Effective use and integration of renewable energy sources, coupled with different storage options, is an emerging priority within the Department of Defense. One promising method of energy storage is a Liquid Air Energy Storage system (LAES), which uses renewable energy in excess of immediate demand to make and cryogenically store liquid air for later expansion through a turbine to generate power when needed. This paper outlines a modeling and simulation approach to determining the design and material specifications based on a supply requirement of a renewable energy fed LAES. The source power requirement was based on the available renewable generation at the Naval Postgraduate School (NPS) Turbo-Propulsion Laboratory of 18 kW. These models revised previous validated versions, which were used to design a small-scale theoretical LAES system, to yield an integrated, practical, building-scale simulation. The expansion and generation portion of a LAES system was simulated for a Linde-Hampson cycle using the process modeling software Aspen HYSYS. The results from this model, along with a demand side analysis, will be used to map the trade space of a LAES system and determine potential commercial components for system construction. This work is part of a larger effort to determine the effectiveness of potential energy storage solutions for naval facilities or Forward Operating Bases (FOB).
