Transition-metal-mediated electrocatalytic CO2 reduction: from nanoparticles to single-atom catalysts
(PhD Theses;709, Doctoral thesis, 2023)With the rapid development of the global economy, energy crisis and environment issues have become increasingly prominent. Carbon dioxide (CO2) is a primary greenhouse gas (CHG), while it could also be a valuable carbon ... -
Transport of CO2 In Porous Media – A Visualisation Study
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)The increase in global energy demand coupled with a need to stabilize CO2 emission levels has called for the development of a strategy with the potential to make energy `greener'. One such strategy is Carbon Capture ... -
Trends and advances in micro gas turbine technology for sustainable energy solutions: A detailed review
(Peer reviewed; Journal article, 2023)Micro Gas Turbines (MGT’s) have gained significant popularity in various energy systems due to their adaptability, low emissions, flexible structure, and ease of maintenance. Past two decades, Micro Gas Turbine (MGT) based ... -
Triaxial behavior of a stabilized and a highly porous oil well cement paste at different saturation and drainage conditions
(Peer reviewed; Journal article, 2022)Well cement is the most common barrier material in wells for geothermal and hydrocarbon production. As cements are exposed to hydrostatic loads and periods of deviatoric loading in wellbore environments, it is important ... -
Tuning the interfacial sites between copper and metal oxides (Zn, Zr, In) for CO2 hydrogenation to methanol
(Peer reviewed; Journal article, 2021)The influence of different metal oxides (ZnO, ZrO2, In2O3) in CO2 hydrogenation to methanol over Cu-based catalysts was studied. The catalysts were characterized using x-ray diffraction (XRD), thermal gravimetric analysis ... -
Twisted Elliptic Cylinder of Uncertainty: An Alternative Method to Calculate the Anti-Collision Safety Factor
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-12-04)A precise anti-collision analysis is becoming even more important in the past few years, with the increasing amount of wells being drilled in highly congested fields. The costs associated with the production fields have ... -
Two Birds with One Stone: Concurrent Ligand Removal and Carbon Encapsulation Decipher Thickness-Dependent Catalytic Activity
(Peer reviewed; Journal article, 2022)A carbon shell encapsulating a transition metal-based core has emerged as an intriguing type of catalyst structure, but the effect of the shell thickness on the catalytic properties of the buried components is not well ... -
Uncertainty analysis of Supervised machine learning predictions applied to Lithology classification
(Master thesis, 2022)Geosteering is the technique of guiding directional drilling to remain within the pay zone. This process demands a thorough survey of the lithological properties of the surrounding geo- logical strata. Since logging while ... -
Underground Storage of Natural Gas in Aquifers by Using CO2 as Cushion Gas
(Master thesis, 2022)To satisfy energy demands, the natural gas supply must be smoothed. This aim can be accomplished by means of underground natural gas storage. They provide large-scale seasonal storage of natural gas. To maintain reservoir ... -
Understanding Leakage Rates in Permanently Abandoned Wells by Studying Natural Hydrocarbon Seepages
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)Permanent plug and abandonment (PP&A) of wells is steadily becoming more important on the Norwegian Continental Shelf (NCS), as a large number of fields are approaching end of their productive life. Combining operational, ... -
