When the system is discharged, the air is reheated through that thermal energy storage before it goes into a turbine and the generator. So, basically, diabatic compressed air energy storage uses natural gas and adiabatic energy storage uses compressed – it uses thermal energy storage for the thermal portion of the cycle. Neha: Got it. Thank you. - Download [PDF]

The energy storage system includes hydrogen energy storage for hydrogen production, and the charging station can provide services for electric vehicles and hydrogen vehicles at the same time.
Hydrogen can be stored physically as either a gas or a liquid. Storage of hydrogen as a gas typically requires high-pressure tanks (350–700 bar [5,000–10,000 psi] tank pressure). Storage of hydrogen as a liquid requires cryogenic temperatures because the boiling point of hydrogen at one atmosphere pressure is −252.8°C.
The Sankey diagrams indicate that due to the inefficiencies of hydrogen or e-fuel production, storage, transportation, dispensing, and usage, providing 1 unit of energy to the wheels or to thrust requires 4.5–6.7 units (direct hydrogen) and 7.3–11.9 units (e-fuel) of initial renewable electricity input compared with 1.4–1.9 units for ...
