“…I‐CAES is an emerging technology, which does not require multiple stages of compression, cooling, heating, and expansion of air, compared with conventional CAES. I‐CAES eliminates the use of auxiliary storage systems, air compressors, and air turbines, as are used in conventional CAES, and, rather, uses the liquid piston machinery which compresses the air more efficiently (compression efficiency up to 95%); subsequently, overall efficiency of 70% can be obtained …”

Also, the overall efficiency of conventional CAES is around 40% and goes as high as 80% in case of some advanced CAES technologies.…”

Summary The demand of electric energy is increasing globally, and the fact remains that the major share of this energy is still being produced from the traditional generation technologies. However, the recent trends, for obvious reasons of environmental concerns, are indicating a paradigm shift towards distributed generation (DG) incorporating renewable energy resources (RERs). But there are associated challenges with high penetration of RERs as these resources are unpredictable and stochastic in nature, and as a result, it becomes difficult to provide immediate response to demand variations. This is where energy storage systems (ESSs) come to the rescue, and they not only can compensate the stochastic nature and sudden deficiencies of RERs but can also enhance the grid stability, reliability, and efficiency by providing services in power quality, bridging power, and energy management. This paper provides an extensive review of different ESSs, which have been in use and also the ones that are currently in developing stage, describing their working principles and giving a comparative analysis of important features and technical as well as economic characteristics. The wide range of storage technologies, with each ESS being different in terms of the scale of power, response time, energy/power density, discharge duration, and cost coupled with the complex characteristics matrices, makes it difficult to select a particular ESS for a specific application. The comparative analysis presented in this paper helps in this regard and provides a clear picture of the suitability of ESSs for different power system applications, categorized appropriately. The paper also brings out the associated challenges and suggests the future research directions.

“…Camargos et al built a simplified prototype of isobaric hydro‐pneumatic concept and found that an experimental conversion efficiency of 45% was approached. Maisonnave et al designed an isothermal and isobaric hydro‐pneumatic storage system by introducing the liquid piston concept and UWCAES concept as shown in Figure .Besides the aforementioned CAES for storing marine renewable energies, the Keuka Energy Company proposed to integrate LAES with offshore wind turbines on a floating V‐shaped platform that could contain liquid air. Currently, a 125‐kW 1:100 prototype system has been completed and a 25 MW project has been scheduled.…”

Summary Marine renewable energies are promising enablers of a cleaner energy future. Some technologies, like wind, are maturing and have already achieved commercial success. Similar to their terrestrial counterparts, marine renewable energy systems require energy storage capabilities to achieve the flexibility of the 21st century grid demand. The unique difficulties imposed by a harsh marine environment challenge the unencumbered rise of marine renewable energy generation and storage systems. In this study, the fundamentals of marine renewable energy generation technologies are briefed. A comprehensive review and comparison of state‐of‐the‐art novel marine renewable energy storage technologies, including pumped hydro storage (PHS), compressed air energy storage (CAES), battery energy storage (BES), hydrogen energy storage (HES), gravity energy storage (GES), and buoyancy energy storage (ByES), are conducted. The pros and cons, and potential applications, of various marine renewable energy storage technologies are also compiled. Finally, several future trends of marine renewable energy storage technologies are connoted.

“…It was found that a round‐trip efficiency of approximately 71% could be achieved. On the basis of the basic UWCAES system, Maisonnave et al further developed an isothermal UWCAES concept by integrating a hydro‐pneumatic hybrid system. To date, most studies focused on the system design and efficiency evaluation based on either energy or exergy analysis.…”

Energy, exergy, and sensitivity analyses of underwater compressed air energy storage in an island energy system

et al. 2019

Summary An underwater compressed air energy storage (UWCAES) system is integrated into an island energy system. Both energy and exergy analyses are conducted to scrutinize the performance of the UWCAES system. The analyses reveal that a round‐trip efficiency of 58.9% can be achieved. However, these two analyses identify different directions for further improvement. The heat exchangers, expanders, compressors, electric motors, and generators account for the most exergy destruction. A sensitivity analysis is also conducted to investigate the importance of different input parameters on the round‐trip exergy efficiency of the UWCAES system. The results of both local and global analyses show that the round‐trip exergy efficiency is most sensitive to the isentropic efficiency of the expanders and compressors, and the efficiencies of the electric motors and generators. The impacts of the heat exchangers, the self‐discharge rate of the air accumulator, the inner diameter of the pneumatic pipelines, and the insulation thickness of the hot‐oil tank on the round‐trip exergy efficiency are shown to be highly nonlinear.
