A future energy chain based on liquefied hydrogen
(Lecture, 2009)In the efforts to curb emissions of greenhouse gases and local pollution hydrogen has the potential of becoming a prominent energy carrier in the future energy supply, for both automotive and stationary use. Today ... -
A gas ejector for CO2 supercritical cycles
(Journal article; Peer reviewed, 2018)he CO2 ejectors are recently often used as the main expansion device in the modern refrigeration cycles. On the other hand, according to the newest literature the implementation the ejectors into supercritical CO2 power ... -
A generic framework for power system flexibility analysis using cooperative game theory
(Journal article; Peer reviewed, 2017)Electricity grid infrastructures provides valuable flexibility in power systems with high shares of variable supply due to its ability to distribute low-cost supply to load centers (spatial), in addition to interlinking a ... -
A harmonic pressure differential wave energy converter
(Journal article; Peer reviewed, 2017)A pressure differential sea wave energy converter concept using the forced harmonic motion of a hydraulic water column and hydraulic piston is presented. The mechanical power from the hydraulic piston is converted to ... -
A linear State-Space Model of an Offshore Wind Turbine, Implemented in the STAS Wind Power Plant Analysis Program
(SINTEF Energi. Rapport;TR A7474, Research report, 2015)A set of MATlab/Octave scripts have been developed, which output state matrices describing the linearized aerolastic dynamics of an offshore wind turbine. The aerodynamic model is based on momentum balance,and includes ... -
A method for simulating two-phase pipe flow with real equations of state
(Journal article; Peer reviewed, 2014)Common two-fluid models for pipe flow assume local non-equilibrium regarding phase transfer. To solve the two-fluid models together with accurate equations of state for real fluids will in most cases require mechanical, ... -
A mobile application for on-site risk based decision support
(CIRED Conference Proceedings;2017, Chapter; Peer reviewed, 2017)Maintenance and renewal decisions are essential parts of distribution system asset management as means to control cost, performance and risk. This paper reports on the development of a mobile application used for in-the-field ... -

A modified homogeneous relaxation model for CO2 two-phase flow in vapour ejector
(Journal article; Peer reviewed, 2016)In this study, the homogenous relaxation model (HRM) for CO2 flow in a two-phase ejector was modified in order to increase the accuracy of the numerical simulations The two- phase flow model was implemented on the effective ... -
A new approach to the identification of high-potential materials for cost-efficient membrane-based post-combustion CO2 capture
(Journal article; Peer reviewed, 2018)Developing “good” membrane modules and materials is a key step towards reducing the cost of membrane-based CO2 capture. While this is traditionally being done through incremental development of existing and new materials, ... -
