Integration of chemical looping combustion for cost-effective CO2 capture from state-of-the-art natural gas combined cycles
(Peer reviewed; Journal article, 2020)Chemical looping combustion (CLC) is a promising method for power production with integrated CO2 capture with almost no direct energy penalty. When integrated into a natural gas combined cycle (NGCC) plant, however, CLC ... -
Integration of Cold Thermal Energy Storage at a Pelagic Fish Processing Plant: A Modelling Approach
(Chapter, 2023)Energy intensive sectors such as food processing are paying more and more attention towards energy conservation and reducing their total carbon footprint. The energy demand of a pelagic fish processing plant has been ... -
Integration of gravity-fed evaporators in CO2 based heat-pump chillers
(Chapter, 2022)This study is carried out to model a gravity-fed evaporator for CO2 based heat-pump chillers. The gravity-fed evaporator loop consists of a separator, a downcomer, a heat exchanger, and a riser. The working principle is ... -
Integration of heat pumps with natural working fluids into a neighborhood energy system
(Chapter, 2020)Combining heat pumps (HP) with other renewables, e.g. solar thermal collectors, photovoltaics and energy storage systems can contribute to the growth of future zero emission societies. This article investigates HP integration ... -
Integration of high temperature heat pumps with natural working fluids into a neighborhood energy system
(Master thesis, 2020)Det er flere eksisterende teknologier som er tilgjengelig for anvendelse av høytemperatur varmepumper. Høytemperatursvarmepumper kan brukes til varmtvannsberedning og romoppvarming. De kan også brukes til industrielle ... -
Integration of LNG Regasification and Air Separation Units
(Master thesis, 2017)Through the various LNG cold recovery applications, cryogenic air separation is the only one recovering the coldest range of exergy, which is also the most valuable. Several designs of integrated ASU and LNG regasification ... -
Integration of Methods for Environmental Assessment and Investment Analysis
(Master thesis, 2010)Background, aim and scope. In this thesis a framework for integrating life cycle assessment and investment analysis is derived, aimed to (1) unite economic and environmental perspectives, and (2) strengthen system borders. ... -
Integration of R744 and R290 Heat Pumps for Two-family Houses
(Master thesis, 2022)Forbruk av varmt tappevann og romoppvarming er store energiposter, og st˚ar for det meste av energien som leveres til boliger i kalde klima. Varmepumpesystemer utnytter energi i omgivelsene for ˚a redusere bruk av elektrisk ... -
