Performance mapping of the R744 ejectors for refrigeration and air conditioning supermarket application: A hybrid reduced-order model
(Journal article; Peer reviewed, 2018)The continuous derivation of the ambient temperature and cooling demand in CO2 refrigeration and air-conditioning systems equipped with multi-ejector modules for supermarkets requires the analysis of the fixed ejector ... -
Process modeling and optimization for torrefaction of forest residues
(Journal article; Peer reviewed, 2017)This work aims to build a comprehensive biomass torrefaction model, which can provide a wide range of information essential for industrialization and commercialization of the process. Norwegian forest residue (birch branches) ... -
Scenarios for carbon capture integration in a waste-to-energy plant
(Peer reviewed; Journal article, 2021)In this work, the performance of an amine-based post-combustion carbon capture system using MEA (monoethanolamine) integrated to a Waste-to-Energy (WtE) plant is studied. WtE plants are affected by fluctuations at different ... -
Splitting measurements of the total heat demand in a hotel into domestic hot water and space heating heat use
(Peer reviewed; Journal article, 2020)To achieve more efficient energy use in buildings, space heating (SH) and domestic hot water (DHW) heat use should be analysed separately. Unfortunately, in many buildings, the heat meters measure the total heat use only, ... -
Stochastic electricity dispatch: A challenge for market design
(Peer reviewed; Journal article, 2018)We consider an energy-only electricity market where some generation and/or load is uncertain, and where there are flexibility costs, i.e. some conventional power plants have to be scheduled well before real time in order ... -
Stochastic energy market equilibrium modeling with multiple agents
(Journal article; Peer reviewed, 2017)The energy markets are characterized by many agents simultaneously solving decision problems under uncertainty. It is argued that Monte Carlo simulations are not an adequate way to assess behavioral uncertainty; one should ... -
System impact of heat exchanger pressure loss in ORCs for smelter off-gas waste heat recovery
(Peer reviewed; Journal article, 2021)Applying Rankine cycles to smelter off-gas could increase the required off-gas fan power in an order of magnitude equivalent to the power production. Predicting the fan power is not straightforward since it is affected in ... -
System model derivation of the CO2 two-phase ejector based on the CFD-based reduced-order model
(Journal article; Peer reviewed, 2018)The developed reduced-order model (ROM) of the R744 two-phase ejector was presented in this paper. The proper orthogonal decomposition (POD) model was employed together with the radial basis function (RBF) to evaluate the ... -
System-friendly process design: Optimizing blue hydrogen production for future energy systems
(Peer reviewed; Journal article, 2022)While the effects of ongoing cost reductions in renewables, batteries, and electrolyzers on future energy systems have been extensively investigated, the effects of significant advances in CO2 capture and storage (CCS) ... -
The impact of Zero Energy Buildings on the Scandinavian energy system
(Journal article; Peer reviewed, 2017)This paper investigates how an extensive implementation of net Zero Energy Buildings (ZEBs) affects cost-optimal investments in the Scandinavian energy system towards 2050. Analyses are done by a stochastic TIMES model ... -
Thermal energy storage sizing for industrial waste-heat utilization in district heating: A model predictive control approach
(Peer reviewed; Journal article, 2021)Thermal energy storage (TES) is a key technology for enabling increased utilization of industrial waste heat in district heating. The ability of TES to equalize offsets in demand and supply depends strongly on the sizing, ... -

Ultrasound intensified CO2 desorption from pressurized loaded monoethanolamine solutions. I. parameters investigation and modelling
(Peer reviewed; Journal article, 2018)CO2 stripping from loaded monoethanolamine (MEA) aqueous solutions intensified by means of ultrasound was investigated in a lab-scale kettle reboiler with both gas and liquid continuous operations. The reboiler operating ... -
Ultrasound intensify CO2 desorption from pressurized loaded monoethanolamine solutions. II. Optimization and cost estimation
(Journal article; Peer reviewed, 2019) -
Waste-to-energy technology integrated with carbon capture – Challenges and opportunities
(Peer reviewed; Journal article, 2020)Carbon dioxide emission is a serious environmental issue that humankind must face soon. One of the promising technologies for reducing global CO2 emissions is oxy-fuel combustion (OFC) technology, which belongs to the ... -
Work and Heat Integration: An emerging research area
(Journal article; Peer reviewed, 2018)The extension from Heat Integration (HI) and design of Heat Exchanger Networks (HENs) to including heating and cooling effects from pressure changing equipment has been referred to as Work and Heat Integration and design ... -
