  1. 1. Hydrogen liquefaction chain: co-product hydrogen and upstream study

    Master-uppsats, KTH/Kemiteknik

    Författare :Salomé Lusson; [2021]
    Nyckelord :hydrogen liquefaction; buffer system; co-product hydrogen; techno-economics; process modelling and simulation; Vätskeformning; buffertsystem; samproduktväte; teknikekonomi; processmodellering och simulering;

    Sammanfattning : The European Green Deal declared that Europe must decarbonize to become carbon-neutral within 2050. To do so, the European Parliament emphasized hydrogen as a major tool for energy transition. In regard of current environmental challenges, liquid hydrogen has raised interest as energy carrier for energy storage and transport. LÄS MER

  3. 2. Hybrid Vehicle Control Benchmark

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Ruchit Anilbhai Bhikadiya; [2020]
    Nyckelord :Hybrid electric vehicle; Dynamic Programming; Powertrain Modes;

    Sammanfattning : The new emission regulations for new trucks was made to decrease the CO2 emissions by 30% from 2020 to 2030. One of the solutions is hybridizing the truck powertrain with 48V or 600V that can recover brake energy with electrical machines and batteries. The control of this hybrid powertrain is key to increase fuel efficiency. LÄS MER

  4. 3. Analysis of the energy consumption of the powertrain and the auxiliary systems for battery-electric trucks

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Guanqiao Song; [2020]
    Nyckelord :Battery-electric truck; Energy consumption analysis; Battery loss; PT1 battery model; Power Take Off; Sankey diagram; Direct-Current charging; Batterielektrisk lastbil; Energiförbrukningsanalys; Batteriförlust; PT1 batterimodell; Power Take Off; Sankey diagram; Direct-Current charging;

    Sammanfattning : The electrification of the truck is crucial to meet the strategic vision of the European Union (EU) to contribute to net-zero greenhouse gas emissions for all sectors of the economy and society. The battery-electric truck is very efficient to reduce the emissions and has also a lower Total Cost of Ownership (TCO) compared to diesel trucks. LÄS MER

  5. 4. Control of a Hydraulic Hybrid System for Wheel Loaders

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Christopher Reichenwallner; Daniel Wasborg; [2019]
    Nyckelord :EMS; Energy management strategy; Rule-based; Hydraulic hybrid; Wheel loader; Construction machinery; SLC; Short loading cycle; Torque converter; Energy recuperation; Energy efficiency; Backward simulation;

    Sammanfattning : In recent years many companies have investigated the use of hybrid technology due to the potential of increasing the driveline’s efficiency and thus reducing fuel consumption. Previous studies show that hydraulic hybrid technology can be favourable to use in construction machinery such as wheel loaders, which often operate in repetitive drive cycles and have high transient power demands.
