Pressurised storage vessels are also beneficial for liquefaction performance but result in higher air saturation temperature and thus lower storage energy density [55]. In this regard, Borri et al. [65] claimed 21% lower specific energy consumption for the liquefier when storing air at 4 bar rather than ambient conditions.
Furthermore, as underlined in Ref. [10, 18, 19], LAES is capable to provide services covering the whole spectrum of the electricity system value chain such as power generation (energy arbitrage and peak shaving), transmission (ancillary services), distribution (reactive power and voltage support) and "beyond the meter" end-use …

Latent heat storage is more attractive than sensible heat storage due to high energy density and constant temperature during phase change process [[56], [57], [58]]. TES based on thermochemical energy storage (TCES) offers inherently much higher energy density than sensible and latent heat based TES [ 59 ].
Although Liquid Air Energy Storage (LAES) has often been considered merely an advancement of CAES [12, 72] proposed to improve energy density, LAES is based on different physical principles. As was discussed, LAES stores electrical energy as heat, and not as mechanical energy, hence it should be considered a proper Carnot …

Phase change materials (PCMs) having a large latent heat during solid-liquid phase transition are promising for thermal energy storage applications. However, the relatively low thermal conductivity of the majority of promising PCMs (<10 W/ (m ⋅ K)) limits the power density and overall storage efficiency.
Technology Description. TES technologies are often grouped into three categories: 1) sensible heat (e.g., chilled water/fluid or hot water storage), 2) latent heat (e.g., ice storage), and 3) thermo-chemical energy. 5. For CHP, the most common types of TES are sensible heat and latent heat.
