Foredraget beskriver nedbrytningsmekanismene og de relevante materialparametrene når alkalireaksjoner og frost opptrer hver for seg generelt og med spesiell vekt på relevans for betongdammer: betydning av tilstrekkelig mengde alkalier, fukt og reaktivt tilslag for alkalireaksjoner, og høy nok...

The use of battery energy storage systems (BESS) based on Lithium-Ion Batteries (LIBs) in buildings is increasing, as being part of the solution for a reducing greenhouse gas emission. The main usage areas for a BESS are to store electric energy obtained from solar panels, or to serve as a back-up...

This memo provides an update on the logistics of the hydrogen industry in Northern Europe, building upon our 2024 analysis. We present recent advancements in hydrogen production, transport, and storage technologies, with a focus on Norway and other key countries in the region. We discuss new...

Offshore mooring chains are critical components for floating structures such as oil platforms and wind turbines, yet they face degradation from corrosion, fouling, and mechanical wear. Current inspection methods are limited, often relying on manual measurements of single links, which lack...

This project, funded by Handelens Miljøfond with support from industry partners and a sling producer, explored how synthetic lifting slings used in Norwegian construction can shift from single-use disposal toward circular practices. Although technically durable and recyclable, most slings are...

This paper presents experimental validation of a time-domain load parameter determination method for single-phase circuits using a state-of-the-art smart grid laboratory equipped with power hardware and real-time emulators. The proposed method identifies circuit parameters using only instantaneous...

This paper describes challenges and possibilities related to operation and control of hybrid AC/DC power transmission grids. The aim is to discuss topics that transmission system operators and regulators must assess in order to develop technical standards, grid codes, market regulations and...

This report focuses on geomagnetically induced currents (GIC) that can be induced in long subsea power cables. Literature indicates that the water depth itself, in which the cable will be laid, will not contribute to an attenuation of the geoelectric field for those water depths relevant for the...

Many studies have evaluated biomass behavior in a gasification process. Similar studies with torrefied biomass are needed to evaluate the improvements in biomass properties with torrefaction. This forms the basis of this study. A two-stage biomass gasification model is presented by using Aspen Plus...
