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

    Author : Peter Hagström; Bengt Hillring; Per Olov Nilsson; Leif Gustafsson; Paul Mitchell; Skogsmästarskolan Sveriges lantbruksuniversitet; []
    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

  4. 2. Revealing the potential of Nordic microalgae : turning waste streams into resources

    Author : Martin Plöhn; Christiane Funk; Leif J. Jönsson; Maria Barbosa; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microalgae; Biotechnology; bioremediation; Heavy metal; Biopolymer; Biodegradable; Sustainability; Chlorella vulgaris; Biochemistry; biokemi; environmental science; miljövetenskap;

    Abstract : As the world's population grows, the demand for fresh water, food, fuel, energy and modern technology increases tremendously. Not only does this require enormous amounts of resources but it also increases the amount of waste and especially wastewater. READ MORE

  5. 3. High temperature corrosion in biomass-fired energy applications : Alloying effects and test environment comparisons

    Author : Ragna Elger; Rachel Pettersson; Inger Odnevall Wallinder; Rikard Norling; Gordon Tatlock; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; High temperature corrosion; biomass; waste; superheater corrosion; austenitic steel; biomass gasification; alumina-forming austenitic stainless steel; thermodynamic modelling; kinetic modelling; Kemi; Chemistry;

    Abstract : To reduce the greenhouse effect, the use of renewable fuel has to be increased. As renewable fuel has different characteristics compared to fossil fuel regarding content of trace metals, alkali, chlorine and sulphur, the corrosion characteristics in high temperature energy processes have to be evaluated.

  6. 4. Thermochemical behavior of pretreated biomass

    Author : Amit Kumar Biswas; Weihong Yang; Wlodzimierz Blasiak; Henrik Kusar; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; Pretreatment; therochemical conversion; pyrolysis; combustion; SRA - Energy; SRA - Energi; Energy Engineering;

    Abstract : Mankind has to provide a sustainable alternative to its energy related problems. Bioenergy is considered as one of the potential renewable energy resources and as a result bioenergy market is also expected to grow dramatically in future. However, logistic issues are of serious concern while considering biomass as an alternative to fossil fuel. READ MORE

  7. 5. Biomass-fuelled PEM FuelCell systems for small andmedium-sized enterprises

    Author : Tingting Guan; Per Alvfors; Mohsen Assadi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PEMFC; renewable hydrogen production; biomass; hydrogen-rich gas; biomass conversion; anaerobic digestion; steam reforming; CO removal; gasification; sustainable energy system;

    Abstract : Biomass-fuelled proton exchange membrane fuel cells (PEMFCs) offer asolution for replacing fossil fuel for hydrogen production. Through using thebiomass-derived hydrogen as fuel, PEMFCs may become an efficient andsustainable energy system for small and medium-sized enterprises. READ MORE
