CO2 pipeline integrity: A coupled fluid-structure model using a reference equation of state for CO2
(Peer reviewed; Journal article, 2013)We present a coupled fluid-structure model to study crack propagation and crack arrest in pipelines. Numerical calculations of crack arrest, crack velocity and pressure profiles have been performed for steel pipes with an ... -
CO2 pipeline integrity: A new evaluation methodology
(Peer reviewed; Journal article, 2011)A coupled fluid-structure model for pipeline integrity simulations has been developed. The pipe material and fracture propagation have been modelled using the finite-element method with a local fracture criterion. The ... -
Innovation in a heterogeneous CCS research centre, managerial and organizational challenges
(Peer reviewed; Journal article, 2012)Recently, the Norwegian authorities have established a number of Centres for Environment-friendly Energy Research (CEER), intended to develop new knowledge, foster breakthrough technology and promote innovation in order ... -
An exponential time-differencing method for monotonic relaxation systems
(Peer reviewed; Journal article, 2014)We present first and second-order accurate exponential time differencing methods for a special class of stiff ODEs, denoted as monotonic relaxation ODEs. Some desirable accuracy and robustness properties of our methods are ... -
Apparatus for loss measurements under multidirectional and dc-bias flux in electrical steel laminations
(Peer reviewed; Journal article, 2020)Conventional standardized power loss measurements for electric steels are performed at flux densities with a single sinusoidal and unidirectional excitation. However, the flux inside electrical steel laminations can deviate ... -
Internal pressures and pressure gradients in mass-impregnated HVDC cables during current cycling
(Peer reviewed; Journal article, 2020)The internal pressures in the insulation of two 5-m long pieces of a state-of-the art mass-impregnated non-draining subsea cable have been measured under load current cycling at ambient temperatures ranging from 3 to 37 ... -
Framework and methodology for active distribution grid planning in Norway
(Chapter, 2020)The long-term planning frameworks currently used by electricity distribution grid companies are not designed to account for new challenges such as variable distributed generation or for new opportunities of active grid ... -
Potential of Thermal Energy Storage for a District Heating System Utilizing Industrial Waste Heat
(Peer reviewed; Journal article, 2020)The potential for utilizing industrial waste heat for district heating is enormous. There is, however, often a temporal mismatch between the waste heat availability and the heating demand, and typically fossil-based peak ... -
Nonconvex Environmental Constraints in Hydropower Scheduling
(Chapter, 2020)Environmental constraints in hydropower systems serve to ensure sustainable use of water resources. Through accurate treatment in hydropower scheduling, one seeks to respect such constraints in the planning phase while ... -
Data set for power system reliability analysis using a four-area test network
(Peer reviewed; Journal article, 2020)This article presents a test data set combining data relevant for power system reliability analysis, including network data, reliability data, basic interruption cost data, and exemplary operating state data. The data set ... -
Work Exchange Networks (WENs) and Work and Heat Exchange Networks (WHENs): A review of the current state of the art
(Peer reviewed; Journal article, 2020)This paper provides a current state-of-the-art review of literature on work exchange networks (WENs) and work and heat exchange networks (WHENs). Heat exchange networks (HENs) and mass exchange networks (MENs) have been ... -
Dissecting the exergy balance of a hydrogen liquefier: Analysis of a scaled-up claude hydrogen liquefier with mixed refrigerant pre-cooling
(Peer reviewed; Journal article, 2020)For liquid hydrogen (LH2) to become an energy carrier in energy commodity markets at scales comparable to for instance LNG, liquefier capacities must be scaled up several orders of magnitude. While state-of-the-art liquefiers ... -
Effects of scaling laws on the combustion and NOx characteristics of hydrogen burners
(Peer reviewed; Journal article, 2020)This paper proposes a novel bidirectional linkage between a long-term energy system model and an operational power market model. This combined modelling framework provides long-term energy system investment strategies that ... -
Non-linear charge-based battery storage optimization model with bi-variate cubic spline constraints
(Peer reviewed; Journal article, 2020)Variable renewable generation demands increasing amount of flexible resources to balance the electric power system, and batteries stand out as a promising alternative. Battery models for optimization typically represent ... -
Drag force for a burning particle
(Peer reviewed; Journal article, 2020)Fully-resolved simulations of a burning char particle are performed to understand the effects of chemical reastions on the drag force by using the ghost cell immersed boundary method. The momentum, heat and mass transfers ... -
Can Energy Depletion of Wild Atlantic Salmon Kelts Negotiating Hydropower Facilities Lead to Reduced Survival?
(Peer reviewed; Journal article, 2020)Repeat spawners constitute an important component of Atlantic salmon populations, but survival of post-spawning individuals (kelts) are often compromised by anthropogenic structures such as hydropower plants (HPPs). Potential ... -
Demand-side management for reducing peak-heating costs in a local low-temperature district-heating grid with waste-heat utilization
(Lecture, 2020)Low-temperature district heating (LTDH) grids extend the options for using local low-grade waste-heat sources. Such sources may exhibit a high variability in available heat and temperature level. This is the case for a ...
