Livsløpsanalyse av norske landbruksaktiviteter og produkter
(Master thesis, 2012)Landbrukssektoren har et betydelig miljømessig fotavtrykk, som forventes å øke ettersom verdens befolkning fortsetter å vokse. Verdenssamfunnet har derfor insentiver til å søke etter mer miljøvennlige produksjonsmetoder. ... -
Livsløpsvurdering av insektproduksjon basert på norske ressurser
(Master thesis, 2019)Den fortsatte veksten i den globale befolkningen setter et uholdbart press på verdes naturressurser, og det er ytterst nødvendig å iverksette tiltak for å sikre bærekraftig matproduksjon. Bærekraftig utvikling er avhengig ... -
Livsløpsvurdering av utbygging og utvidelse av 2-felts motorveg til 4-felts moderne motorvei
(Master thesis, 2013)Utbygging, drift og vedlikehold og avhending av veginfrastruktur blir ofte vurdert som mindre viktig for miljøbelastning fra veger, sammenliknet med belastningen som forårsakes av trafikk. I forslaget til ny Nasjonal ... -
Livssyklusanalyse av alternativene for matavfallspose i Norge, og kriterier ved valg
(Master thesis, 2023)I 2017 ble det enighet i EU om et avfallsregelverk med målsettinger for materialgjenvinning. Et av disse målene var å oppnå en materialgjenvinningsgrad på 65\% innen 2035. Som et bidrag til dette regelverket ble det pålagt ... -
LNG - Leakage, spreading and fire
(Master thesis, 2016)This master s thesis continues the line of LNG related theses in cooperation with ComputIT AS. The Phoenix series large-scale LNG pool fire experiments have been simulated using the CFD software Kameleon FireEx (KFX) for ... -
LNG anlegg drevet av kraft fra nettet: Kryogen CO2-utskilling
(Master thesis, 2008)Snøhvit Tog I på Melkøya er verdens første LNG-anlegg hvor kjølekompressorene drives elektrisk, med kraft produsert fra et kraftvarmeverk. Det vurderes nå utbygging av et Snøhvit Tog II hvor kjølekompressorene skal drives ... -
LNG Bunkering Operations: Establish probabilistic safety distances for LNG bunkering operations.
(Master thesis, 2014)The environmental and economical advantages of using LNG as marine fuel have been recognized by the industry. In response to increasing demand, construction of LNG bunkering infrastructure is under rapid development. Several ... -
Load Modelling of Buildings in Mixed Energy Distribution Systems
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:78, Doctoral thesis, 2007)The main topic of this thesis has been the development of a new method for load modelling of buildings in mixed energy distribution systems. The method estimates design load profiles, yearly load profiles, load duration ... -
Local and non-local drivers of consumption-based water use in China during 2007–2015: Perspective of metacoupling
(Peer reviewed; Journal article, 2022)Increasingly growing consumption-based water use (WU) combined with climate change have exacerbated water stress globally and regionally, yet little is known about how the WU change is affected by metacoupled processes ... -

Local entropy generation and entropy fluxes of a transient flame during head-on quenching towards solid and hydrogen-permeable porous walls
(Peer reviewed; Journal article, 2021)Premixed H2-air flames are studied in a one-dimensional wall-bounded configuration. The laminar flame propagates towards and quenches at a wall that is either solid or permeable. Entropy generation by each of 19 elementary ... -
Local Heating Networks with Waste Heat Utilization: Low or Medium Temperature Supply?
(Peer reviewed; Journal article, 2020)District heating enables an economical use of energy sources that would otherwise be wasted to cover the heating demands of buildings in urban areas. For efficient utilization of local waste heat and renewable heat sources, ... -
Low Aerodynamic Drag Suit for Cycling - Design and Testing
(Master thesis, 2015)The focus on garment aerodynamics is increasing in high velocity sports where aerodynamics are crucial such as cycling, speed skating and alpine skiing. Recently published research show that a low drag suit manipulating ... -
Low Temperature Applications for CO2 Capture in Hydrogen Production
