  1. 11. Aviation’s future energy requirements

    University essay from Lunds universitet/Trafikflyghögskolan

    Author : Leonard Holmgren Holm; [2021]
    Keywords : Aviation fuels; Sustainable aviation fuels; Hydrogen power; Electric aircraft; Environmental impact; FLYL01; Technology and Engineering;

    Abstract : Flygindustrin närmar sig ett vägval där sektorn kommer behöva bestämma sig för vilken typ av framtida energimöjligheter den ska använda sig av. En väg är att även fortsättningsvis använda sig konventionellt flygbränsle vilket med stor sannolikhet kommer leda till fortsatt ökande utsläpp globalt, och den andra vägen leder sektorn till hållbart flygbränsle, vätgasdrift och batteridrivna elektriska flygplan.

  2. 12. Carbon Abundance in the Milky Way Galaxy

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Calum Kvernes Macpherson; [2021]
    Keywords : Carbon; Abundance; Milky Way; Chemical Evolution; Physics and Astronomy;

    Abstract : Carbon is the fourth most abundant element after hydrogen, helium and oxygen. It is a product of stellar nucleosynthesis as well as it being an important bio signature for life; this makes the analysis of carbon very fundamental. READ MORE

  3. 13. Analysis of trends in policies and pathways for climate neutrality within the steel industry : A case study of powder metal company Höganäs AB

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Anna Westerberg; Emma Mörlin; [2021]
    Keywords : powder metal; climate neutral; decarbonising; steel industry; IPCC;

    Abstract : To be in line with the Paris Agreement and mitigate average temperature rise to 1.5°C, and to a maximum of 2°C, greenhouse gas emissions will have to be reduced close to zero before mid-century. If these targets are to be reached, rapid and complete decarbonisation of every sector within the global economy is required. READ MORE

  4. 14. Development of Novel (Cu,Fe)3O4 Coatings for AISI 441 Solid Oxide Cell Interconnects : Coating optimization and long-term study

    University essay from KTH/Materialvetenskap
