    • Measured load profiles and heat use for “low energy buildings” with heat supply from district heating 

      Ulseth, Rolf; Lindberg, Karen Byskov; Georges, Laurent; Alonso, Maria Justo; Utne, Åmund (Journal article; Peer reviewed, 2017)
      In the development towards nearly zero energy buildings (nZEB) the load profiles for the heat demand and the heat use of the buildings are expected to be changed considerably compared to the situation today. This change ...
    • Possibilities for energy recovery by steam compression cycles 

      Foslie, Sverre Stefanussen (HighEFF-rapport;D3.2_2017.05, Research report, 2017)
      A significant amount of the industrial energy consumption is related to process heat. Several industries use heat in ranges reachable by heat pumps, and temperatures from 100-200℃ are especially needed in the paper and the ...
    • Pressure-Dependent Propagation of Streamers under Step Voltage in a long Point-Plane Gap in Transformer Oil 

      Linhjell, Dag; Lundgaard, Lars Esben; Unge, M.; Hjortstam, Olof (Peer reviewed; Journal article, 2020)
      The effect of pressure on positive and negative streamer propagation in a mineral transformer oil is studied in an 80 mm point-plane gap under step voltage. Increased pressure causes reduced stopping length for non-breakdown ...
    • A standardized Approach to Multi-criteria Assessment of CCS Chains 

      Jakobsen, Jana Poplsteinova; Roussanaly, Simon; Mølnvik, Mona J.; Tangen, Grethe (Peer reviewed; Journal article, 2013)
      For a commercial Carbon Capture and Storage (CCS) chain to be successful, it must satisfy a whole range of requirements: technical, economic, environmental, safety, and societal. A comprehensive, understandable and ...
    • State-of-the-Art for the use of Phase-Change Materials in Tanks Coupled with Heat Pumps 

      Pardiñas, Ángel Á.; Alonso, Maria Justo; Diz, Rubén; Kvalsvik, Karoline Husevåg; Fernandez-Seara, Jose (Journal article; Peer reviewed, 2017)
      With the goal of increasing heat storage in the same accumulation volumes, phase-change materials are considered. There are different substances with different phase-change temperatures that can be used for storing heating ...
