Energy assessments of onboard CO2 capture from ship engines by MEA-based post combustion capture system with flue gas heat integration
(Peer reviewed; Journal article, 2022)An early phase feasibility study was carried out for offshore CO2 capture from ship engines of a CO2 transport ship. A flexible in-house process simulator was applied in the assessments. Parametric studies of the overall ... -
Energy conservation and coupling error reduction in non-iterative co-simulations
(Journal article; Peer reviewed, 2019)When simulators are energetically coupled in a co-simulation, coupling errors alter the total energy of the full system. This distorts system dynamics, lowers the quality of the results, and can lead to instability. Using ... -
Energy conservation and power bonds in co-simulations: non-iterative adaptive step size control and error estimation
(Journal article; Peer reviewed, 2017-07)Here, we study the flow of energy between coupled simulators in a co-simulation environment using the concept of power bonds. We introduce energy residuals which are a direct expression of the coupling errors and, hence, ... -
Energy consumption and environmental impact of buildings. Case study of traditional and modern wooden buildings
(Prosjektrapport (Norges Byggforskningsinstitutt);177, Research report, 1995) -
Energy consumption for domestic hot water use in Norwegian hotels and nursing homes
(Journal article; Peer reviewed, 2019)Domestic Hot Water (DHW) production constitutes a significant proportion of the energy demand of modern buildings, and as the building envelope is improved the share increases. This article discusses the results from a ... -
Energy consumption of ammonia refrigeration system on board a fishing vessel
(Sciences et technique du froid;, Chapter; Peer reviewed, 2021)When assessing the carbon footprint of seafood from capture fisheries, the fuel use during fishing operation is the major contributor to overall greenhouse gas emissions. While the necessary shift towards low-carbon fuels ... -
Energy Distribution in HC FeMn and SiMn - Energy vs Exergy Analyses
(Journal article; Peer reviewed, 2019)The metal producing industry is a high consumer of energy and large amounts of excess heat are produced. Increasing the energy efficiency would be beneficial, both in terms of the environment and also from an economical ... -

Energy efficiency and district heating to reduce future power shortage. Potential scenarios for Norwegian building mass towards 2050
(ZEN Report;47, Research report, 2023)Energy efficiency, district heating and heat pumps for reduced power consumption The Norwegian power system is facing enormous challenges in the transition to a fossil-free society. The on-going electrification of transport ... -
Energy Efficiency Increase by Improved Operation and Control in Wood Stoves
(Peer reviewed; Journal article, 2023)The purpose and novelty of this work was to evaluate both the total and the transient energy efficiency of three types of modern wood stoves based on experimental results at different loads and elaborate on the level of ... -
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, ... -
