Decarbonizing integrated chlor-alkali and vinyl chloride monomer production: Reducing the cost with industrial flexibility
Foslie, Sverre Stefanussen; Straus, Julian; Knudsen, Brage Rugstad; Korpås, Magnus (Peer reviewed; Journal article, 2023)Industrial demand response will become increasingly important in power grids with high shares of variable renewables, yet the existing knowledge on how the industrial electricity demand and flexibility will change with the ... -
Design of Centrifugal Pump for Produced Water
Foslie, Sverre Stefanussen (Master thesis, 2013)During the spring of 2008, Jón Bergmann Heimisson developed a pump design program in Matlab. The program has been further developed during the work with this thesis, as well as in the author's preceding project thesis, ... -
Enhancing grid hosting capacity with coordinated non-firm connections in industrial energy communities
Bjarghov, Sigurd Nikolai; Foslie, Sverre Stefanussen; Askeland, Magnus; Rana, Rubi; Taxt, Henning (Peer reviewed; Journal article, 2024)A significant increase in grid connection requests from industrial customers has lead to long connection queues. Combined with long lead times on grid construction, the result is significant socioeconomic losses due to ... -
Green or blue? Enabling industrial decarbonization and demand response with hydrogen for high temperature process heating
Foslie, Sverre Stefanussen; Straus, Julian; Korpås, Magnus (Chapter, 2023)Vinyl chloride monomer production coupled with chlor-alkali electrolysis is an industrial process that requires high temperature process heat. One option for providing this process heat in a decarbonized energy system is ... -
Höchtemperatur-Wärmepumpen mit natürlichen Kältemitteln : Fallstudien zur HTWP-Integration für industrielle Kälte- und Prozessheisswasserherstellung
Schlemminger, Christian; Ahrens, Marcel Ulrich; Foslie, Sverre Stefanussen; Moen, Ole Marius; Bantle, Michael; Hafner, Armin; Jenssen, Sigmund (Chapter, 2021)Thermische Prozesse in der Nahrungsmittelindustrie, wie z. B. Molkereien sind oftmals eine Kombination aus Erwärmung und Abkühlung eines Produktes. Prozesskühlung wird dabei meistens mittels einer Wärmepumpe erzielt, wobei ... -
Industrial energy communities: Energy storage investment, grid impact and cost distribution
Berg, Kjersti; Foslie, Sverre Stefanussen; Farahmand, Hossein (Journal article; Peer reviewed, 2024)Energy communities are a way for end-users to contribute to the green shift, by installing distributed energy resources such as photovoltaic panels. The focus of energy community studies has mainly been on residential and ... -
Integrated design and operational optimization of energy systems in dairies
Foslie, Sverre Stefanussen; Knudsen, Brage Rugstad; Korpås, Magnus (Journal article; Peer reviewed, 2023)Around 70% of worldwide industrial energy use is today based on fossil energy. Electrification of low temperature heat in this sector is pointed out as a key measure to reduce emissions. A large amount of the low temperature ... -
Integrated high temperature heat pumps and thermal storage tanks for combined heating and cooling in the industry
Ahrens, Marcel Ulrich; Foslie, Sverre Stefanussen; Moen, Ole Marius; Bantle, Michael; Eikevik, Trygve Magne (Peer reviewed; Journal article, 2021)This study investigates the integrated heat pump system of a green-field dairy located in Bergen, Norway. The purpose of the study is to determine the energy consumption and system performance. The dairy features a novel ... -
Performance analysis of high temperature heat pumps and thermal energy storages for a dairy
Ahrens, Marcel Ulrich; Brækken, August; Foslie, Sverre Stefanussen; Moen, Ole Marius; Lovas, Kim Andre; Bantle, Michael; Hafner, Armin; Eikevik, Trygve Magne (Chapter, 2022)This paper analyses the performance of the integrated energy system of an existing dairy in Bergen, Norway. The investigated dairy has an innovative solution for the thermal process supply by using only heat pumps and ... -
Performance of high temperature heat pump for simultaneous and efficient production of ice water and process heat
Schlemminger, Christian; Svendsen, Eirik Starheim; Foslie, Sverre Stefanussen; Bantle, Michael; Bamigbetan, Opeyemi Olayinka; Nekså, Petter (Chapter, 2019)Industrial processes like milk production often require simultaneous cooling and heating at temperature of 1 °C to 10 °C and 90 °C to 120 °C, respectively. High temperature heat pumps (HTHP) with natural working fluids are ...
