Optimization of Liquid Air Energy Storage (LAES) using a Genetic Algorithm (GA)
Liu, Zhongxuan; Yu, Haoshui; Gundersen, Truls (Peer reviewed; Journal article, 2020)Renewable energy sources have a growing share in the energy market due to the threat from climate change, which is caused by emissions from fossil fuels. A future energy scenario that is likely to be realized is distributed ... -
Performance Improvements of Standalone Liquid Air Energy Storage
Liu, Zhongxuan (Doctoral theses at NTNU;2022:375, Doctoral thesis, 2022)Due to the threat of climate change, our energy systems tend to adopt lower-carbon energy sources, such as renewables. In addition, our energy systems are likely to follow another trend from very large centralized industrial ... -
Techno-economic Analysis of Different Liquid Air Energy Storage Configurations
Liu, Zhongxuan; Kim, Donghoi; Gundersen, Truls (Journal article; Peer reviewed, 2022)With the increasing use of renewables in energy systems, grid stability becomes a major issue due to the intermittent nature of energy sources such as solar and wind. To compensate for the unstable renewable energy sources, ...
