Integration of Degradation Processes in a Strategic Offshore Wind Farm O&M Simulation Model
(Journal article; Peer reviewed, 2017)Decision support models for offshore wind farm operation and maintenance (O&M) are required to represent the failure behavior of wind turbine components. Detailed degradation modelling is already incorporated in models for ... -
Investigating the Potential for Increased Energy Utilisation and Reduced CO2 Emissions at Mo Industrial Park
(Peer reviewed; Journal article, 2020)The potential for increased energy utilisation and reduced carbon footprint has been investigated for the industrial park Mo Industri Park (MIP), located at Mo i Rana, Norway. Process data has been gathered to quantify the ... -
Is It Possible to Supply Norwegian Apartment Blocks with 4th Generation District Heating?
(Journal article; Peer reviewed, 2019)Direct electricity is widely used for heating purposes in Norway, leading to significant strain on the electricity grid during the heating season. Conversion to 4th generation district heating (4GDH) is an effective method ... -
Liquid Hydrogen Spills on Water—Risk and Consequences of Rapid Phase Transition
(Peer reviewed; Journal article, 2021)Liquid hydrogen (LH2 ) spills share many of the characteristics of liquefied natural gas (LNG) spills. LNG spills on water sometimes result in localized vapor explosions known as rapid phase transitions (RPTs), and are a ... -
Machine-Learning-Based Prediction of HVAC-Driven Load Flexibility in Warehouses
(Peer reviewed; Journal article, 2023)This paper introduces a methodology for predicting a warehouse’s reduced load while offering flexibility. Physics-based energy simulations are first performed to model flexibility events, which involve adjusting cooling ... -
Market Manipulation in Stock and Power Markets: A Study of Indicator-Based Monitoring and Regulatory Challenges
(Peer reviewed; Journal article, 2023)In recent years, algorithmic-based market manipulation in stock and power markets has considerably increased, and it is difficult to identify all such manipulation cases. This causes serious challenges for market regulators. ... -
Medium-Term hydropower scheduling with variable head under inflow, energy and reserve capacity price uncertainty
(Journal article; Peer reviewed, 2019)We propose a model for medium-term hydropower scheduling (MTHS) with variable head and uncertainty in inflow, reserve capacity, and energy price. With an increase of intermittent energy sources in the generation mix, it ... -
Micro- and macroscale consequences of interactions between CO2 and shale rocks
(Peer reviewed; Journal article, 2020)In carbon storage activities, and in shale oil and gas extraction (SOGE) with carbon dioxide (CO2) stimulation fluid, CO2 comes into contact with shale rock and its pore fluid. As a reactive fluid, the injected CO2 displays ... -
Minimum leading edge protection application length to combat rain-induced erosion of wind turbine blades
(Peer reviewed; Journal article, 2021)Leading edge erosion (LEE) repairs of wind turbine blades (WTBs) involve infield application of leading edge protection (LEP) solutions. The industry is currently aiming to use factory based LEP coatings that can applied ... -
Modeling of a CO2‐Based Integrated Refrigeration System for Supermarkets
(Peer reviewed; Journal article, 2021)An integrated energy system that consists of a centralized refrigeration unit can deliver the entire HVAC&R (heating, ventilation, air conditioning, and refrigeration) demand for a supermarket. CO2 (R744) is a natural ... -
Modeling Water Droplet Freezing and Collision with a Solid Surface
(Peer reviewed; Journal article, 2021)Water droplets released from the sea surface represent one of the major causes of ice accretion on marine vessels. A one-dimensional model of the freezing of a spherical water droplet moving in cold air was developed. The ... -
Monitoring of Thermal and Flow Processes in the Two-Phase Spray-Ejector Condenser for Thermal Power Plant Applications
(Peer reviewed; Journal article, 2022)The paper deals with the problem of accurate measuring techniques and experimental research methods for performance evaluation of direct contact jet-type flow condensers. The nominal conditions and range of temperature, ... -
Multi-criteria studies and assessment supporting the selection of locations and technologies used in co2-egs systems
(Peer reviewed; Journal article, 2021)The paper describes application of the cross-impact method in the process of selecting locations and technologies used in a geothermal system based on energy accumulated in a dry rock formation, where CO2 is used as the ... -
Multi-Ejector Concept: A Comprehensive Review on its Latest Technological Developments
(Journal article; Peer reviewed, 2019)The adoption of the EU F-Gas Regulation 517/2014 and the resulting development of the multi-ejector concept have led carbon dioxide to take center stage as the sole refrigerant (R744) in several applications. Therefore, a ... -
Novel Control Approach for a Hybrid Grid-Forming HVDC Offshore Transmission System
(Peer reviewed; Journal article, 2020)This article describes a hybrid topology of high-voltage direct current (HVDC) for offshore wind farms using a series connection of a voltage source converter (VSC) and six-pulse diode rectifier (6P-DR). In this topology, ... -
On the effect of co2 on seismic and ultrasonic properties: A novel shale experiment
(Peer reviewed; Journal article, 2021)Carbon capture and storage (CCS) by geological sequestration comprises a permeable formation (reservoir) for CO2 storage topped by an impermeable formation (caprock). Time-lapse (4D) seismic is used to map CO2 movement in ... -
