    Abstract : Människans påverkan på växthuseffekten har under de senaste åren varit en mycket aktuell fråga. Det är många olika faktorer som bidrar till ett negativt avtryck på miljön, där ett stort bidrag kommer från sektorn bilindustri. Majoriteten av dagens bilar drivs på fossila bränslen som genererar skadande utsläpp på miljön. READ MORE

  2. 2. The Effect of Oil Prices on Patents in Renewable Energy : A DTC Approach

    University essay from KTH/Nationalekonomi

    Author : Mathias Malik Nilsson; [2019]
    Keywords : ;

    Abstract : Although a majority of researchers and policymakers are aware of the need to transition towards renewable energy to tackle climate change, the world is still much dependent on fossil fuels. Using directed technical change (DTC) as a theoretical framework, this thesis aims at understanding how the oil price can direct innovations towards technologies related to renewable energy.

  3. 3. Fast Pyrolysis of Biomass in a Fluidized Bed for Production of Bio-oil and Upgradation by Ex-situ Catalytic Bed

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

    Author : Samina Gulshan; [2019]
    Keywords : ;

    Abstract : Production of bio-oil from biomass is now becoming best substitute of fossil fuels in the transportation sector. Pyrolysis is one of the most promising route to produce bio-oil from biomass.  However, bio-oil needs to be upgraded due to presence of high percentage of oxygenated compounds. READ MORE
