Hydropower operations in groundwater-influenced rivers: implications for Atlantic salmon, Salmo salar, early life stage development and survival
(Journal article; Peer reviewed, 2016)During their early life stages (egg maturation, hatching, alevin development), between late autumn and early spring, young Atlantic salmon are exposed to surface-groundwater interactions in the hyporheic zone and may depend ... -
Hydropower optimization using model-based Reinforcement Learning
(Master thesis, 2023)En av de mest effektive måtene å lagre energi på er ved å planlegge produksjonen av vannkraft slik at kraft produseres når det er mest gunstig og at vannet i andre perioder reserveres. I det nordiske kraftmarkedet prøver ... -
Hydropower Production in Future Climate Scenarios: The Case for Kwanza River, Angola
(Journal article; Peer reviewed, 2016)Climate change is altering hydrological processes with varying degrees in various regions of the world and remains a threat to water resources projects in southern Africa. The likely negative impacts of changes in Africa ... -
Hydropower Production in Future Climate Scenarios; the Case for the Zambezi River
(Journal article; Peer reviewed, 2016)Climate change remains a threat to water resources projects in southern Africa where impacts resulting from changes in climate are projected to be negative and worse than in most other regions of the world. This work ... -
Hydropower Project Ventures: Testing International Waters
(Journal article; Peer reviewed, 2012)A vanguard project is an effective mechanism for testing new opportunities to deploy existing technologies into new markets in an effort to realize growth. Typically such endeavors are motivated by organizational needs to ... -

Hydropower Providing Flexibility for a Renewable Energy System: Three European Energy Scenarios
(Report, 2018)The Horizon 2020 Project ‘Increasing the value of Hydropower through increased Flexibility (HydroFlex)’ aims towards scientific and technological breakthroughs to enable hydropower to operate with very high flexibility in ... -
Hydropower reservoir management using multi-factor price model and correlation between price and local inflow
(Journal article, 2018)Hydropower producers with reservoir capacity have a special challenge when it comes to weighing the short-term profit from selling power in the day-ahead spot market against waiting for better electricity prices. In this ... -
Hydropower Resource Curse?
(Doctoral thesis at NTNU;2015:9, Doctoral thesis, 2015)The thesis empirically investigates how revenues from hydropower resources affect local governments in Norway, using methods and approaches from recent innovation in applied econometrics. It emphasizes the importance of ... -
Hydropower Scheduling Analysis Using Statistics and Stochastic Programming
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:229, Doctoral thesis, 2014)Vannkraftprodusenter med magasin har muligheten til å flytte produksjon til timer hvor prisen er gunstig. Dette øker produsentenes inntekter og bidrar til å møte samfunnsbehovet for elektrisitet. Å flytte produksjonen til ... -
Hydropower Scheduling with State-Dependent Discharge Constraints: An SDDP Approach
(Peer reviewed; Journal article, 2022)Environmental constraints in hydropower systems serve to ensure sustainable use of water resources. Through accurate treatment in hydropower scheduling, one seeks to respect such constraints in the planning phase while ... -
Hydropower‐driven thermal changes, biological responses and mitigating measures in northern river systems
(Peer reviewed; Journal article, 2021)Water temperatures control life histories and diversity of aquatic species. Hydropower regulation, particularly in high head systems, alters natural water temperature regimes, which may have profound and long-term impacts ... -

Hydrostatic Stability and Hydrodynamics of a Floating Wind Turbine Platform Integrated with Oscillating Water Columns: A Design Study
(Peer reviewed; Journal article, 2024)One of the challenges in the installation of Floating Wind Turbines (FWTs) is the occurrence of undesired resonant motions under environmental conditions, which adversely impact their lifespan, maintenance cost, components ... -
HydroStator : hovedfunn og resultater i KPN-prosjektet HydroStator
(SINTEF Rapport;, Research report, 2022)Modeller som beskriver temperatur- og frekvensavhengighet til elektriske delutladninger er utviklet og viser at tilstandskontroll med den mer praktiske VLF-metoden som benytter 0,1 Hz høyspenning er representativ for 50 ... -
Hydrotalcite Based Ni-Co Bi-metallic Catalysts for Steam Reforming of Methane
(Master thesis, 2016)Hydrotalcites or layered-double-hydroxides (LDH) are a class of nanostructured anionic clays. These compounds exhibit high surface areas, high thermal stability and uniform distribution of active metals. Different attempts ... -
