Efficiency of Pressurized Rock Traps for Unlined Hydropower Tunnels
(Peer reviewed; Journal article, 2021)Pressurized rock traps are constructed in many hydropower plants to stop sand and gravel from being transported through the turbines. Pressurized rock traps are typically located in the downstream end of unlined headrace ... -
Efficient Production of Clean Power and Hydrogen Through Synergistic Integration of Chemical Looping Combustion and Reforming
(Peer reviewed; Journal article, 2020)Chemical looping combustion (CLC) technology generates power while capturing CO2 inherently with no direct energy penalty. However, previous studies have shown significant energy penalties due to low turbine inlet temperature ... -
Electrodialytic Energy Storage System: Permselectivity, Stack Measurements and Life-Cycle Analysis
(Peer reviewed; Journal article, 2020)Reverse electrodialysis and electrodialysis can be combined into a closed energy storage system, allowing for storing surplus energy through a salinity difference between two solutions. A closed system benefits from simple ... -
Energy Pathways for Future Norwegian Residential Building Areas
(Peer reviewed; Journal article, 2021)Owing to stricter building energy requirements, future buildings will be characterized by low base loads and occasional high peaks. However, future building areas will still contain existing and historical buildings with ... -
Enhancing oil recovery with hydrophilic polymer-coated silica nanoparticles.
(Peer reviewed; Journal article, 2020)Nanoparticles (NPs) have been proposed for enhanced oil recovery (EOR). The research has demonstrated marvelous effort to realize the mechanisms of nanoparticles EOR. Nevertheless, gaps still exist in terms of understanding ... -
Evaluation Method for the Hourly Average CO2eq. Intensity of the Electricity Mix and Its Application to the Demand Response of Residential Heating
(Journal article; Peer reviewed, 2019)This work introduces a generic methodology to determine the hourly average CO2eq. intensity of the electricity mix of a bidding zone. The proposed method is based on the logic of input–output models and avails the balance ... -
Evaluation of Integrated Concepts with CO2 for Heating, Cooling and Hot Water Production
(Journal article; Peer reviewed, 2021)The hotel sector is characterized by high thermal demands and a large carbon footprint, which greatly contributes to the global warming effect. Consequently, there is a need to investigate solutions that can reduce energy ... -
Evaluation of the Effects of Coal Jigging by Means of Kruskal–Wallis and Friedman Tests
(Peer reviewed; Journal article, 2023)Coal beneficiation processes are often based on gravitational enrichment techniques. Therefore, various types of jigs are often used in this area. A number of factors determine the quality of the final product. Therefore, ... -
Evaluation on Overheating Risk of a Typical Norwegian Residential Building under Future Extreme Weather Conditions
(Journal article; Peer reviewed, 2020)As the temperature in the summer period in Norway has been always moderate, little study on the indoor comfort of typical Norwegian residential buildings in summer seasons can be found. Heat waves have attacked Norway in ... -
