      HighEFF Webinar series – celebrating one year

      It is now a year since we launched the first HighEFF webinar, the 16th of February 2022. Since then, there have been 17 seminars giving HighEFF partners an opportunity to learn more about thermal energy storage technology, how to make the aluminum industry greener and heat pump technology for industrial applications, to mention just a few. The webinar series have been a success with good participation from our industry partners. On average, industry participation has been 34%.

      For those of you not taking part in these webinars yet, there are still many more to come. The next one is about utilization of low temperature heat at Elkem Thamshavn, and will be presented by Bjørn Saugestad, the plant manager. The next five webinars are listed below.

      The webinars will start at 11:30 with 20-30 minutes presentation of topics related to HighEFF's thematic areas and continue with questions and discussions until 12:30 at the latest.

      Presenter, topic and description for each presentation will be updated in the webinar section of the HighEFF events page. If you missed some of the earlier webinars, they are recorded and available via the eRoom.

      The next webinars are:

      • Utilization of low temperature heat at Elkem Thamshavn - 1 March
        Presenter: Bjørn Saugestad, Elkem
      • FRIENDSHIP-Development of high temperature heat pump concepts based on water (R718) and CO2 (R744) as working medium - 15 March
        Presenter: Ole Marius Moen, SINTEF Energi
      • NEC SOCTES: Innovative state-of-charge and output control of PCM-TES systems - 29 March
        Presenter: Magnus Rotan, SINTEF Energi
      • SiOs importance for the energy use in Si production – 12 April
        Presenter: Sethulakshmy Jayakumari, SINTEF Industry
      • Integrated CO2 heat pumping systems for hotels – 26 April
        Presenter: Silje Smitt, NTNU (Carrier)
      We encourage you to make use of this opportunity to learn and discuss on energy efficiency related topics with colleagues across the Centre!
