...neutrality of the global trucking, shipping and aviation sectors by 2050 could be achieved by substituting fossil fuels with renewable hydrogen and synthetic fuels. To investigate the economic impact of fuel substitution over time, a holistic cost model is developed and applied to three case studies in Norway...

In future power systems, wind power plants are supposed to contribute in the voltage and frequency stability of the grid. For this purpose, the control strategy of the wind power-frequency converter system needs to change from grid-following to grid-forming control. In this paper, the influence of future...

...heat and power production. The novelty of the work lays in that (i) it provides an analysis of the transient performance of biomass-based fluidized bed combustion plants for combined heat and power production, (ii) the dynamic model includes a description of both the gas and water-steam sides and (iii)...

...wind integration studies in the United States and Europe. Transmission planning for energy resources is different from planning for capacity resources. Those differences are explained, and illustrated with examples from several regions of the United States and Europe. Transmission planning for wind is becoming...

...e. Na, K, Pb, Zn, Cl and S) are investigated for three biomasses (wood, demolition wood and coffee waste) and six mixtures of these as pellets both with and without air staging in a laboratory reactor. In order to get a complete overview of the combustion products, both online and offline analytical methods...

...breakdown of liquid and solid insulation. This is important, as the electric power grid depends on reliable and cost effective insulation materials. Prebreakdown phenomena in liquid and solid neat cyclohexane, neat n-tridecane, n-tridecane with 0.1 M N,N-dimethylaniline (DMA) and ntridecane with 0.1...

...both when they are undesired and can impair processes operation, and when strict control is required in fields such as food technology, the pharmaceutical industry and cryogenic CO₂ capture. We present experimental results and theoretical predictions for the solid-formation and melting temperatures of ice...

Negative emissions and Carbon Dioxide Removal (CDR) at scale is required to offset hard to reduce emission streams and remove historic emissions from the atmosphere. CDR relies on and intervenes with the basics of earth systems such as the ocean, land, soil, and the atmosphere. This implies that...

...demand for optimized utilization will be increasing with respect to efficiency, aesthetics and reliability. In cold climate regions, we predict that there will also be a growing focus on how to avoid snow and ice formation on the exterior surfaces of BIPV. During the winter period there is substantially...

...hexamethyldisiloxane and TEOS: tetraethylorthosilicate) have been fabricated in a two-step process using atmospheric pressure plasma-enhanced chemical vapor deposition (AP-PECVD) on ethylene-propylene-diene terpolymer (EPDM) and NBR (nitrile butadiene rubber) to reduce stick slip and wear of the elastomer...

...work, Norway spruce stem wood, stump and bark were torrefied in a bench scale tubular reactor at 225, 275 and 300 °C with two residence times (30 and 60 min). Effect of torrefaction on general properties, chemical composition, grindability and microstructure and morphology of biomass samples were studied...

...heating system has been investigated employing simulations from the IDA Indoor Climate and Energy software. For the construction of the original building, customs and regulations from the period 1981-90 were employed, and the building envelope was upgraded to the requirements of the Norwegian research centre...
