The Norwegian energy system has traditionally had an energy surplus with a large share of hydro power. Due to increasing demand of power from large scale electrification, the power system is estimated to experience hours of national power deficient in 2030 even with moderate increase of consumption. Extensive increase of variable production renewable power from wind and solar in Northern Europe has ...

Carbon capture and storage (CCS) has been proposed as one of the alternatives for climate mitigation. CCS is a process where CO2 is trapped from large point sources, transported to a storage location and injected into storage reservoirs. One of the alternatives for CO2-storage is underground geological storage. Characterizing such an underground reservoir is crucial for safe storage, where leakage ...

Økt konkurranse fra andre fornybare energikilder, økt energibehov og økt behov for reguleringsevne stiller stadig større krav til eksisterende og nye vannkraftverk. Vannkraftsektoren har de siste hundre årene ikke opplevd reell konkurranse fra andre teknologier her til lands, og har derfor ikke blitt tvunget til innovasjon og nytenking i samme grad som andre deler av kraftnæringen. De siste årene ...

Since 1999, the Pine Wood Nematode (PWN) has spread, infected and damaged growing areas of pine forest in Portugal. The pest is subject to strict quarantine measures, that require forest owners to register, fell and dispose of infected trees. As remote sensing from satellites provides repetitive and consistent data sets with high temporal resolution and large spatial coverage, a surveillance based ...

The objective of this master's thesis is to investigate the current and future technical and economic feasibility of PV systems for marine applications. Two scenarios will be studied; a land-based PV power station to supply an in-land ferry in Norway and a PV system installed on a wind farm support vessel as a supplementary power source. The two scenarios are use cases that support the two research ...

This thesis presents the possibilities for using shallow geothermal energy for heating purposes in Ny-Ålesund. The current energy supply in Ny-Ålesund is a diesel generator, which does not comply with the Norwegian government and Ny-Ålesund Science Managers Committee’s common goal to maintain the natural environment in Ny-Ålesund. Ny-Ålesund has a potential for replacing the heat from the current ...

The focus of this thesis is to do ice-water classification on Sentinel-1 EW SLC imagery using an unsupervised Mixture of Gaussian segmentation algorithm. The classes are automatically labelled as sea ice or water based on the slope of the observed brightness decay from near- to far-range, which is different for sea ice and water. The aim of the thesis is twofold. In the first part, the ability of ...

In the vicinity of the Snøhvit hydrocarbon reservoir in the Hammerfest Basin a number of fluid flow phenomena occur, e.g. free gas accumulations, pockmarks and potential indicators of gas hydrates.The presence of shallow gas may cause major blowouts during drilling. To reduce the risk, it is important to locate the shallow gas and gas hydrates. CO2 has been injected into the Snøhvit reservoir since ...

To contribute to the reduction of greenhouse gas emissions, energy production from renewable energy resources should be markedly increased to supply the rising global energy demand (Marchant, 2018). This thesis investigates the solar energy potential in Tromsø which is used as a basis for estimating total energy yield from photovoltaic (PV) systems on rooftops. The energy yield is compared against ...

Multistråle batymetriske data og seismiske profiler fra den vestlige kysten av Finnmark er analysert med formålet om å rekonstruere dynamikken til det Fennoskandiske Isdekket gjennom siste glasiale maksimum, og påfølgende deglasiasjon. Fokuset har vært på tre prograderende kiler i forlengelsen av de glasiale trauene Rolvsøy-, Hjelmsøy- og Måsøytrauet. En seismisk stratigrafi er definert med tre ...
