A Comparison of Post-combustion Capture Technologies for the NGCC
Subramanian, Avinash Shankar Rammohan; Jordal, Aina Benedikte Kristin; Anantharaman, Rahul; Hagen, Brede Andre Larsen; Roussanaly, Simon (Journal article; Peer reviewed, 2017)Four different post-combustion capture technologies are compared for the same NGCC (electric efficiency 58.1% without CO2 capture). The technologies are aqueous amine, polymeric membranes, a low temperature sorbent and ... -
A new approach to the identification of high-potential materials for cost-efficient membrane-based post-combustion CO2 capture
Roussanaly, Simon; Anantharaman, Rahul; Lindqvist, Karl Erik Artur; Hagen, Brede Andre Larsen (Journal article; Peer reviewed, 2018)Developing “good” membrane modules and materials is a key step towards reducing the cost of membrane-based CO2 capture. While this is traditionally being done through incremental development of existing and new materials, ... -
Equation-oriented methods for optimizing Rankine cycles using radial inflow turbine
Hagen, Brede Andre Larsen; Andresen, Trond; Nekså, Petter (Peer reviewed; Journal article, 2022)This paper presents methods for optimizing the design and the performance of Rankine cycles using radial inflow turbines. Both methods follow a novel equation-oriented approach and involve a single mathematical problem ... -
Gradient-based design optimization and off-design performance prediction of Rankine cycles and Radial Inflow Turbines
Hagen, Brede Andre Larsen (Doctoral theses at NTNU;2022:147, Doctoral thesis, 2022)A major fraction of today's electricity is generated by Rankine cycle power systems utilizing the thermal energy of fossil sources such as coal and natural gas, or nuclear energy. However, the carbon content in the fossil ... -
Heat-to-power conversion from variable surplus heat sources utilizing a thermal energy storage
Lingaas, Simon Johan Nilsen (Master thesis, 2019)Målet med dette arbeidet var å undersøke den potensielle nytten av termisk buffring i et varmegjennvinningssystem. Arbeidet undersøkte muligheten for å integrere en form for termisk lagring inn i et varmegjennvinningssystem ... -
Sensitivity Analysis of O&M Costs for Offshore Wind Farms
Hagen, Brede Andre Larsen (Master thesis, 2013)The offshore wind farm industry is challenged by high costs related to operation and maintenance (O&M), and a study on how to significantly reduce these costs is essential to make this industry competitive with other energy ...
