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 ... -
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. ... -
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 ... -
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 ... -
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 ... -
Operating Hydrogen-Based Energy Storage Systems in Wind Farms for Smooth Power Injection: A Penalty Fees Aware Model Predictive Control
(Peer reviewed; Journal article, 2022)Smooth power injection is one of the possible services that modern wind farms could provide in the not-so-far future, for which energy storage is required. Indeed, this is one among the three possible operations identified ... -
Parametric Design to Maximize Solar Irradiation and Minimize the Embodied GHG Emissions for a ZEB in Nordic and Mediterranean Climate Zones
(Peer reviewed; Journal article, 2020)This work presents a validated workflow based on an algorithm developed in Grasshopper to parametrically control the building’s shape, by maximizing the solar irradiation incident on the building envelope and minimizing ... -
Platinum and Platinum Group Metal-Free Catalysts for Anion Exchange Membrane Fuel Cells
(Peer reviewed; Journal article, 2020)The development of active hydrogen oxidation reaction (HOR) and oxygen reduction reaction (ORR) catalysts for use in anion exchange membrane fuel cells (AEMFCs), which are free from platinum group metals (PGMs), is expected ... -
Polymer Gels Made with Functionalized Organo-Silica Nanomaterials for Conformance Control.
(Journal article; Peer reviewed, 2019)Deep placement of gel in waterflooded hydrocarbon reservoirs may block channels with high water flow and may divert the water into other parts of the reservoir, resulting in higher oil production. In order to get the gel ... -
The Potential of Chemically Recuperated Power Cycles in Markets with High Shares of Variable Renewables
(Peer reviewed; Journal article, 2023)Rising shares of variable wind and solar generation in decarbonized electricity systems motivate the development of novel power cycles employing unconventional fuels. Innovative designs must be highly flexible and profitable ... -
Short-Range Structure of Ti0.63V0.27Fe0.10D1.73 from Neutron Total Scattering and Reverse Monte Carlo Modelling
(Peer reviewed; Journal article, 2020)Ti-V-based body-centered cubic (BCC) alloys have potential for large-scale hydrogen storage if expensive vanadium is substituted with much cheaper Fe-containing ferrovanadium. Use of ferrovanadium reduces the alloys’ ... -
Simulation of stress hysteresis effect on permeability increase risk along a fault
(Journal article; Peer reviewed, 2019)CO2 sequestration projects will in the coming years include both aquifer and depleted oil and gas field sites, with different stress paths and history. Stress changes and stress concentration effects on faults will have ... -
