Systematic review: Upscaling energy retrofitting to the multi-building level
(Journal article; Peer reviewed, 2024)Retrofitting the building stock is pivotal to achieving climate neutrality by 2050. Most of the existing research on energy efficiency focuses on new residential buildings. The focus must shift to multi-building retrofits, ... -
Human factor influences on supervisory control of remotely operated and autonomous vessels
(Journal article; Peer reviewed, 2024)Autonomous ships require remote supervision from a human operator to ensure safety. However, there are knowledge gaps concerning human factor influences on remote supervisory control. We investigate the influence of five ... -
Energy efficient and climate friendly refrigeration systems onboard fishing vessels
(Chapter, 2023)Refrigeration systems onboard fishing vessels are necessary to keep the catch at a low temperature and to ensure long shelf life. Most refrigeration systems in the world fishing fleet still have R-22 as a working fluid, ... -
Integration of Cold Thermal Energy Storage at a Pelagic Fish Processing Plant: A Modelling Approach
(Chapter, 2023)Energy intensive sectors such as food processing are paying more and more attention towards energy conservation and reducing their total carbon footprint. The energy demand of a pelagic fish processing plant has been ... -
Integrated CO2 refrigeration and heat pump system for a dairy plant: Energy analysis and potential for cold thermal energy storage
(Chapter, 2023)Dairy processing is considered very energy-intensive due to significant thermal demands for both cooling and heating at different temperature levels. Conventional dairy plants have separate systems for supplying the various ... -
Study on retaining natural refrigerant in seafood processing industries in India
(Chapter, 2023)In the seafood processing sector in India, natural refrigerant such as NH3 is currently replaced by Freon refrigerants such as HFC-404A, because these systems are comparably more compact, operate above atmospheric pressure ... -
Sustainable production of fish protein hydrolysates: overall system architecture and footprint
(Chapter, 2023)In this research work, the most efficient and energy-saving techniques for fish protein hydrolysates production were investigated from cradle-to-gate, in terms of overall cooling, heating, and energy demands. Advanced ... -
Fully nonlinear phase-resolved wave modelling in the Norwegian fjords for floating bridges along the E39 coastal highway
(Journal article; Peer reviewed, 2023)Coastal wave conditions are highly influenced by bathymetry variations and coastlines. The Norwegian fjords present large gradients of bathymetry changes and irregular coastline geometries that make the understanding of ... -
Numerical investigation of an ammonia-water absorption-compression high-temperature heat pump for hot water and steam production in food processing
(Chapter, 2023)To achieve climate neutrality in the food sector, there is an urgent need for eco-friendly steam boilers. The absorption-compression heat pumps (ACHP) using an ammonia-water mixture as working fluid can provide a high heat ... -
Tunnelbyggetid 2021 - testet i et komplekst tunnelprosjekt
(Master thesis, 2023)I anleggsbransjen har det oppstått usikkerhet, konflikter og til dels tvister omkring byggetiden til samferdselstunneler de siste tiårene. For å redusere uenighetene har entreprenørforeningen for Bygg og Anlegg, sammen med ... -
Effect factors for marine invasion impacts on biodiversity
(Journal article; Peer reviewed, 2024)Purpose Marine vertebrate populations have halved in the past decades, and invasive species are a major driver for this loss. While many model the spread of invasive species, a model to assess impacts of marine invasions, ... -
Hydrodynamic rainfall-runoff modelling for flash floods in small and steep catchments
(Doctoral theses at NTNU;2024:261, Doctoral thesis, 2024)Global warming and climate change lead to more frequent and extreme weather events. These include sudden and intense rainfall and rising temperatures which cause flash floods. In steep terrains, flash floods with high-flow ... -

Limits to graphite supply in a transition to a post-fossil society
(Peer reviewed; Journal article, 2024)Transitioning to electric vehicles (EVs) powered by lithium-ion batteries (LIBs) aims at reducing emissions in the transportation sector, thereby decreasing fuel oil use and crude oil extraction. Yet, synthetic graphite, ... -
Stability Challenges and Remedial Practices in Himalayan Hydropower Tunnels – A Review
(Journal article; Peer reviewed, 2024)The instability in tunnels is mainly affected by geological anomalies, rock mass quality, complex geological structures, active tectonics, and stress anisotropy. This review article presents challenges associated with ... -
A Novel Method for Anomaly Detection and Signal Calibration in Water Quality Monitoring of an Urban Water Supply System
(Peer reviewed; Journal article, 2024)Water quality monitoring plays a crucial role in urban water supply systems for the production of safe drinking water. However, the traditional approach to water monitoring in Norway relies on a periodic (weekly/biweekly/monthly) ... -
