  1. 21. Kontinuerlig rötning med hydrokol för högre biogasutbyte

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Annette Kariis; [2023]
    Nyckelord :Biogas; Continuous anaerobic digestion; Hydrochar; Hydrothermal Carbonisation; Life-cycle costing; Biogas; kontinuerlig anaerob rötning; Hydrokol; Hydrotermisk karbonisering; Livscykelkostnad;

    Sammanfattning : Befolkningsökningen och därmed efterfrågan på energikällor som tillhandahålls från fossila bränslen leder till allvarliga miljöproblem på grund av utsläpp av växthusgaser. En annan utmaning är att effektivt hantera organisk avfall som till exempel matavfall som genereras världen över. LÄS MER

  3. 22. Flexible Sector Coupling (FSC) of Electrical and Thermal Sectors via Thermal Energy Storage (TES) : A Case Study on Oskarshamn Energi

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Raúl Calvo García; Jose María Marín Arcos; [2023]
    Nyckelord :Flexible sector coupling FSC ; district heating DH ; thermal energy storage TES ; heat pump HP ; capacity optimization; dispatch optimization; open-access tools; Flexibel sektorkoppling; fjärrvärme; termisk energilagring; värmepump; kapacitetsoptimering; leveransoptimering; verktyg med öppen tillgång;

    Sammanfattning : The integration of distributed energy sources and systems is of high relevance for the transition towards a more sustainable energy system. Taking into consideration the  amount of emissions produced by the heating sector, which account for at least half of the energy demand in buildings, district heating systems have the potential to play a key role in the transition, by enabling the integration of various energy sources and provide flexible energy services to the grid.

  4. 23. Leveraging green hydrogen to decarbonise the aviation industry : A case study on electrofuels in Sweden

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Jakob Bergene; Jonathan Bruchhausen; [2023]
    Nyckelord :Electrofuel; e-fuel; electrokerosene; e-kerosene; SAF; sustainable aviation fuel; sustainable aviation; complementarity formation mechanisms; technology value chains; TVC; Techno-economic analysis; TEA; Elektrobränsle; e-bränsle; elektrofotogen; e-fotogen; SAF; sustainable aviation fuel; sustainable aviation; komplementära formationsmekanismer; technology value chains; TVC; Techno-economic analysis; TEA;

    Sammanfattning : For the EU to reach its 2050 climate targets the aviation industry that is highly dependent on fossil fuels needs to drastically reduce its emissions. In the decarbonisation of the aviation industry drop-in sustainable aviation fuels (SAFs) have been identified as a promising solution to abate the industry’s emissions. LÄS MER

  5. 24. Biokonvertering av Brödavfall till Svampfilmer för Textila Applikationer

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Samira Syed; [2023]
    Nyckelord :Filamentous Fungi; Aspergillus oryzae; Food Waste; Bread Waste; Wet-laid; Casted; Tara; Myrobalan; Quebracho; Chestnut; Tannin;

    Sammanfattning : Bread waste represents a significant portion of global food waste, necessitating innovative approaches for its valorization. This research project explores the utilization of bread waste through fermentation with Aspergillus oryzae to produce fungal film which could be used for textile applications. LÄS MER

  7. 25. Nodulation and biomass development of yellow and blue lucerne under pH stress

    Master-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :Katarina Boström; [2023]
    Nyckelord :lucerne; blue lucerne BL ; yellow lucerne YL ; E. meliloti; nodulation; pH;

    Sammanfattning : Approximately 77% of global arable land use is devoted to forage cultivation, which is the basis for animal production and global food security. Therefore a sustainable and biologically diverse forage cultivation is needed. Feed for cattle needs to contain a good balance between fibre, energy and protein. LÄS MER
