“…RTE is therefore significantly reduced due to these irreversibilities. However, as reported by Odukomaiya et al, it must be added that, at the Oak Ridge National Laboratory, a small-size aerial prototype of hydro-pneumatic energy storage was able to reach RTE ranging from 66% to 82% thanks to the innovative heating and cooling of the air with water spray and thanks to the utilization of waste heat [13]. In all cases, unlined natural caverns or unlined mines must also be located deeply underground to maintain the tightness of compressed air through a hydrostatic containment by ground water (i.e., a 1000 m depth to contain a pressure of 10 MPa).…”

A fast-paced energy transition needs a higher penetration of renewables, of heating and cooling in the worldwide energy mix. With three novelties 1-of using shallow high-pressure LRC (Lined Rock Cavern) excavated close to storage needs, 2-of using a slow-moving CO2 piston applying steady pressure on the hydro part of UPHES (Underground Pumped Hydro Energy Storage) and 3-of relying on inexpensive thermal stores for long-duration storage, CO2 UPHES coupled with PTES (Pumped Thermal Electricity Storage) could become, at expected Capex cost of only 20 USD/kWh electrical, a game-changer by allowing the complete integration of intermittent renewable sources. Moreover, even though this early conceptual work requires validation by simulation and experimentation, CO2 UPHES as well as UPHES-PTES hybrid storage could also allow a low-cost and low-emission integration of intermittent renewables with future district heating and cooling networks.

“…The TES in the isothermal CAES concept is very similar to the ACAES, but for the high‐temperature avoidance. Generally, there are several ways of enhancing heat transfer for achieving isothermal compression/expansion: liquid piston, porous media insert, water spray, and water/air two‐phase foam . Volume energy density of compressed air is low and large‐scale expensive pressure vessels are necessary for storing a large amount of compressed air.…”

“…Generally, there are several ways of enhancing heat transfer for achieving isothermal compression/expansion: liquid piston, porous media insert, water spray, and water/air two-phase foam. [105][106][107][108][109] Volume energy density of compressed air is low and large-scale expensive pressure vessels are necessary for storing a large amount of compressed air. In the LAES and supercritical CAES systems, liquid air is stored in insulated tanks at low temperature and normal pressure, thereby achieving higher volume energy density and lower cost for pressure vessels.…”

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.

“…The idea of this system born to improve the efficiency of the system, because it is more efficient to pump the liquid than the air inside of the vessel. In the literature, Odukomaiya et al [23] analyze this particular CAES system. Our idea is to use this system for small energy applications, where it is necessary to obtain self-sufficient energy.…”

In order to enhance the spreading of renewable energy sources in the Italian electric power market, as well as to promote self-production and to decrease the phase delay between energy production and consumption, energy storage solutions are catching on. Nowadays, in general, small size electric storage batteries represent a quite diffuse technology, while air liquid-compressed energy storage solutions are used for high size. The goal of this paper is the development of a numerical model for small size storage, environmentally sustainable, to exploit the higher efficiency of the liquid pumping to compress air. Two different solutions were analyzed, to improve the system efficiency and to exploit the heat produced by the compression phase of the gas. The study was performed with a numerical model implemented in Matlab, by analyzing the variation of thermodynamical parameters during the compression and the expansion phases, making an energetic assessment for the whole system. The results show a good global efficiency, thus making the system competitive with the smallest size storage batteries.
