3. 12. Small-Scale Production of Fuel-Cell Hydrogen

   Författare :Christian Hulteberg; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogen; Chemical Engineering; Catalysis; Small-Scale;

   Sammanfattning : The work presented here aims at producing hydrogen for proton-exchange fuel-cell applications from hydrocarbons. This thesis describes an integrated catalytic converter comprising a steam-reforming reactor (heat of reaction supplied by catalytic combustion), a water-gas shift reactor and a preferential oxidation of carbon monoxide reactor, and the work performed on the fuel processing catalysts therein.

4. 13. Climate impact of the sustainable use of forest biomass in energy and material system : a life cycle perspective

   Författare :Sylvia Haus; Johan Bergh; Bishnu Chandra Poudel; Krushna Mahapatra; Göran Berndes; Linnéuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest residues; fossil fuel substitution; forest management; radiative forcing; land use change; climate change; bioenergy; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology; Byggteknik; Civil engineering;

   Sammanfattning : Human society releases greenhouse gas emissions to the atmosphere while providing housing, heat, mobility and industrial production. Man-made greenhouse gas emissions are the main causes of climate change, coming mainly from burning fossil fuels and land-use changes. LÄS MER

5. 14. Two studies on fuel choice in power generation

   Författare :Patrik Söderholm; Luleå tekniska universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

   Sammanfattning : This dissertation consists of two studies, both related to the impacts of economic and political factors on fuel choice in electric power generation. The primary purpose of the first study is to estimate the degree of price-induced interfuel substitution between three fossil fuels in West European power generation. LÄS MER

7. 15. The Rôle of Side-Chains in Polymer Electrolytes for Batteries and Fuel Cells

   Författare :Jaanus Karo; Hans Siegbahn; Daniel Brandell; Patrik Johansson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; molecular dynamics; polymer electrolytes; side-chains; Li-ion batteries; proton exchange membrane fuel cell PEMFC ; PFSA membrane; Other chemistry; Övrig kemi; Atomic and molecular physics; Atom- och molekylfysik; Materialvetenskap; Materials Science;

   Sammanfattning : The subject of this thesis relates to the design of new polymer electrolytes for battery and fuel cell applications. Classical Molecular Dynamics (MD) modelling studies are reported of the nano-structure and the local structure and dynamics for two types of polymer electrolyte host: poly(ethylene oxide) (PEO) for lithium batteries and perfluorosulfonic acid (PFSA) for polymer-based fuel cells.
