  1. 1. Towards Sustainable Shipping: Climate change and other environmental perspectives on carbon-based marine electrofuels and onboard carbon capture

    Författare :Elin Malmgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; liquefied natural gas; power-to-X; methanol; power-to-gas; carbon capture and utilization; thematic analysis; Marine renewable energy; onboard carbon capture; marine fuels; LCA; shipping; electrofuels;

    Sammanfattning : The global, local, and regional environment is under pressure from human activity. Shipping is a human activity causing emissions to air, water, and soil, which has direct and indirect effects on the environment. LÄS MER

  3. 2. Utilizing CO2 from biomethane production : Sustainability and climate performance

    Författare :Stephanie S. Cordova; Mats Eklund; Marcus Gustafsson; Niclas Svensson; Valentina Bisinella; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomethane; Carbon capture and utilization; CCU; CO₂ utilization;

    Sammanfattning : Biogas solutions offer many benefits for the environment and society, including organic waste treatment as well as being an enabler for energy and nutrient recovery. The products of anaerobic digestion are a biogas, which contains a share of 30 to 50% carbon dioxide (CO2) and 50 to 70% methane, and a liquid remanent, rich in nutrients. LÄS MER

  4. 3. Towards sustainable shipping: Evaluating the environmental impact of electrofuels

    Författare :Elin Malmgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; environmental assessment; LCA; emerging technology; marine fuels; human health; future fuel; sustainable shipping; carbon utilization; power-to-x; carbon capture;

    Sammanfattning : The global, local, and regional environment is under pressure from human activity. Changes in the environment can be beneficial and strived for, but environmental and health problems need to be considered when we design human activities. LÄS MER

  5. 4. Life cycle navigation through future energy carriers and propulsion options for the energy transition in shipping

    Författare :Fayas Malik Kanchiralla; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; environmental impact; life cycle costing; battery electric; fuel cells; electro-fuel; technical feasibility; economic impact; hydrogen; life cycle assessment; carbon capture; marine fuel; engines; ammonia; carbon abatement cost; shipping; methanol;

    Sammanfattning : The shipping industry's heavy reliance on fossil fuels has a detrimental effect on the global climate, human health, and the natural environment. The shipping sector now relies on the use of cheap and energy-dense heavy fuel oil and is perceived as ‘difficult-to-decarbonize’. LÄS MER

  7. 5. Partial carbon capture – an opportunity to decarbonize primary steelmaking

    Författare :Max Biermann; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; excess heat; amine absorption; partial CO2 capture; process industry; cost estimation; CCS; steel making;

    Sammanfattning : Climate change requires that all energy-related sectors drastically reduce their greenhouse gas emissions (GHG). To have a high likelihood of limiting global warming to 1.5°C, large-scale mitigation of GHG has to start being implemented and cause emissions to fall well before Year 2030. LÄS MER
