  1. 1. Modelling the chemical recycling of plastic waste via pyrolysis and analysing integration with existing refinery infrastructure

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Simon Dahl; [2023]
    Keywords : Pyrolysis; Recycling; Integration; Modelling; Simulation; Techno-economic; Plastic; Chemical engineering; Technology and Engineering;

    Abstract : Current plastic management is unsustainable as large amounts of plastic end up landfilled or in the ocean, necessitating an expansion of waste management infrastructure. Pyrolysis is a viable chemical recycling option, and in this report a pyrolysis model is constructed in Aspen Plus. READ MORE

  3. 2. Comparative Analysis of On-site vs Off-site green-Hydrogen Value Chain Scenarios to cover projected Aviation demand : A case for Toulouse Blagnac Airport in France

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Stathis Alexandrou; [2023]
    Keywords : Hydrogen Production; Value Chain Analysis; Levelized Cost of Hydrogen Production LCOH ; Hydrogen for Aviation; France; Toulouse Airport; Analys av vätgasens värdekedja; kostnader för vätgasens försörjningskedja; LCOH; flytande vätgas; vätgas för luftfarten; Frankrike; Toulouse Airport; ;

    Abstract : Amidst the efforts to mitigate the energy-related carbon emissions of human activities and pursuing a net-zero future by 2050, the aviation sector, as part of a wider group of hard-to-decarbonize sectors is responsible for 12% of all the transportation emissions globally. Green Hydrogen as a zero-emissions alternative fuel from water and renewable energy serves as a prime candidate to replace conventional aviation fuels and lead the way towards carbon-free flights.

  4. 3. Green hydrogen production in SE4, a business case for large-scale green hydrogen in SE4

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Petter Håkansson; [2023]
    Keywords : Technology and Engineering;

    Abstract : As the greenhouse gas emissions keep on increasing the need for solutions to help reduce emissions across all sectors has never been greater. The European Union has pointed out green hydrogen as a step in increasing the sustainability of the energy sector in Europe. READ MORE

  5. 4. Flashlamp Annealing for Improved Ferroelectric Junctions

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Theodor Blom; [2023]
    Keywords : Flashlamp annealing; ferroelectricity; hafnia oxide; III-V semiconductor; thermal annealing; device performance; Technology and Engineering;

    Abstract : The effects of flashlamp annealing (FLA) on the quality of ferroelectric HfxZr1–xO2 (HZO) interfaces, integrated on InAs substrates, are evaluated. For the integration of ferroelectric HZO on III-V semiconductors the crystallization via rapid thermal processing (RTP) can severely degrade the HZO/III-V interface. READ MORE

  6. 5. Energy Neutral User Equipment : powering cellular IoT applications using energy harvesting

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Tomas Lorenzo Henriques Vazquez; [2022]
    Keywords : Energy harvesting; Vibration energy harvesting; Energy neutral; Internet of Things; Autonomous systems; Power management; Low Power Wide Area Networks; LTE-M; NB-IoT; Energiskördning; Vibrationsenergiskörd; Energineutral; Sakernas internet; Autonoma system; Energihantering; Lågenerginätverk med lång räckvidd; LTE-M; NB-IoT;

    Abstract : With the rise in the number of Internet of Things (IoT) applications, there is also an increase in the number of batteries being used to power these connected devices. The lifespan of IoT devices is usually limited by how long their batteries last. READ MORE
