• Modelling of ash melts in gasification of biomass 

      Furuvik, Nora Cecilie Ivarsdatter Skau (Doctoral dissertations at the University of South-Eastern Norway;120, Doctoral thesis, 2022-03-04)
      The need for advanced biofuels produced from sustainable sources is stressed, both on national and international level due to a global agreement to limit the Earth’s global warming. The major goals in the Norwegian agreement ...
    • Hydrogen safety in confined spaces 

      Lach, Agnieszka Weronika (Doctoral dissertations at the University of South-Eastern Norway;130, Doctoral thesis, 2022-09-02)
      Unwanted hydrogen releases in confined spaces can be significantly more dangerous compared to open-air scenarios. The transmission towards a zero-emission system results in a growth of hydrogen-driven vehicles which increases ...
    • Syngas Fermentation and Microbial Electrosynthesis Process Integration to Advance Biogas Production 

      Sivalingam, Vasan (Doctoral dissertations at the University of South-Eastern Norway;131, Doctoral thesis, 2022-09-09)
      Norway is implementing several CO2 emissions control measures to become a low-emission society by 2050. As a part of this great vision, it strives to be the first nation to end the sales of fossil-fuelled vehicles by 2025. ...
    • Cost estimation methods for CO2 capture processes 

      Aromada, Solomon Aforkoghene (Doctoral dissertations at the University of South-Eastern Norway;140, Doctoral thesis, 2022-10-12)
      Cost engineering and economic assessment play a crucial role in evaluation of CO2 capture technologies and energy systems. Cost is one of the key decisive factors when considering industrial deployment of a technology. ...

    • CO2 capture through electrified calcination in cement clinker production 

      Jacob, Ron M. (Doctoral dissertations at the University of South-Eastern Norway;170, Doctoral thesis, 2023-08-31)
      The cement industry has the second highest share of industrial CO2 emissions, and two-thirds of these emissions come from decomposing its key ingredient by the calcination reaction (CaCO3 → CaO + CO2). This thesis studied ...
    • Modelling Tool for Hydropower Systems, with Analysis and Design 

      Pandey, Madhusudhan (Doctoral dissertations at the University of South-Eastern Norway;173, Doctoral thesis, 2023-10-19)
      The increased use of renewable energy sources is due to an increasing global energy need, and to counter the effects of fossil fuels on the environment. Common renewable energy sources such as solar energy and wind energy ...
    • Accidental release of liquid CO₂ from transport and storage 

      Ibrahim, Osama Kabbashi M. (Doctoral dissertations at the University of South-Eastern Norway;174, Doctoral thesis, 2023-11-09)
      An unintended release of liquid CO2 during transport by tanks or pipelines could result in instantaneous depressurization and rapid phase transition with explosive evaporation. Under certain conditions, it could lead to a ...
    • Real-time Optimization and Control for Oil Production under Uncertainty 

      Janatian, Nima (Doctoral dissertations at the University of South-Eastern Norway;179, Doctoral thesis, 2024-02-02)
      The practical use of model-based optimization depends significantly on the accuracy of the model in use. This is because the presence of uncertainty can introduce a mismatch between the model and the real plant, which may ...
