Free QuoteLiquid air energy storage is one of the most recent technologies introduced for grid-scale energy storage. As the title implies, this technology offers energy storage through an air liquefaction process. High energy storage density, no geographical limitation, and applicability for large-scale uses are some of the advantages of this technology.
To improve the performance and environmental friendliness of the conventional design of this technology, a novel liquid air energy system combined with high-temperature thermal energy storage, thermoelectric generator, and organic Rankine cycle is proposed in the present article.
When there is insufficient storage capacity to balance seasonality, as in some European and most emerging Asian countries, LNG import capacity is an option to manage seasonal natural gas and electricity demand variations, thus providing higher flexibility to the energy system .
The liquefaction ratio and the amount of boil-off gas (BOG) varies according to the natural gas extraction rate to meet the liquefaction capacity. Therefore, utilizing produced BOG and minimizing wasted BOG is key from an economic point of view. This study performed profit optimization with various extraction rates.
Gas storage can be considered as a flexibility tool as well, since it enables the optimisation of natural gas transmission and ensures continuity of the service , . Together, LNG import capacity and gas storage have strategic and speculative functions.
In addition to energy and exergy efficiencies, energy density is another important parameter that can be used to compare the performance and capacity of the storage systems.
