Analyse av alternative driftsformer for ikke-elektrifiserte baner 2. utgave
Zenith, Federico; Møller-Holst, Steffen; Myklebust, Thor; Thomassen, Magnus; Tolchard, Julian R; Hovland, Jon; Thomassen, Tonje; Wittgens, Bernd; Bustad, Joakim; Landmark, Andreas; Tschentscher, Roman; Hansen, Olav (SINTEF rapport;2019:00997, Research report, 2019-09-30)SAMMENDRAG Alternative drivstoff og framdriftsteknologier er evaluert for ikke-elektrifiserte banestrekninger i Norge med fokus på godstrafikk. Denne rapporten er en revidert utgave av en rapport som opprinnelig ble skrevet ... -
Measuring the thermal conductivity of membrane and porous transport layer in proton and anion exchange membrane water electrolyzers for temperature distribution modeling
Bock, Robert; Karoliussen, Håvard; Seland, Frode; Pollet, Bruno; Thomassen, Magnus; Holdcroft, Steven; Burheim, Odne Stokke (Peer reviewed; Journal article, 2019)Water electrolyzers that use a membrane electrolyte between the electrodes are a promising technology towards mass production of renewable hydrogen. High power setups produce a lot of heat which has to be transported through ... -
Modeling Contact Resistance and Water Transport within a Cathode Liquid-Fed Proton Exchange Membrane Electrolyzer
Gerhardt, Michael; Østenstad, Jenny S.; Oyarce Barnett, Alejandro Ricardo; Thomassen, Magnus (Peer reviewed; Journal article, 2023)Conventional proton-exchange membrane (PEM) water electrolyzers use thicker membranes (>175 μm) than their PEM fuel cell counterparts (<25 μm), which reduces hydrogen crossover but also reduces electrolyzer efficiency due ... -
Online measurements of fluoride ions in proton exchange membrane water electrolysis through ion chromatography
Marocco, Paolo; Sundseth, Kyrre; Aarhaug, Thor Anders; Lanzini, Andrea; Santarelli, Massimo; Barnett, Alejandro Oyarce; Thomassen, Magnus (Peer reviewed; Journal article, 2021)This work investigates the online monitoring of fluoride ion concentration in proton exchange membrane water electrolysers (PEMWE) effluent water using an automated ion chromatography (IC) setup. Prototype catalyst coated ... -
Projecting the future cost of PEM and alkaline water electrolysers; a CAPEX model including electrolyser plant size and technology development
Reksten, Anita; Thomassen, Magnus; Møller-Holst, Steffen; Sundseth, Kyrre (Peer reviewed; Journal article, 2022)The investment costs of water electrolysis represent one key challenge for the realisation of renewable hydrogen-based energy systems. This work presents a technology cost assessment and outlook towards 2030 for alkaline ... -
Techno-economic analysis of freight railway electrification by overhead line, hydrogen and batteries: Case studies in Norway and USA
Zenith, Federico; Isaac, Raphael; Hoffrichter, Andreas; Thomassen, Magnus; Møller-Holst, Steffen (Journal article; Peer reviewed, 2019)Two non-electrified railway lines, one in Norway and the other in the USA, are analysed for their potential to be electrified with overhead line equipment, batteries, hydrogen or hydrogen-battery hybrid powertrains. The ...
