Challenges related to storage and transfer of solar energy with a case study on long distance power transfer
(The University of Bergen, 2010-06-21)
The challenges that will be discussed in this thesis are two-fold; the problems related to trans- mission of power over long distances, and the need for energy storage, especially at night. Both of the issues are accentuated ...
Catalysts for Enhanced CO2-CH4 Exchange in Natural Gas Hydrates. An experimental feasibility study of exchange enhancement by use of chemical additives
(The University of Bergen, 2013-06-01)
Gas hydrate is a solid state of gas and water at high pressure and low temperature conditions. Vast energy potential is associated with gas hydrates and extensive on-going research aims at addressing the technical viability ...

Correlated ionization processes in atoms and molecules
(The University of Bergen, 2013-09-27)
This thesis is composed of five scientific papers written between 2009 and 2013. The focus of this work is on various photo-ionization processes in small atoms and molecules. The strong field phenomenon called “atomic ...
Fundamental aspects of water methane separation in zeolites
(The University of Bergen, 2013-06-03)
The main objective of this thesis was to use molecular dynamics to investigate the methane interactions with zeolite, specifically the Linde Type A-3A, alongside with an investigation into the use of polynomial path ...
Sound velocity cell for gas characterization

Low-energy surface vibration measurements on the alpha-quartz (0001) surface
(The University of Bergen, 2011)
Despite the enormous range of usages, only little is known about the dynamic and structural properties of quartz (SiO2) surfaces on the atomic scale. The main reason for this is probably that quartz is an insulator, with ...
Bestemmelse av egenskaper til piezoelektriske skiver med lavt diameter/tykkelse forhold
(The University of Bergen, 2009-11-20)
Oppgaven tar for seg mekaniske, elektriske og akustiske målinger i luft på piezoelektriske skiver av typen PZT-5A med et diameter/tykkelsesforhold på 7.5. Målingene blir sammenlignet med teoretiske modeller for skivenes ...
Økt oljeutvinning i kalk basert på vannkjemi og potensialbestemmende ioner for endring av fukt
(The University of Bergen, 2010-06-01)
Om lag 50 % av verdens oljereserver ligger lagret i karbonatreservoarer. Slike reservoarer har ofte en fukt som ligger i området fra nøytralt fuktet til moderat oljefuktet. Nøkkelmekanismen for høy oljeutvinning ved ...
Low Salinity Waterflood in Combination with Surfactant/Polymer: Effect of Brine Composition
(The University of Bergen, 2014-06-02)
The effect of low salinity water (LSW) on enhanced oil recovery has been known for decades. Although much research is done on the topic, a general agreement of the prevailing mechanism for the low salinity effect has still ...
