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 ... -
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 ... -
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 ... -
Low-level jet height’s impact on wind turbine loads: A case study
