The increasing global demand for reliable and sustainable energy sources has fueled an intensive search for innovative energy storage solutions . Among these, liquid air energy storage (LAES) has emerged as a promising option, offering a versatile and environmentally friendly approach to storing energy at scale .
Energy storage systems as a part of energy secure supply have the ability to take up a certain amount of energy, store it in a storage medium for a suitable period of time, and release it in a controlled manner after a certain time delay.
Compressed air energy storage (CAES) is an effective solution for balancing this mismatch and therefore is suitable for use in future electrical systems to achieve a high penetration of renewable energy generation.
Compressed air energy storage may be stored in undersea caves in Northern Ireland. In order to achieve a near- thermodynamically-reversible process so that most of the energy is saved in the system and can be retrieved, and losses are kept negligible, a near-reversible isothermal process or an isentropic process is desired.
1) Mechanical energy storage mainly includes flywheel energy storage, pumped hydro energy storage (PHES), compressed air energy storage (CAES) and liquid air energy storage. 2) Thermal energy storage primarily encompasses sensible heat storage, latent heat storage, and thermochemical storage.
With excellent storage duration, capacity, and power, compressed air energy storage systems enable the integration of renewable energy into future electrical grids. There has been a significant limit to the adoption rate of CAES due to its reliance on underground formations for storage.
Compressed Air Energy Storage: Types, systems and applications
Compressed air energy storage (CAES) uses excess electricity, particularly from wind farms, to compress air. Re-expansion of the air then drives machinery to recoup the electric power. Prototypes have capacities of several hundred MW. Challenges lie in conserving the thermal energy associated with compressing air and leakage of that heat ...

Chemical storage of renewable energy
Although the work of Dinh et al. is an important step toward chemical storage of renewable energy, challenges remain. Their reactor, and indeed nearly all CO 2 -reduction reactors in the literature, makes products which are either entrained in the CO 2 stream or dissolved in the electrolyte, leaving product separation as an unsolved challenge ( 10 ).
