• Evaluation of Gas Composition from Laboratory Scale Electrolysis Experiments with Anodes of Different Sulphur Content 

      Aarhaug, Thor Anders; Kjos, Ole Sigmund; Gudbrandsen, Henrik; Ferber, Alain Marc C; Ratvik, Arne Petter (Journal article; Peer reviewed, 2016)
      With the anticipated decrease in available anode raw materials, future anodes are expected to contain higher levels of impurities. Currently the implications of this are being investigated through evaluation of electrochemical ...
    • Mapping of hydrogen fuel quality in Europe 

      Aarhaug, Thor Anders; Kjos, Ole Sigmund; Ferber, Alain Marc C; Hsu, Jong Pyong; Bacquart, Thomas (Peer reviewed; Journal article, 2020)
      As part of FCH-JU funded HyCoRA project running from 2014 to 2017, 28 gaseous and 13 particulate samples were collected from hydrogen refueling stations in Europe. Samples were collected with commercial sampling instruments ...
    • Online monitoring of aluminium primary production gas composition by use of Fourier-transform infrared spectroscopy 

      Aarhaug, Thor Anders; Ferber, Alain Marc C; Kjos, Ole Sigmund; Gaertner, Heiko (Journal article; Peer reviewed, 2014)
      Online monitoring of aluminium primary production raw gas is challenging due to the high concentration of HF in the presence of water. Tunable Diode Laser (TDL) analyzers retrofitted with sapphire optical windows allow for ...
    • Validation of Online Monitoring of PFC by QCL with FTIR Spectroscopy 

      Aarhaug, Thor Anders; Ferber, Alain Marc C; Gaertner, Heiko; Kolås, Steinar; Ryman, Sven Olof; Geiser, Peter (The Minerals, Metals & Materials Series;2367-1181, Peer reviewed; Journal article, 2018)
      Monitoring of perfluorocarbon (PFC) evolution from aluminium smelting is gaining attention, not only because of their high greenhouse gas potentials but also due to process optimization purposes. Conventionally, PFC ...
