“…Therefore, the development of alternative energy storage technologies is strongly encouraged. From these efforts, two recently proposed medium-to-large-scale thermo-mechanical energy storage technologies, namely liquid air energy storage (LAES) [22] and pumped thermal electricity storage (PTES) [23], have emerged. A thermo-economic analysis and comparison of these two technologies [24] showed that PTES can achieve higher roundtrip efficiencies and appears to be economically more competitive at higher electricity-buying prices whereas LAES has lower power/energy capital costs and a lower levelised cost of storage (LCOS).…”

“…p A1 and T A1 are the same as the ambient temperature and the ambient pressure. The isentropic efficiencies of all equipment are selected based on the reasonable range of equipment efficiencies mentioned in the studies by Lee and You and Zhang et al [ 24,26 ] The storage pressure is set to 0.2 MPa in this article referring to the study by Kim et al, [ 31 ] as the storage pressure close to atmospheric pressure is generally selected to achieve large‐scale storage of liquid air. Meanwhile, properly increasing the storage pressure can increase the liquefaction rate and improve the overall efficiency of the system.…”

“…To maximize the advantages of integration between LNG regasification and the LAES system, they proposed an LAES system combined with organic Rankine cycle (ORC) and LNG direct expansion. [ 24 ] Park et al [ 25 ] proposed adding LAES to a LNG gasification power generation. The LAES system realized air liquefaction by utilizing the cold energy during LNG gasification, and the electric exchange efficiency of the overall integrated system reached 95.2%.…”

The integrated system of regasification of liquefied natural gas (LNG) and liquid air energy storage (LAES) has advantages of improving the LAES system efficiency and energy grade matching utilization of the LNG cold energy. But the influence of the cold energy storage efficiency on the combined system is ambiguous and the decoupling mechanism between the energy storage and release processes with the addition of the LNG cold energy was seldom investigated. Thus, a hybrid LAES system using LNG is proposed. The thermodynamic model is established to analyze the system performance. The influence of key parameters on the system and the removal of the coupling effect are originally analyzed. The results show that the electricity storage efficiency (ηese) and exergy efficiency (ηexe) of the typical operational condition can reach 107.3% and 49.4%, respectively. With the cold energy storage efficiency varying from 0% to 100%, the ηese and ηexe increase by 18.0% and 4.4% averagely. Furthermore, to investigate the influence mechanism of introducing LNG to the LAES system, the performance of four different systems is compared. With the decoupling between the energy storage and release processes, the ηese is improved obviously and the ηexe can be maintained at a high level.

“…The link between these keywords can be explained since the LAES is often classified as an alternative storage solution to the actual large scale energy storage technologies. Furthermore, since cryogenics is involved as a storage energy vector, LAES is characterized by the advantage that it can be integrated with waste cold energy resources such as the regasification of liquefied natural gas [8,37,48]. Other connections, external to the energy storage cluster, were with "electric energy storage", "liquefaction", "renewable energy", and "thermodynamics".…”

The increasing penetration of renewable energy has led electrical energy storage systems to have a key role in balancing and increasing the efficiency of the grid. Liquid air energy storage (LAES) is a promising technology, mainly proposed for large scale applications, which uses cryogen (liquid air) as energy vector. Compared to other similar large-scale technologies such as compressed air energy storage or pumped hydroelectric energy storage, the use of liquid air as a storage medium allows a high energy density to be reached and overcomes the problem related to geological constraints. Furthermore, when integrated with high-grade waste cold/waste heat resources such as the liquefied natural gas regasification process and hot combustion gases discharged to the atmosphere, LAES has the capacity to significantly increase the round-trip efficiency. Although the first document in the literature on the topic of LAES appeared in 1974, this technology has gained the attention of many researchers around the world only in recent years, leading to a rapid increase in a scientific production and the realization of two system prototype located in the United Kingdom (UK). This study aims to report the current status of the scientific progress through a bibliometric analysis, defining the hotspots and research trends of LAES technology. The results can be used by researchers and manufacturers involved in this entering technology to understand the state of art, the trend of scientific production, the current networks of worldwide institutions, and the authors connected through the LAES. Our conclusions report useful advice for the future research, highlighting the research trend and the current gaps.
