Microbial behavior and hydrogen consumption of Oleidesulfovibrio alaskensis - Implications for subsurface hydrogen storage
(Master thesis, 2023-06-01)To reduce global warming an energy transition going from fossil fuel to renewable energy is required and energy storage opportunities to store surplus electricity are needed. Hydrogen gas (H2) is an energy carrier and can ... -
Miljøpåvirkninger fra produksjon og bruk av hydrogen i maritim transport
(Master thesis, 2020-07-01)I denne studien er hydrogen foreslått som et alternativt drivstoff for maritim transport. Miljøpåvirkninger fra å erstatte konvensjonelle fossile brensler i sjøtransport med hydrogen vurderes ved å utføre en livssyklusvurdering ... -
Modification and Analysis of a Multimegawatt Floating Spar Wind Turbine
(Master thesis, 2021-11-22) -
Monitoring Soil Moisture Drought over Northern High Latitudes from Space
(Peer reviewed; Journal article, 2019-05-20)Mapping drought from space using, e.g., surface soil moisture (SSM), has become viable in the last decade. However, state of the art SSM retrieval products suffer from very poor coverage over northern latitudes. In this ... -
Numerical Investigation of a Radially Cooled Turbine Guide Vane Using Air and Steam as a Cooling Medium
(Master thesis, 2021-06-01)Gas turbine performance is closely linked to the turbine inlet temperature, which in turn is limited by the turbine guide vanes ability to withstand the massive thermal loads. To improve the efficiency in modern high-temperature ... -
Numerical Investigation of the Use of Nanofluid in a Photovoltaic Thermal System
(Master thesis, 2022-06-01) -
Numerical Simulation of Nanofluid Cooling in a Single-Cylinder Diesel Engine
(Master thesis, 2023-06-01) -
Oceanic heat transport towards Getz Ice Shelf, Amundsen Sea
(Master thesis, 2019-12-11)Two years of mooring data from a trough leading up to one of the central ice shelf fronts of the Getz Ice Shelf, Western Amundsen Sea, are used to describe the local hydrography and currents, their variability and possible ... -
Offshore wind power and hydrogen for oil and gas platform electrification
(Master thesis, 2022-06-01) -
Oil Spill Modeling in Sea Ice Covered Ocean
(Master thesis, 2021-06-01)The ongoing reduction in extent and thickness of sea ice in the Arctic allows the expansion of shipping activity and oil exploration in the high north, and with that a potential increased risk of oil spill in ice covered ... -
Ombygging av en én-sylindret dieselmotor til dual fuel-drift og testing av alternative gassformede drivstoff
(Master thesis, 2020-06-26)Denne rapporten beskriver ombygging av en én-sylindret dieselmotor til dual fuel-drift, og videre testing av alternative gassformede drivstoff. I tillegg omhandler rapporten simuleringer gjort på samme motor ved hjelp av ... -
On the use of a new mathematical formulation for loads- and motion analysis of a mooring line
(Master thesis, 2023-11-20)This master thesis investigates the use of a new mathematical model for calculating loads and dynamic motion of a mooring line. Current industry standard mooring analysis tools uses a lumped parameter modelling approach. ... -
On the use of car observations to evaluate and improve road weather forecasting
(Master thesis, 2023-06-01) -
Optimal location of charging stations for electric vehicles
(Master thesis, 2023-11-20)The electrification of road transportation requires a massive investment in charging infrastructure to keep up with the demand for underway charging. A substantial research effort is put into the problem of finding optimal ... -
Optimizing maintenance plans of offshore wind farms by calculating the likelihood of future turbine failures
(Master thesis, 2022-06-01)Although offshore wind power shows promising energy potentials, high cost of operating and maintaining offshore wind farms concerns investors. Different maintenance strategies are applied by wind farm operators to overcome ... -
