  1. 1. Techno-economic evaluation of hydrochar via hydrothermal carbonisation of organicresidues

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Abdirahman Abdullahi; [2022]
    Nyckelord :Technoeconomic analysis; energy system modelling; HTC; hyrochar; system integration; OSMET;

    Sammanfattning : This thesis has investigated the techno-economic feasibility of upgrading the sludge from a chemical pulp mill to hydrochar via hydrothermal carbonization (HTC). The intended use of the hydrochar was to replace fossil coal within metallurgical applications in the iron and steel industry. LÄS MER

  2. 2. Bio-LNG and CO2 liquefaction investment for a biomethane plant with an output of 350 Nm3/h : A techno-economic-environmental analysis

    Master-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Lars-Julian Vernersson; [2022]
    Nyckelord :Biomethane liquefaction; Carbon dioxide liquefaction; Biogas upgrading; Liquefaction economy; Biomethane life cycle assessment; Biomethane greenhouse gas saving potential; Biomethane emission factor.;

    Sammanfattning : Stricter requirements from the European Union and the German government regarding the utilization of renewable and sustainable fuels for transportation, power, and heat production are currently in effect. This has led to that heavy transportation companies are looking for a more sustainable alternative to liquefied natural gas, such as liquefied biomethane. LÄS MER

  3. 3. Klimatpåverkan och energianvändning vid tillämpning av bio-CCS och bio-CCU från biogasanläggningar

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

    Författare :Emelie Wallman; [2022]
    Nyckelord :livscykelanalys; koldioxid; biometan; power to gas; biologisk metanisering; katalytisk metanisering; elektrolys;

    Sammanfattning : To mitigate the human-induced climate change, Sweden has adopted a climate policy framework that states a net-zero emissions of greenhouse gases by the year of 2045 and thereafter negative emissions. To achieve this goal extensive emission mitigation alongside supplementary measures are required. LÄS MER

  4. 4. Greening of Global Value Chains: from a topdown and bottom-up perspective A multiple-case study of how GVC actors are addressing greening of GVCs through reducing CO2 emissions from road transports

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Alicia Elovsson Hentschel; Frida Zetterberg; [2021-06-28]
    Nyckelord :Global Value Chains; Greening; Sustainability governance; Environmental upgrading; Road transport; CO2 emission; Fossil-free fuels;

    Sammanfattning : Previous literature within the GVC research field have mainly focused on economic values, however, recently environmental aspects have increasingly started to be considered. Nevertheless, although road transport is a major cause of CO2 emissions, it has been overlooked in the context of greening GVCs. LÄS MER

  5. 5. Bio-CCS från biogasanläggningar : Modellering av distributionssystem för CO2

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

    Författare :Karin Berg; [2021]
    Nyckelord :logistik; transport; koldioxid; distributionskostnad; energianvändning; vägtransport; rörledning; lagring;

    Sammanfattning : Negative emissions of greenhouse gases will be essential for reaching the goal of net-zero emissions by 2045. Carbon Capture and Storage (CCS) is a technique that collects CO2 with the purpose to permanently store it outside of the atmosphere. LÄS MER
