Emission Free North Sea: A Study of Alternative Solutions for Power Generation on Offshore Installations
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-06-15)As a contribution to the 2°C goal of the Paris Agreement, The Norwegian Oil and Gas Association aims to reduce their GHG emissions to 40% of the 2005 level by 2030 and to have zero emissions by 2050. Gas turbines producing ... -
Emission Mitigation and Energy Security Trade-Off: Role of Natural Gas in the Indian Power Sector
(Peer reviewed; Journal article, 2021-06)India’s Nationally Determined Contributions (NDC) aim to increase the share of non-fossil fuel, especially renewables, in power generation. But at the same time, it mentions that coal is likely to dominate the power ... -
En beskrivelse av ulike trykkontroll metoder
(Bachelor thesis, 2023)I industrien finnes det to hovedmetoder for håndtering av kick, og valg av metode avhenger i stor grad av selskapets prosedyrer. Derfor er det relevant å undersøke forskning som er gjort på området for å identifisere en ... -
Enabling Increased Delithiation Rates in Silicon-Based Anodes through Alloying with Phosphorus
(Peer reviewed; Journal article, 2022)The capability of battery materials to deliver not only high lithium storage capacity, but also the ability to operate at high charge/discharge rates is an essential property for development of new batteries. In the present ... -
Enabling long cycle life lithium-ion capacitors through electrode-electrolyte interface optimization
(PhD thesis UiS;749, Doctoral thesis, 2024)Electrode-electrolyte interfaces in electrochemical cells represent critical boundaries between the electrode and electrolyte where most charge transfer or storage processes are initiated. Accordingly, the interface ... -
Energibrønner
(Bachelor thesis, 2023)Det foreligger i dag et stort behov for å finne nye grønne energikilder som er bærekraftige. Vi trenger nye energikilder som ikke påvirker miljøet negativt og som i tillegg gir stabil tilførsel av energi gjennom hele året. ... -
