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 ... -
CO2 Pipeline Integrity: Comparison of a Coupled Fluid-structure Model and Uncoupled Two-curve Methods
(Peer reviewed; Journal article, 2014)One challenge in CCS is related to the prevention of running-ductile fracture in CO2-carrying pipelines. Commonly used tools for ensuring crack arrest in pipelines hinge mainly on semi-empirical models, which may not be ... -
CO2 removal at high temperature from multi-component gas stream using porous ceramic membranes infiltrated with molten carbonates
(Peer reviewed; Journal article, 2013)This work reports on the investigation of CO2 selective membranes for pre-combustion and post- combustion processes, in which CO2 is extracted from multi-component gas streams at intermediate temperature (400 – 600 °C). ... -

Co2 Separation in Nanocomposite Membranes by the Addition of Amidine and Lactamide Functionalized POSS® Nanoparticles into a PVA Layer
(Peer reviewed; Journal article, 2018)In this article, we studied two different types of polyhedral oligomeric silsesquioxanes (POSS®) functionalized nanoparticles as additives for nanocomposite membranes for CO2 separation. One with amidine functionalization ... -
Cohesive zone modelling of hydrogen induced cracking on the interface of clad steel pipes
(Peer reviewed; Journal article, 2017)A coupled finite element hydrogen diffusion and cohesive zone modelling approach has been applied to simulate hydrogen induced fracture initiation in a hot rolled bonded clad steel pipe. The results are compared to ... -
Cold Sintering as a Cost-Effective Process to Manufacture Porous Zinc Electrodes for Rechargeable Zinc-Air Batteries
(Peer reviewed; Journal article, 2020)Zinc-air batteries (ZABs) offer a sustainable and safe pathway to low-cost energy storage. Recent research shows that thermally-sintered porous Zn electrodes with a three-dimensional network structure can enhance the ... -
Collaborative optimization by shared objective function data
(Peer reviewed; Journal article, 2022)This article presents a collaborative algorithmic framework that is effective for solving a multi-task optimization scenario where the evaluation of their objectives consists of two parts: The first part involves a common ... -
Collection, Thermal Treatment, and Remelting End-of-Life Al Packaging in Norway
(Peer reviewed; Journal article, 2023)Aluminium (Al) is used in packaging due to its density, strength, and preservative qualities. The Norwegian packaging flows in 2020 are shown. The paper outlines a laboratory methodology to evaluate the recycling performance ... -
Coloured Building Integrated Photovoltaics: Influence on Energy Efficiency
(Journal article; Peer reviewed, 2019)Building integrated photovoltaics (BIPV) has attracted increased commercial interest in recent years due to a growing focus on efficient utilization of land area and local renewable energy generation. Aesthetic aspects ... -
Combined analytical strategies for chemical and physical characterization of tar from torrefaction of olive stone
