Prospective Environmental Impacts of Selected Low-Carbon Electricity Technologies
(Doctoral thesis at NTNU;2015:312, Doctoral thesis, 2015)Abstract: As one of the main contributors to greenhouse gas (GHG) emissions, the global electricity production sector faces the challenge of mitigating its emissions by transitioning towards cleaner production technologies. ... -
Prospective Life Cycle Assessment of Container Shipping
(Master thesis, 2017)International shipping has lower direct CO2 emissions per unit of mass transported than any other transportation mode. However, the sector s absolute direct emissions in 2012 totalled 815 million tonnes CO2-equivalents, ... -
Prospects of using equilibrium-based column models in dynamic process simulation of post-combustion CO2 capture for coal-fired power plant
(Journal article; Peer reviewed, 2017)This paper discusses the limitations and prospects of using equilibrium-based column models for the dynamic simulation of post-combustion CO2 capture processes. Based on their features, one of three available commercial ... -
Protein kinase C activation mediates interferon-β-induced neuronal excitability changes in neocortical pyramidal neurons
(Journal article; Peer reviewed, 2014)Background Cytokines are key players in the interactions of the immune and nervous systems. Recently, we showed that such interplay is mediated by type I interferons (IFNs), which elevate the excitability of neocortical ... -
Pump as Turbine - Symmetry Prediction Method for Pump as Turbine Characteristics
(Master thesis, 2018)As a cheap and available source of renewable energy, regular centrifugal pumps may be run in reverse to act as hydro turbines. Pumps as turbines (PAT) are especially relevant for isolated rural areas, or in developing ... -

Pump turbines in existing powerplants
(Master thesis, 2019)En brukervennlig metode for å designe kontraroterende aksialpumper har blitt utviklet ved bruk av Matlab. Grafiske brukergrensesnitt har blitt laget for å skrive inn designparametre og å vise designresultater. Designmetoden ... -
Pump-Turbines in Conventional Hydropower Plants
(Peer reviewed; Journal article, 2021)This paper proposes an innovative approach to retrofit existing hydropower plants with suitable upper and lower reservoirs into pumped storage. The conventional methods are both comprehensive and expensive, mainly due to ... -
Pumpekraftverk for effektproduksjon
(Master thesis, 2008)Europa har et stadig økende energiforbruk, og har samtidig mål om å redusere bruken av fossile brensel. De termiske kraftverkene er trege å regulere, og et økende innslag av vindkraft forsterker en allerede vanskelig ... -
PV Systems on Refrigerated Warehouses
(Bachelor thesis, 2021)Despite recent years of rapid development, PV power constitutes for only 0.4 % of the total installed capacity of power production in Norway, making this an area with huge potential for expansion. Finding suitable areas ... -
PV-to-Heat: Control and Monitoring Methods
(Master thesis, 2024)Mange afrikanske land har en økende befolkning og økonomi. Imidlertid er energiproduksjonen regelmessig ikke tilstrekkelig, noe som fører til strømbrudd i byene og distriktene har ikke tilgang til strøm. Mindre enn 10 % ... -
PVTx Modeling of CO2 Pipeline at Depressurization Conditions Using SPUNG Equation of State (EoS) with a Comparison to SRK
(Journal article; Peer reviewed, 2014)The proper modeling of CO2 depressurization is very important for the design for safety of a pipeline. One key element of the modeling process is the thermodynamics and transport properties modeling. In this work, an ... -
