The biggest challenge with combining renewable energy into the electrical power system is the fact that the produced energy is intermittent. Solar energy is only available for usage when the sun is out and the sky is clear. A battery energy storage system (BESS) can solve this intermittency problem. The battery energy storage is necessary to help get a stable

The energy storage mode operates during off-peak times, where surplus electricity is used to drive the air compressors (ACs) and is converted to the energy of air pressure. Intercoolers (ICs) are set behind the ACs, and compression heat is carried away by thermal oil and stored in oil tanks (LOTs).
Local distribution is generally via the same mode; however, for bulk transport via pipeline, local delivery may also be accomplished by any other mode. Storage for plant outages and surge demands can be in geologic formations or as liquid hydrogen, and refueling stations can range from 50 kg to 6000 kg of hydrogen dispensed per day.
