiency

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

    Författare :Clemens Kellander; Ludvig Fredriksson; [2023]
    Nyckelord :Alternative fuels; compressed hydrogen; battery; production; energy storage; operation and maintenance; O M; offshore; wind power; service vessel; crew transfer vessel; CTV; service operations vessel; SOV; decarbonisation; global warming potential; life cycle; Technology and Engineering;

    Sammanfattning : This report examines the possibilities of decarbonising operation & maintenance vessels for a prospective floating offshore wind power park at the Utsira Nord site in Norway, through self-sufficient energy carrier production utilizing power-to-X-solutions. Possible alternative fuels are identified as compressed hydrogen, batteries, liquid hydrogen, ammonia, methanol, and biofuels, out of which the former two are the subject for thorough investigation in this report.

  3. 2. MPC based Caster Wheel Aware Motion Planning for Differential Drive Robots

    Master-uppsats, KTH/Mekatronik

    Författare :Jon Arrizabalaga Aguirregomezcorta; [2020]
    Nyckelord :Mobile robots; differential drive; caster wheels; motion planning; MPC; Mobila robotar; differentiell drivning; hjul; rörelseplanering; MPC;

    Sammanfattning : The inherited rotation in a caster wheel allows movement in any direction, but pays at the expense of reaction torques. When implemented in a mobile robot, these forces have a negative impact in its performance. One approach is to restrict rotations on the spot by attaching a filter to the output of the motion planner. LÄS MER

  4. 3. Alternative Drivetrain for Future Freight Trucks

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Athanasios Tsamos; [2020]
    Nyckelord :future freight trucks; transportation; sustainable fuels; alternative fuels; future mobility; long distance trucks; hybrid mobility; alternative drivetrain; electric trucks;

    Sammanfattning : Presently, heavy-duty trucks are responsible for approximately 25% of global CO2 emissions. Although the world seems to incline towards the transport sector's electrification, the electrification of long-range freight trucks is profoundly challenging. LÄS MER

  5. 4. Behind the wheel : A closer look at influential relationships among internal factors driving a technological paradigm shift

    Master-uppsats, Uppsala universitet/Industriell teknik

    Författare :Carl-Oscar Helleblad Nymo; [2019]
    Nyckelord :technological paradigm shift; electrification; EV; powertrain; drivetrain; electrified; production; trucks; Scania; organizational change; electric vehicle; automotive;

    Sammanfattning : Global sustainability awareness and governmental regulations are pushing the automotive industry into finding alternatives to carbon dioxide emitting products. Solutions utilizing electricity in the vehicle powertrain is overtaking market share from internal combustion engines (ICE). LÄS MER

  7. 5. Weda pool cleaner Concept P100

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Hared Abukar; Firas Al Saati; [2016]
    Nyckelord :;

    Sammanfattning : Syftet med detta examensarbete var att ta fram en ny drivlina för Wedas nuvarande robot poolrengörare W50. I nuläget är pumpen integrerad i drivlinan som består endast av en motor som driver både hjul och pump. Detta orsakar ett kritiskt problem som påverkar städning vid lutningar i poolen då roboten glider ner för lutningen. LÄS MER
