  4. 33. Opportunities and uncertainties in the early stages of development of CO2 capture and storage

    Författare :Mårten Lind; Mats Westermark; Mohsen Assadi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acceptance; cement; CCS; CO2 capture and storage; early opportunities; enhanced oil recovery; expert opinions; hybrid power cycles; optimism; oxyfuel combustion; pressurised fluidised bed combustion; pilot plant; potassium carbonate; risk; Sargas; scenario studies; scientific uncertainty; stakeholder perceptions; Chemical process and manufacturing engineering; Kemisk process- och produktionsteknik;

    Sammanfattning : The topic of this thesis is carbon dioxide (CO2) capture and storage (CCS), which is a technology that is currently being promoted by industries, scientists and governments, among others, in order to mitigate climate change despite a continued use of fossil fuels. Because of the complex nature of CCS and the risks it entails, it is controversial. LÄS MER

  5. 34. Towards Changeability Quantification for Product-Service Systems Design

    Författare :Raj Jiten Machchhar; Alessandro Bertoni; Johan Wall; Fredrik Elgh; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Changeability quantification; early design; Uncertainty; Value robustness; Operational Scenario; Product-Service Systems; Systems Engineering.; Maskinteknik; Mechanical Engineering;

    Sammanfattning : Tough competition and volatile global markets have pushed the manufacturing industries to develop solutions more customer-centric with optimal utilization of resources. One of the key reasons behind developing a customer-centric solution is the increased customer value that imparts a competitive edge to the manufacturing industries, eventually leading them to sustain their businesses.
