    Abstract : Biomass can be used to substitute the use of fossil fuels in the energy system. Presently, the use of biomass is being promoted in Sweden and the rest of the EU by targets and policies. READ MORE

  5. 8. The dielectric properties of solid biofuels

    Author : Ana Marta Paz; Erik Dahquist; Ebbe Nyfors; Mälardalens högskola; []
    Keywords : dielectric properties; solid biofuels; moisture content determination; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : The use of bioenergy has been increasing due to efforts in fossil fuels replacement. Modern bioenergy technologies aim for high efficiency and low pollution levels, which increases the need for methods for the on-line characterization of biofuels. READ MORE

  6. 9. Adding Fuel to the Fire : North-South dynamics in the geographies of transport energy: the case of EU biofuels

    Author : David Harnesk; LUCSUS; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; energy geography; geopolitics; territorialisation; climate change mitigation; transport; biofuels; agrofuels; European Union EU ; certification; sustainability criteria; sustainability science; energi; geografi; geopolitik; territorialisering; klimatomställning; transport; biodrivmedel; biobränsle; Europeiska Unionen; certifiering; hållbarhetskriterier; hållbarhetsvetenskap;

    Abstract : Since the 2000s, the European Union (EU) has promoted biofuels for transport to achieve climate change mitigation, and rural development in the global South. In contrast, critiques have argued that biofuel promotion impedes more meaningful mitigation while also resulting in dispossession of land and loss of labour opportunities in the global South.
