  1. 11. Förutsättningar och affärsmodeller för avsättning av småskaligt producerad fordonsgas

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Energy and Technology

    Författare :Mikaela Blom; [2016]
    Nyckelord :biogas; tankning; regelverk; gårdsanläggning; aktörskartläggning; ekonomiska förutsättningar; småskalig uppgradering;

    Sammanfattning : There is a need for reducing greenhouse gas emissions from the transporting sector. With a potential of 3-7 TWh per year, farm based production of biomethane can be a solution for this problem. The small farm based biogas plants have a problem using the produced heat in an efficient way and today 29 % of the biogas is flared or not used. LÄS MER

  2. 12. Utredning om uppgraderingstekniker av biogas för en biogasanläggning

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Jonathan Larsson; [2016]
    Nyckelord :Biogasuppgradering; vattenskrubber; membranteknik; koldioxidborttagning; ekonomisk studie; miljöstudie; fordonsgas;

    Sammanfattning : The biogas production in Sweden year 2014 was 1,8 TWh where almost 1 TWh was upgraded to biomethane for use in vehicles. The production of biomethane is mainly located at the biogas plants that have a production over 200-400 Nm3/h. LÄS MER

  3. 13. Enhancing the production of biomethane : A comparison between GoBiGas process and new process of combining anaerobic digestion and biomass gasification

    Master-uppsats, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Daheem Mehmood; [2016]
    Nyckelord :Aspen Plus; Biomethane; Biomass; Cold gas efficiency; GoBiGas process; Gasification; GoBiGas model;

    Sammanfattning : In recent years, there is a rapid growing interest in the use of biomethane for the transport sector. A new method of combining anaerobic digestion and biomass gasification is proposed.The feasibility study shows that more biomethane can be produced; resulting in an increase in the revenue compared to individual biogas plants.

  4. 14. Feasibility Study of Production of Bio Methane from Bio Wastes in Sri Lanka and Develop Cost Model for the Production Process

    Magister-uppsats, Högskolan i Gävle/Energisystem

    Författare :Ambagaha Pathirage Thanushka Sandaruwan Peiris; [2016]
    Nyckelord :Renewable Energy; Anaerobic Digestion; Biogas; Biomethane; Cost Model; Investment Decision Tool; Feasibility Study; Sri Lanka;

    Sammanfattning : Generation of wastes as a result of expanding economic activities and change life styles of people is on the increase from recent times in Sri Lanka, especially in urban areas. The government authorities, both national and provincial, have no firm plans to manage the generation of wastes as well as safe disposal of unavoidable wastes. LÄS MER

  5. 15. An Evaluation of the Performance of the GoBiGas Gasification Process

    H-uppsats, Chalmers tekniska högskola/Institutionen för energi och miljö

    Författare :Malin Karlbrink; [2015]
    Nyckelord :GoBiGas; indirect gasification; gasification; DFB; biomass; bio-SNG; biogas;

    Sammanfattning : The GoBiGas (Gothenburg Biomass Gasification) project was initiated by Göteborg Energi toenable biogas/bio-SNG production through gasification of biomass from forest residuals. Thepurpose of GoBiGas is to gain knowledge, at a pre-commercial scale, within gasification offorest residues as well as methanation for the purpose of producing biomethane of sufficientquality to be distributed in the conventional gas grid.
