This paper discusses a particular case of CAES—an adiabatic underwater energy storage system based on compressed air—and its evaluation using advanced exergy analysis.
Advanced adiabatic compressed air energy storage (AA-CAES) system has drawn great attention owing to its large-scale energy storage capacity, long lifespan, and environmental friendliness. However, the performance of the air turbine during the discharging process is limited by the low temperature of the compression heat.
We review the literature on analytical models of advanced adiabatic compressed air energy storage plants with isochoric reservoirs, with a focus on the insights that can be extracted from the models.
In advanced adiabatic CAES (AA-CAES), the thermal energy generated by the compression of the air is not rejected, but captured in a thermal-energy storage (TES) before entering a reservoir. (We use “reservoir” as a generic term for both underground storage volumes such as caverns as well as for above-ground storage volumes such as tanks.)
New models developed for adiabatic reservoirs and turbomachinery, without throttling. Models give expressions for plant efficiency and storage capacity. Models can be used for initial plant design by estimating reservoir volumes. Reduced maximum process temperatures imply reduced plant efficiencies.
Thermodynamic Model In the thermodynamic model for the AA-CAES system, the assumptions are listed below: - The air circulates in the close loop cycle and is considered as an ideal gas. - Storage vessel is assumed to be well insulated and no heat loss across the vessel.
A novel water cycle compressed air energy storage system (WC-CAES) is proposed to improve the energy storage density (ESD) and round trip efficiency (RTE) of A-CAES. The new system decreases electricity consumption by recovering and reusing the hydraulic pressure of water.
Less than a decade ago, South Korean companies held over half of the global energy storage system (ESS) market with the rushed promise of helping secure a more sustainable energy future.
Energy overflow occurs when the electric current generated by a generator exceeds the power grid's load demand, leading to surplus energy that challenges system reliability. This issue causes challenges in power generation, including load shedding and operational inefficiencies.
The expansion is driven mainly by local governments and lacks coordination with new energy stations and the power grid. In some regions, a considerable storage oversupply could lead to conflicts in power-dispatch strategies across timescales and jurisdictions, increasing the risk of system instability and large-scale blackouts.
In general, they have not been widely used in electricity networks because their cost is considerably high and their profit margin is low. However, climate concerns, carbon reduction effects, increase in renewable energy use, and energy security put pressure on adopting the storage concepts and facilities as complementary to renewables.
