  1. 1. Integrating Waste Heat from Hydrogen Production Into District Heating

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Fawzi Kayali; [2023]
    Keywords : Hydrogen; Electrolysis; Waste Heat Recovery; Combined Heat and Power Plant; District Heating; Simulation; Sustainable Heating Systems; Technology and Engineering;

    Abstract : The aim of this research is to explore the feasibility of the integration of waste heat from electrolyzers within a Combined Heat and Power (CHP) plant and district heating (DH) network and suggest a practical setup for integration. With the escalating emphasis on the development of green hydrogen through electrolysis powered by renewable energy, a substantial amount of waste heat is generated, typically left unused. READ MORE

  3. 2. 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

  4. 3. Parametric investigation of a theoretical organic rankine cycle

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Jim Wernersson; [2023]
    Keywords : ;

    Abstract : The energy resource waste heat or low-grade thermal energy is available in vast quantities. Tapping into this resource and converting it to electrical energy would not only reduce energy waste but also has the potential to eliminate greenhouse gas emissions. READ MORE

  5. 4. Fano Resonances in Time-Dependent Wells

    University essay from Uppsala universitet/Materialteori

    Author : Anton Gregefalk; [2023]
    Keywords : Fano resonance; Floquet scattering; Pumped shot-noise; Linear band tilt; Quadratic band touching; Time periodic Hamiltonian;

    Abstract : Floquet’s theorem, a temporal analogue of Bloch’s theorem, is used for studying a time-dependent potential. With applications in cold atoms on optical lattices, quantum dots and more, there is a growing interest in Floquet engineering exotic materials and phases. READ MORE

  6. 5. Benchmarking a 1 kW hybrid hydrogen fuel cell system

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Jonathan Envall; [2023]
    Keywords : PEMFC; fuel cell; UAV; hybrid; Technology and Engineering;

    Abstract : Unmanned Aerial Vehicles (UAV's) offer great versatility in the tasks that they may perform and they are today used in many sectors. The H24LEO project, administered by the Lund University School of Aviation, aims to develop and demonstrate a hybrid proton-exchange membrane fuel cell-powered UAV to aid in search and rescue operations performed by the Swedish Maritime Administration, and reduce the greenhouse gas emissions compared to similar work performed by helicopters.
