Hybrid life cycle assessment at the neighbourhood scale: The case of Ydalir, Norway
(Peer reviewed; Journal article, 2022)The focus of this study is Ydalir, a neighbourhood in Norway currently in the early planning stages. Ydalir aims to produce its energy locally based on renewable sources, has passive house standards or higher for all its ... -
Hybrid life cycle assessment of steel production with carbon capture and storage
(Master thesis, 2013)Among several Green house gases, CO2 is a main contributor and accounts for about 60% of the greenhouse effect because of its huge emission amount. The iron and steel sector has showed one of the largest energy intensity ... -
Hybrid Life Cycle Assessment of Wood-based Biofuel Production and Consumption Scenarios in Norway
(Master thesis, 2008)An increasingly urgent need to develop alternatives to fossil fuels in road trans- portation stems from both the need to combat climate change and the need to prepare for a transition beyond peak oil. Biofuels can be part ... -
A hybrid machine learning approach for the load prediction in the sustainable transition of district heating networks
(Peer reviewed; Journal article, 2023)Current district heating networks are undergoing a sustainable transition towards the 4th and 5th generation of district heating networks, characterized by the integration of different types of renewable energy sources ... -
Hybrid park at Stokkfjellet; Combining solar and wind power in the same grid
(Bachelor thesis, 2023)Denne oppgaven analyserer tre alternativer for drift av en foreslått hybridpark ved et allerede eksisterende vindkraftverk på Stokkfjellet. Dette gjøres ved å simulere et PV-system og utforske tre forskjellige scenarioer ... -
Hybrid ventilasjon i moderne bygninger
(Master thesis, 2015)I bygningsindustrien blir det satt stadig strengere krav vedrørende energibruk og energieffektivitet. Samtidig er et godt inneklima viktig. Hybride mixed-mode løsninger er de siste årene lansert som et alternativ til ... -
Hybridization of complete PLCA and MRIO databases for a comprehensive product system coverage
(Peer reviewed; Journal article, 2020)Process‐based Life Cycle Assessments (PLCA) rely on detailed descriptions of extensive value chains and their associated exchanges with the environment, but major data gaps limit the completeness of these system descriptions ... -
Hydraulic design of a turbine for energy recovery purposes
(Master thesis, 2023)Denne masteroppgaven fokuserer på design og analyse av en komplett Francis turbin for Framo AS med formål om energiutvinning i offshore-applikasjoner. Turbindesignet skiller seg fra konvensjonelt design ved at den ikke har ... -

(Master thesis, 2023)Denne masteroppgaven fokuserer på design og analyse av en komplett Francisturbin for Framo AS med formål om energiutvinning i offshore-applikasjoner. Turbindesignet skiller seg fra konvensjonelt design ved at den ikke har ... -
Hydraulic Design of Francis Turbine Exposed to Sediment Erosion
(Master thesis, 2011)Sediment erosion is a large problem for turbines operated in sand laden water, especially in the Himalayas and the Andes Mountains, where the contents of hard minerals in the rivers are high. A program called RenewableNepal ... -
Hydraulic design of Francis turbine exposed to sediment erosion
(Master thesis, 2012)High concentrations of sediments is a serious problem for hydropower stations in the Himalayas and the Andes Mountains. For run-of-river power plants sediment causes heavy erosion even with settling basins. This leads to ... -
Hydraulic resistance, shock wave attenuation and gaseous detonation extinction in granular materials
(Doktoravhandlinger ved NTNU, 1503-8181; 65, Doctoral thesis, 2002)Military and civil installations can be equipped with a granular filter, for example in air inlet systems to protect against blast waves. Granular filters also have a certain potential to replace shock valves and to work ... -
Hydraulic scale modelling and thermodynamics of mass oscillations in closed surge tanks
(Journal article; Peer reviewed, 2015)The design and results from a hydraulic scale model of mass oscillations in a hydropower plant with a closed surge tank constructed as an underground rock cavern are presented. The results from the model test of an existing ... -
Hydrodynamic and magnetohydrodynamic turbulence : some numerical experiments
