  2. 1. Towards Sustainable Bioenergy - Governance, Resource potentials and Trade-offs

    Author : Oskar Englund; Evelyne Thiffault; Chalmers tekniska högskola; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; sustainability standards; trade-offs; Bioenergy; biodiversity; governance; biomass potentials; certification;

    Abstract : The global energy system needs to be transformed from fossil dependent to renewable, to cope with the challenges of resource scarcity and climate change. Bioenergy can play an important role in this transformation, but land is scarce, and uncontrolled bioenergy expansion could have unacceptable consequences. READ MORE

  4. 2. Char conversion kinetics and aerosol characterization in biomass gasification

    Author : Leteng Lin; Michael Strand; Alberto Gómez-Barea; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass gasification; fluidized bed; char; kinetics; aerosol; APS; TEOM; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology;

    Abstract : Biomass gasification is a thermochemical conversion by partial oxidation at elevated temperature of solid biomass into a gaseous energy carrier. The product gas contains the major components CO, H2, CO2, CH4, as well as some tar and inorganic impurities and solid particles such as ash, bed material, soot and char. READ MORE

  5. 3. Advancing Bioenergy in Europe: Exploring bioenergy systems and socio-political issues

    Author : Kes McCormick; Internationella miljöinstitutet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Bioenergy; Sustainable Development; Political and administrative sciences; Biomass; Renewable Energy; förvaltningskunskap; Statsvetenskap; Energy Policy; Social sciences; Samhällsvetenskaper;

    Abstract : This thesis concentrates on bioenergy (or biomass utilised for heat, electricity and fuels for transport) as a renewable energy with significant potentials and options. Biomass can be considered as 'stored' solar energy because the process of photosynthesis 'captures' energy from the sun in growing plants. READ MORE

  6. 4. Opportunities for CO2 Reductions and CO2-Lean Energy Systems in Pulp and Paper Mills

    Author : Kenneth Möllersten; KTH; []
    Keywords : CO2 reduction; pulp and paper industry; energy system; biomass; CO2 capture and sequestration; black liquor; gasification; power production; outsourcing; sustainable energy management;

    Abstract : The risk for climate change is a growing concern for theglobal society. According to what is known as the Kyoto Protocol,developed countries have committed themselves to reduce theirgreenhouse gas (GHG) emissions. The purpose of this thesis hasbeen to analyse opportunities for CO2 reductions in Swedish pulpand paper mills. READ MORE

  7. 5. Modelling Climate Policy – Trade-Off Metrics, Resource Markets, and Uncertainty

    Author : Daniel Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; OPEC; GWP; energy; uncertainty; biomass; climate change; oil; land use; greenhouse gases; Kyoto Protocol;

    Abstract : This thesis consists of five papers related to climate change policy. In paper I andpaper II we discuss the use of Global Warming Potentials (GWPs) that facilitate the tradeoffbetween abatement of the different greenhouse gases (GHGs). READ MORE
