Analysis of a Costly Fiberglass-Polyester Air Filter Fire
(Journal article; Peer reviewed, 2022)In September 2020, a fire at a liquefied natural gas (LNG) plant in the Arctic areas of Norway received national attention. In an unengaged air intake, the heat exchanger designed to prevent ice damage during production ... -
Atmospheric Drivers of Wind Turbine Blade Leading Edge Erosion: Review and Recommendations for Future Research
(Journal article; Peer reviewed, 2022)Leading edge erosion (LEE) of wind turbine blades causes decreased aerodynamic performance leading to lower power production and revenue and increased operations and maintenance costs. LEE is caused primarily by materials ... -
The Consistency of Yields and Chemical Composition of HTL Bio-Oils from Lignins Produced by Different Preprocessing Technologies
(Journal article; Peer reviewed, 2022-06-27)This work evaluates the effect of feedstock type and composition on the conversion of lignin to liquid by solvolysis with formic acid as hydrogen donor (LtL), by analyzing the yields and molecular composition of the liquid ... -
Enabling Large-Scale Carbon Capture, Utilisation, and Storage (CCUS) Using Offshore Carbon Dioxide (CO2) Infrastructure Developments - A Review
(Journal article; Peer reviewed, 2019)Presently, the only offshore project for enhanced oil recovery using carbon dioxide, known as CO2-EOR, is in Brazil. Several desk studies have been undertaken, without any projects being implemented. The objective of this ... -
Energetic and Exergetic Performances of a Retrofitted, Large-Scale, Biomass-Fired CHP Coupled to a Steam-Explosion Biomass Upgrading Plant, a Biorefinery Process and a High-Temperature Heat Network
(Journal article; Peer reviewed, 2021)This paper aims at assessing the impact of retrofitting an existing, 730 MWe, coal-fired power plant into a biomass-fired combined heat and power (CHP) plant on its energetic and exergetic performances. A comprehensive ... -
Enthalpies of Hydrate Formation and Dissociation from Residual Thermodynamics
(Journal article; Peer reviewed, 2019-12-11)We have proposed a consistent thermodynamic scheme for evaluation of enthalpy changes of hydrate phase transitions based on residual thermodynamics. This entails obtaining every hydrate property such as gas hydrate ... -
Hydrate Plugging and Flow Remediation during CO2 Injection in Sediments
(Journal article; Peer reviewed, 2020)Successful geological sequestration of carbon depends strongly on reservoir seal integrity and storage capacity, including CO2 injection efficiency. Formation of solid hydrates in the near-wellbore area during CO2 injection ... -
Hydrate Production Philosophy and Thermodynamic Calculations
(Journal article; Peer reviewed, 2020)The amount of energy in the form of natural gas hydrates is huge and likely substantially more than twice the amount of worldwide conventional fossil fuel. Various ways to produce these hydrates have been proposed over the ... -
Pressure Measurements for Monitoring CO2 Foam Pilots
(Journal article; Peer reviewed, 2022)This study focuses on the use of pressure measurements to monitor the effectiveness of foam as a CO2 mobility control agent in oil-producing reservoirs. When it is applied optimally, foam has excellent potential to improve ... -
Single-Cell Tests to Explore the Reliability of Sofc Installations Operating Offshore
(Journal article; Peer reviewed, 2020)This paper studies the robustness of off-shore solid oxide fuel cell (SOFC) installations and the nature and causes of possible cell degradation in marine environments. Two important, cathode-related, impediments to ensuring ... -
Unsteady-State CO2 Foam Generation and Propagation: Laboratory and Field Insights
(Journal article; Peer reviewed, 2022-09-07)This work presents a multiscale experimental and numerical investigation of CO2 foam generation, strength, and propagation during alternating injection of surfactant solution and CO2 at reservoir conditions. Evaluations ... -
Why should we use residual thermodynamics for calculation of hydrate phase transitions?
(Journal article; Peer reviewed, 2020)The formation of natural gas hydrates during processing and transport of natural has historically been one of the motivations for research on hydrates. In recent years, there has been much focus on the use of hydrate as a ... -
Wind Energy on the High Seas: Regulatory Challenges for a Science Fiction Future
(Journal article; Peer reviewed, 2022)This paper aims to study the current regulation and governance of wind energy turbines on the high seas and detect regulatory challenges. We focus on the existing regulatory framework to develop marine wind farms in areas ...
