Liquid air energy storage (LAES) systems are a promising technology for storing electricity due to their high energy density and lack of geographic constraints. However, some LAES systems still have relatively low round-trip efficiencies. This work aims to improve LAES system performance through optimization strategies.
Liquid Air Energy Storage (LAES) is a promising technology due to its geographical independence, environmental friendliness, and extended lifespan . However, the primary challenge lies in the relatively low efficiency of energy-intensive liquefaction processes.
A novel framework for optimizing Liquid Air Energy Storage processes is provided. Dynamic link libraries effectively integrate into equation-based settings. Model's nonlinearities are properly managed by derivative-based optimization method. Compared to a base case, an improvement of 63 % in round-trip efficiency was found.
