High Voltage Direct Current Transmission
(Master thesis, 2019-07-02) -
High Voltage Laboratory Development: An in-depth Description and Report on the Process of Fabricating a Faraday Cage
(Master thesis, 2022-12-16)This thesis examines the quality of protection a Faraday cage provides against electromagnetic fields. The necessary theory to examine and calculate the shielding effectiveness of a Faraday cage, discuss obtained results ... -
Hydrogen Consumption by Halophilic Microorganisms - Implications for Underground Hydrogen Storage
(Master thesis, 2023-06-01)Underground Hydrogen Storage (UHS) in reservoirs and caverns is a possible solution for large-scale and long-term storage of hydrogen (H2) in the subsurface. As the cost of tech- nology installation and electricity from ... -
Hydropower Production Scheduling using Stochastisc Dual Dynamic Programming subject to environmental constraints
(Master thesis, 2019-06-22)Oppgaven utforsker vannkraftproduksjonsplanlegging i Bergsdalen vassdraget, styrt av BKK, ved hjelp av Stokastisk Dual Dynamisk Programmering. Systemet er under et sett med miljørestriksjoner, innført av NVE, som utfordrer ... -
Idealized Modeling of the North Icelandic Jet
(Master thesis, 2023-06-01)The North Icelandic Jet (NIJ) is a crucial component of the lower limb of the Atlantic Meridional Overturning Circulation, supplying one-third to one-half of the overflow water transport through Denmark Strait, including ... -
Ignition of high-pressure hydrogen releases – Experimental study of impinging and non-impinging releases through a fast-acting valve, with and without a burst disc downstream of the valve
(Master thesis, 2021-09-14)A wide consensus of climate research indicates that anthropogenic greenhouse gas emissions affect the climate and causes the global mean temperature to rise compared to preindustrial levels. International treaties such as ... -
Impacts on carbon budgets of increased use og Norwegian forest resources for energy
(Master thesis, 2019-06-19)When forests are logged for heat and electricity production, emissions from burning of the biomass are not accounted for in national greenhouse gas reporting to the climate convention. This would have been correct if a ... -
Investigation of the dynamic response of a spar FOWT, and its sensitivity to variations in draft
(Master thesis, 2020-06-30)The objective of this thesis is to investigate how the dynamic properties of a spar supported FOWT change when the draft is reduced, and what draft is needed in order to support a 10 MW wind turbine. Design solutions of ... -
Karbondynamikk i Grønlandshavet observert av en Argobøye og en 1-D Blandingsmodell
(Master thesis, 2023-06-02) -
Life cycle assessment of hydrogen fuel in aviation
(Master thesis, 2020-07-01)The aviation sector emits 2% of the global emissions caused by transportation. This is a problem for our global climate and has also shown to be an issue for the public after the Swedish boycott of airtravel, inspired by ... -
Long-term changes in the Nordic Seas' hydrographic structure and overflow waters
(Master thesis, 2020-06-30)A collection of historical hydrographic data was used to examine the hydrographic properties of the water masses in the Nordic Seas from 1950 to 2018, with particular focus on the dense overflows from the Nordic Seas. ... -
Low-level jet height’s impact on wind turbine loads: A case study
(Master thesis, 2023-06-01)Over the years, wind turbines have been steadily increasing in size, with newer models boasting larger dimensions. For instance, the diameter of an installed prototype offshore wind turbine in late 2022 was over 200 m, ... -
MARINE PLASTIC DRIFT FROM THE MEKONG RIVER TO SOUTHEAST ASIA
(Master thesis, 2022-11-21)Plastic waste has been identified as a major worldwide environmental issue (Sun et al., 2021; Zhang et al., 2020). Jambeck et al. (2015) estimated that between 4.8 and 12.7 million tons of plastic waste enters the ocean ... -
Measurement and Modelling of Underwater Acoustic Noise induced by Offshore Wind Turbines under the Effects of Varying Oceanic and Sea-State Conditions
(Master thesis, 2022-06-01)In this thesis, we have performed several processing methods for analysing available hydrophone data. This was done in order to study the sound pressure levels in the vicinity of an offshore wind farm, and to identify ... -
Mesoscale variability of the Antarctic slope front and the slope front current
(Master thesis, 2022-06-01)The Weddell Sea is essential for the global climate due to the production of the dense shelf water that contributes to the Weddell Sea Bottom Water (WSBW), feeding the lower limb of the global thermohaline circulation (Orsi ... -
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 ... -
