  1. 1. Fuel Cells and Biogas

    University dissertation from Stockholm : KTH

    Author : Lars Hedström; KTH.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air bleed; biogas; carbon dioxide; carbon monoxide; current distribution; dilution; efficiency; energy conversion; energy systems; experimental; fuel cell; fuel cell systems; PEFC; poisoning; reformate; SOFC; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Chemical energy engineering; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik Kemisk energiteknik;

    Abstract : This thesis concerns biogas-operated fuel cells. Fuel cell technology may contribute to more efficient energy use, reduce emissions and also perhaps revolutionize current energy systems. The technology is, however, still immature and has not yet been implemented as dominant in any application or niche market. READ MORE

  2. 2. Biomass Potential for Heat, Electricity and Vehicle Fuel in Sweden

    University dissertation from Uppsala : Sveriges Lantbruksuniversitet

    Author : Peter Hagström; [2006]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; bioenergy potential; biomass potential; cost analysis; emergy; energy analysis; energy scenarios; systems analysis; thermochemical conversion; SRA - Energy; SRA - Energi;

    Abstract : The main objective of this thesis was to determine how far a biomass quantity, equal to the potential produced within the Swedish borders, could cover the present energy needs inSwedenwith respect to economic and ecological circumstances. Three scenarios were studied where the available biomass was converted to heat, electricity and vehicle fuel. READ MORE

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Engineering mechanics Mechanical and thermal engineering Thermal energy engineering; TEKNIKVETENSKAP Teknisk mekanik Mekanisk och termisk energiteknik Termisk energiteknik; Pellets; stove; boiler; solar heating; DHW preparation; system design; single-family house; electricity savings; Pellet; pelleteldning; kamin; panna; solvärmesystem; varmvattenberedning; systemutformning; småhus; elbesparing; verkningsgrad; emissioner; rökgasförluster; skorstensförlust; diskmaskin; tvättmaskin;

    Abstract : In Sweden, there are about 0.5 million single-family houses that are heated by electricity alone, and rising electricity costs force the conversion to other heating sources such as heat pumps and wood pellet heating systems. Pellet heating systems for single-family houses are currently a strongly growing market. READ MORE
