  1. 1. Exploiting cross-level linkages to steer the bioenergy transition

    Författare :Francis X Johnson; Semida Silveira; Geert Verbong; KTH; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; energy transition; modern bioenergy; traditional biomass; cross-level linkages; institutional design; regional development; alternative fuels; Energy Technology; Energiteknik;

    Sammanfattning : This thesis develops the notion of the bioenergy transition as the long-term transformation of biomass from a local resource into a global commodity. An historical assessment is combined with interdisciplinary analysis that focuses especially on liquid biofuels and highlights the environmentally innovative case of bioethanol. LÄS MER

    Författare :Dilip Khatiwada; Semida Silveira; Faaij André; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioenergy and biofuel; bioethanol industry; development trend; sustainability assessment; climate change mitigation; energy security; life cycle assessment; systems optimisation; bioenergi och biobränsle; bioetanolindustri; utvecklingstrender; hållbarhetsbedömning; motverka klimatförändringar; energisäkerhet; livscykelanalys; systemoptimering; SRA - Energy; SRA - Energi;

    Sammanfattning : The continuous depletion of fossil fuel reserves, the global agenda on climate change and threats to energy security have led to increased global interest in the exploration, production and utilisation of bioenergy and biofuels. Access to modern bioenergy carriers derived from the efficient conversion of locally available biomass resources is indispensable for economic growth, rural development and sustainable development in developing countries.

    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Biomass gasification; second-generation biofuels; global CO2 emissions; energy system optimisation;

    Sammanfattning : Bioenergy will play an important role in reaching the EU targets for renewable energy. Sweden, with abundant forest resources and a well-established forest industry, has a key position regarding modern biomass use. LÄS MER

  4. 4. The dielectric properties of solid biofuels

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

    Sammanfattning : 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. LÄS MER

  5. 5. Characteristic Properties and Applications of Fine Particles in Biomass Gasification

    Författare :Azhar Malik; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gasification; Biomass; Fine particles; catalyst deactivation; dilution probe sampling; organic;

    Sammanfattning : The gasification of biomass is a promising route to increase the share of renewable sources in the energy mix. Besides having an overall higher thermal efficiency than combustion, it also offers the possibility of producing gaseous and liquid biofuels that can be used in the transport sector. LÄS MER
