  1. 21. Greenhouse Gas Emissions Reduction in the Heavy-Duty Transport Sector - A Case Study of Renewable Energy Carriers in Sweden

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Karolina André; William Degerstedt; [2021]
    Keywords : Battery electric vehicle; Biofuels; Greenhouse gas; Heavy-duty vehicles; LCA; Renewable energy carriers; Renewable fuels; TCO; Transport sector; Well-to-wheel; Technology and Engineering;

    Abstract : Den svenska transportsektorn står för ungefär en tredjedel av landets totala utsläpp av växthusgaser och släppte 2019 ut 16,4 Mt CO2-ekvivalenter. Av dessa står den tunga vägtrafiken för cirka 20 % och är efter passagerarfordonen den största källan till utsläpp av växthusgaser inom sektorn. READ MORE

  3. 22. Stability testing of all-trans-retinol in an experimental cosmetic formulation and in methanol and methanol containing butylhydroxytoluene (BHT) using reversed-phase HPLC

    University essay from KTH/Kemi
