Brayton cycle engines compress and heat air with a fuel suitable for an internal combustion engine. For example, burning natural gas or biogas heats compressed air, and then a conventional gas turbine engine or the rear portion of a jet engine expands it to produce work. Compressed air engines can recharge an electric battery. The apparently-defunct

Erdemir et al. [15] proposed a new CAES system combined with a hydrogen storage device, which has a two-chamber storage system with air and hydrogen stored in two separate chambers. The two chambers work in a synchronous manner, with one being compressed and the other being expanded to achieve constant pressure operation for both …
As shown in Fig. 1, the energy storage technology can be divided into short-term (several seconds to minutes), medium-term (several minutes to hours), and long-term (several hours to days and months) according to discharge time, power rating, and module size [4].Short- and medium-term energy storage systems, such as flywheel energy storage [5], …
Sezgin et al. [21] have studied the integration of hydrogen energy systems into underwater applications and storage techniques of hydrogen and oxygen. Bartela [22] have proposed a hybrid energy storage using compressed air and hydrogen, which has about 40% of storage efficiency.
Gas storage can take the form of mechanical energy storage (i.e. compressed air energy storage (CAES)) or chemical energy storage in a power-to-gas scheme, using e.g. hydrogen or synthetic methane [10]. Both approaches are typically discussed as large- or grid-scale energy storage options [11], [12].
An integration of compressed air and thermochemical energy storage with SOFC and GT was proposed by Zhong et al. [134]. An optimal RTE and COE of 89.76% and 126.48 $/MWh was reported for the hybrid system, respectively. Zhang et al. [135] also achieved 17.07% overall efficiency improvement by coupling CAES to SOFC, GT, and ORC hybrid system.
