Renewable energy generation is intermittent, necessitating energy storage subsystems to provide electricity during periods of reduced or no power generation. Liquid air energy storage (LAES) systems, with their high energy density and scalability, are a promising method to store energy for intermittent systems. This thesis presents two independent papers for use in the systems engineering process during the conceptualization and requirements stage of designing and development a LAES system. The first paper is a closed-form method of calculating the compressor work for a modified simple Linde-Hampson system and liquid yield of a binary mixture of nitrogen and oxygen using only their respective pure fluid tables. This tool provides a methodology to check holistically a vast amount of different potential binary mixtures for use in a LAES system. The second paper is an energy and exergy analysis of a LAES system in order to map the trade space and identify optimum operating ranges. Additionally, this paper provides insight in to potential measures of performance and effectiveness of the LAES system. Finally, this thesis presents a valuable Excel add-in tool used to download fluid chemistry tables from the National Institute of Standards and Technology website.
