Comprehensive energy, exergy, and economic analyses and multi-objective optimization of a compressed air energy storage hybridized with a parabolic trough solar collectors were performed by Su [35]. Zeotropic mixtures were employed for performance improvement in the ORC subsystem.
The investment costs of the battery make this hybrid system unprofitable. To have this system economically viable, the cost of storage needs to be reduced by 60%–90% from 300 USD/kWh. Olateju et al. [25] conducted a techno-economic appraisal for a 563 MW integrated wind-hydrogen power plant with energy storage.
Households accounted for 35% of total UK electricity consumption in 2019 and have considerable potential to support the target of net-zero CO 2 emissions by 2050. However, there is little understanding of the potential to reduce emissions from household energy systems using emissions-responsive battery charging, and existing investigations …

The optimal dispatch strategies for thermal energy storage and electrical energy storage according to their response characteristics are proposed in joint energy and ancillary services markets. The economic benefits of storage systems are maximized by allocating the flexibility capacity to multiple flexibility services optimally as mixed integer …
Energy storage can also improve the viability of wind or solar energy, which can be intermittent due to fluctuating weather conditions. This not only improves the economic case for decarbonisation; it also improves the prospects for off-grid distributed energy systems, potentially undermining traditional utilities.
