Hydroelectric Power in Present and Future Energy Systems
(Master thesis, 2013-06-03)To be able to understand the dynamics of energy systems, the interplay between a variety of factors affecting them has to be addressed. In this thesis, we look at issues like climate change, energy policy, power transmission, ... -
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 ... -
Hydrogen Relative Permeability Hysteresis in Underground Storage
(Journal article; Peer reviewed, 2022)Implementation of the hydrogen economy for emission reduction will require storage facilities, and underground hydrogen storage (UHS) in porous media offers a readily available large-scale option. Lack of studies on ... -
Hydrogeologi og karstkorrosjon i Grønli-Seterakviferen, Mo I Rana
(Master thesis, 2002)Nykartlegging av grottesystemet ga en total lengde på 7,6 km (Grønligrotta – 4 100 m, Setergrotta – 3 020 m og Langgrotta-Isgrotta - 440 m). Den aktive akviferen under de tørrlagte grottene er undersøkt hovedsakelig ved ... -
Hydrography and circulation in the Filchner Depression, Weddell Sea, Antarctica
(Peer reviewed; Journal article, 2014)Cold and dense ice shelf water (ISW) emerging from the Filchner-Ronne Ice Shelf cavity in the southwestern Weddell Sea flows northward through the Filchner Depression to eventually descend the con- tinental slope and ... -
Hydrography in the Nordic Seas During Dansgaard-Oeschger Events 8-5
(Doctoral thesis, 2019-06-14)The modern rapidity of Arctic sea ice loss and rise in Arctic air and ocean temperatures is pushing research to understand mechanisms for abrupt climate fluctuations. Resolving the mechanisms of past abrupt changes is a ... -
Hydrography, circulation, and response to atmospheric forcing in the vicinity of the central Getz Ice Shelf, Amundsen Sea, Antarctica
(Journal article; Peer reviewed, 2022)Ice shelves in the Amundsen Sea are thinning rapidly as ocean currents bring warm water into the cavities beneath the floating ice. Although the reported melt rates for the Getz Ice Shelf are comparatively low for the ... -
Hydrography, transport and mixing of the West Spitsbergen Current: the Svalbard Branch in summer 2015
(Peer reviewed; Journal article, 2018-12-21)Measurements of ocean currents, stratification and microstructure were made in August 2015, northwest of Svalbard, downstream of the Atlantic inflow in Fram Strait in the Arctic Ocean. Observations in three sections are ... -
Hydrological Modelling of Ethiopian Watersheds : The Application of Hydrological Models for Flow Forecasting and Analysis of Sensitivity to Climate and Landuse Changes
(Doctoral thesis, 2019-10-15)Hydrological modelling studies vary depending on the purpose, data availability and number of outputs required. Quantifying the hydrological responses to various human- and climate-induced changes requires different modelling ... -
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 ... -
Hydrostatiske og hydrodynamiske egenskaper til et semilukket oppdrettsanlegg
(Master thesis, 2021-06-01)Målet med masteroppgaven er å kartlegge førsteordens hydrodynamiske responser en nedskalert forenklet modell av OceanTECH-anlegget har, under tre ekstreme sjøtilstander. I den forbindelse er det gjort både eksperimentelle ... -
Hydrotermisk omdanning av biorest fra Bergen biogassanlegg og analyse av produkt ved EA, GC-MS, IR og NMR
(Master thesis, 2019-12-20)Verdens energibehov og bruken av fossile brensler øker. Dette fører til økt interesse for fornybare og bærekraftige energikilder. Biomasse er, ved riktig og fornuftig bruk, et godt alternativ til en slik energikilde. ... -
Hydrotermisk omdanning av biorest fra biogassanlegget i Rådalen og analysering av produkter ved EA, GC-MS, IR og SPE
(Master thesis, 2019-12-20)I løpet av de siste årene har fokuset på de globale klimaendringene økt kraftig. Dette har ført til mer miljøvennlige metoder for å behandle avfall. Bergen Kommune har etablert et anlegg som produserer biogass fra kloakkslam ... -
