High flexibility in Francis turbine operation and design philosophy: A review
(Peer reviewed; Journal article, 2022)This paper examines and discusses how various operation schemes and design philosophies can prolong the expected lifetime of a hydro turbine subjected to many start-stop cycles and high ramping rates. With the proliferation ... -
High temperature gasification of high heating-rate chars using a flat-flame reactor
(Journal article; Peer reviewed, 2018)The increasing interest in gasification and oxy-fuel combustion of biomass has heightened the need for a detailed understanding of char gasification in industrially relevant environments (i.e., high temperature and ... -
High temperature industrial heat pumps utilising natural working fluids
(Actes du ... Congres international du froid;ICR2019, Chapter; Peer reviewed, 2019)There is a large demand for heat typically in the temperature range 100-200⁰C in different industries. This is today often covered by fossil fuel burning or direct use of electricity. Heat pumps has to a lesser extent been ... -
High-Frequency Resonant Overvoltages in Transformer Regulating Winding Caused by Ground Fault Initiation on Feeding Cable
(Journal article; Peer reviewed, 2018)Transformer terminal equivalents obtained via admittance measurements are suitable for simulating high-frequency transient interaction between the transformer and the network. This paper augments the terminal equivalent ... -
High-Power Machines and Starter-Generator Topologies for More Electric Aircraft: A Technology Outlook
(Peer reviewed; Journal article, 2020)More electric aircraft (MEA) architectures consist of several subsystems, which must all comply with the settled safety requirements of aerospace applications. Thus, achieving reliability and fault-tolerance represents the ... -
High-purity H2 production with CO2 capture based on coal gasification
(Journal article; Peer reviewed, 2015)A novel hybrid concept is proposed, combining Pd-alloy membrane and low temperature separation technology, to produce pure H2 from gasified coal and capture the main part of the generated CO2. 75% of the H2 produced from ... -
High-temperature heat pumps based on natural working fluids to produce district heating from industrial waste heat.
(Science et technique du froid;2017-2, Chapter; Peer reviewed, 2017)The amount of industrial waste heat produced in Europe annually corresponds to the total annual heating demand in buildings. Common barriers for utilizing this heat are the lack of required infrastructure, i.e. a district ... -
Highlights and Lessons from the EU CCS Demonstration Project Network
(Journal article; Peer reviewed, 2017)The European Carbon Capture and Storage (CCS) Demonstration Project Network (the “Network”) is currently composed of projects located in the Netherlands, Norway, Spain, and the UK. The goal of the Network is to accelerate ... -

HLLC-type methods for compressible two-phase flow in ducts with discontinuous area changes
(Peer reviewed; Journal article, 2021)In this work, the Harten-Lax-van Leer Contact (HLLC) approximate Riemann solver is extended to two-phase flow through ducts with discontinuous cross-sections. Two main strategies are explored regarding the treatment of the ... -
Household customers' assessment to capacity based distribution grid tariff
(International Conference on the European Energy Market;2020, Chapter; Peer reviewed, 2020)This paper presents the status of regulation related to distribution grid tariffs in Norway, and household customers’ assessment of having such a tariff scheme. The paper is presenting results from a Norwegian pilot where ... -
How much can novel solid sorbents reduce the cost of post-combustion CO2 capture? A techno-economic investigation on the cost limits of pressure–vacuum swing adsorption
(Peer reviewed; Journal article, 2021)This paper focuses on identifying the cost limits of two single-stage pressure–vacuum swing adsorption (PVSA) cycles for post-combustion CO2 capture if the ‘‘ideal’’ zero-cost adsorbent can be discovered. Through an ... -
How to accurately fast-track sorbent selection for post-combustion CO2 capture? A comparative assessment of data-driven and simplified physical models for screening sorbents
(Peer reviewed; Journal article, 2023)The recent discovery of a multitude of hypothetical materials for CO2 capture applications necessitated the development of reliable computational models to aid the quest for better-performing sorbents. Given the computational ... -
