  1. 26. Förutsättningar för biogas i Europa

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

    Författare :Jonatan Wilthorn; [2020]
    Nyckelord :Biogas Europa styrmedel lönsamhet; Technology and Engineering;

    Sammanfattning : The following study addresses the future biogas production in Europe. The aim is to identify the prerequisites for growth of production and utilization of biogas as well as opportunities for profitable biogas production on an industrial scale. LÄS MER

  3. 27. Avskiljning, användning och lagring av koldioxid från biogasproduktion : Lämpliga lösningar för Tekniska verkens biogasanläggning

    Master-uppsats, Linköpings universitet/Industriell miljöteknik

    Författare :Josefine Harrius; Amanda Larsson; [2020]
    Nyckelord :Biogas; CCU; CCS; biogas production; biofuel; carbon dioxide; carbon capture and storage; carbon capture and utilization; LCA; life cycle analysis; MCA; Multi Criteria analysis; Biogas; CCU; CCS; biogasproduktion; koldioxid; lagring och användning av koldioxid; resurseffektivitet; livscykelanalys; LCA; multikriterieanalys; MKA;

    Sammanfattning : Carbon dioxide is released by natural and anthropogenic processes, such as the production and combustion of fossil fuels. Production of biogas also generates carbon dioxide, but of biogenic origin. LÄS MER

  4. 28. Analysis of Negative Emission Ammonia Fertilizer (urea) Process

    Master-uppsats, KTH/Energiprocesser

    Författare :Lucio Rodrigo Alejo Vargas; [2020]
    Nyckelord :Negative emissions; ammonia fertilizer; CO2 capture; process modelling and simulation; biogas; Negativa utsläpp; ammoniak gödsel; CO2-avskiljning; processmodellering och simulering; biogas;

    Sammanfattning : As the world population keeps increasing, ammonia-based fertilizers like urea are essential to provide food security. However, the current fertilizer industry is based on fossil fuel feedstock (mainly natural gas), making the production process CO2 emission-intensive. LÄS MER

  5. 29. Multi-criteria assessment of biomethane production from waste and residual feedstocks of Emilia-Romagna (Italy)

    Master-uppsats, SLU/Dept. of Energy and Technology

    Författare :Giovanni Zanaroli; [2019]
    Nyckelord :biomethane; nutrients recycling; anaerobic digestion; multi-criteria assessment; transport;

    Sammanfattning : Biomethane can be produced by anaerobic digestion of residues or wastes and it can be used as a renewable fuel for transport. It is associated with reduced GHG emissions, offsetting of fossil fuels and of mineral fertilizers, waste management and nutrient recycling in agriculture. LÄS MER

  7. 30. The effect of thermal pre-treatment and waste paper addition to biomethane potential of macroalgae Saccharina latissima

    Master-uppsats, Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Författare :Gadis Tandiyoputri; [2018]
    Nyckelord :Biomethane potential; Macroalgae; Saccharina latissima; mechanical pre-treatment; thermal pre-treatment;

    Sammanfattning : As a steady renewable energy technology, biogas is a viable alternative to reduce our dependency to fossil fuels and to prevent severe climate change. Biogas potential can be improved through combining different types of substrate and inoculum, as well as through substrate pre-treatments. LÄS MER
