Effective energy storage technologies represent one of the key elements to solving the growing challenges of electrical energy supply of the 21st century. Several energy storage systems are available, from ones that are technologically mature to others still at a research stage. Each technology has its inherent limitations that make its use economically or practically feasible only for specific applications. The present paper aims at integrating hydrogen generation into compressed air energy storage systems to avoid natural gas combustion or thermal energy storage. A proper design of such a hybrid storage system could provide high roundtrip efficiencies together with enhanced flexibility thanks to the possibility of providing additional energy outputs (heat, cooling, and hydrogen as a fuel), in a distributed energy storage framework. Such a system could be directly connected to the power grid at the distribution level to reduce power and energy intermittence problems related to renewable energy generation. Similarly, it could be located close to the user (e.g., office buildings, commercial centers, industrial plants, hospitals, etc.). Finally, it could be integrated in decentralized energy generation systems to reduce the peak electricity demand charges and energy costs, to increase power generation efficiency, to enhance the security of electrical energy supply, and to facilitate the market penetration of small renewable energy systems. Different configurations have been investigated (simple hybrid storage system, regenerate system, multistage system) demonstrating the compressed air and hydrogen storage systems effectiveness in improving energy source flexibility and efficiency, and possibly in reducing the costs of energy supply. Round-trip efficiency up to 65% can be easily reached. The analysis is conducted through a mixed theoretical-numerical approach, which allows the definition of the most relevant physical parameters affecting the system performance.

“…Generally speaking, a conventional hydrogen-based electrical energy storage system comprises an electrolyser, a hydrogen storage system (such as compressed gas or in solidstate as a metal hydride) and a fuel cell while in new architectures the proton flow battery has been adopted to reduce the number of separate components and to achieve a higher round-trip energy efficiency, and gravimetric and volumetric energy density [19]. Several works are available in the scientific literature but all of them underline the need of developing safer and efficient hydrogen storage system with acceptable volumetric energy densities.…”

Wind and solar energy have a variable and intermittent nature, a characteristic which forces fossil fuel thermal power plants to be used as backup units for grid stabilization. The development and installation of large-scale cost-effective energy storage systems is necessary to adapt electricity generated by renewables to the users' demand. But, the installation of conventional energy storage can add new capacity and further reduce the thermal power plants operational utilization factor. For these reasons, Integrated Energy Storage Systems need to be developed and installed. Pumped Thermal Electricity Storage (PTES) is an emerging technology which can offer a significant contribution to future large-scale electric storage applications. It is based on a high temperature heat pump cycle, which transforms electrical energy into thermal energy and stores it inside two thermal reservoirs, matched with a thermal engine cycle, which converts the stored thermal energy back into electrical energy. The thermal energy is stored as sensible heat in man-made reservoirs, one hot and one cold. In the present work, a detailed analysis of the available PTES configurations is presented underlining advantages, drawbacks and future development. Then, an innovative integrated energy storage unit is presented and compared with the existing ones.

“…Meanwhile, it overcomes the unneglectable difficulties during hydrogen production, distribution and storage. [8,13,14] Compared with the Metal/O 2 battery such as Zn/O 2 or Fe/O 2 battery, the innovative MH/air system deems to exhibit a relatively long lifetime and high charging efficiency because of the excellent electrochemical property of hydrogen storage alloys. [4,15] Another innovative feature of the MH/air system is that it permits a new battery can be regenerated in two different ways, namely, by gas-solid hydrogenation charging and by electrochemical charging.…”

“…In order to solve these problems, a solid polymer electrolyte is considered to replace the conventional KOH electrolyte [6].The battery with solid polymer electrolytes normally has some advantages such as reliability, safety and ease of cell designing compared with those using the conventional liquid electrolyte [7].And in 2013, Andrew J. [8] has proposed and investigated proton flow battery which is similar to MH/O 2 using Nafion as the electrolyte. Their work focus on the contrast between the new system and the conventional hydrogen cycle including hydrogen production by electrolysis, hydrogen storage and application.…”

Abstract.A solid polymer electrolyte metal hydride (MH)/oxygen cell using La 0.78 Ce 0.22 Ni 3.73 Mn 0.30 Al 0.17 Fe 0.50 Co 0.30 in the anode and Nafion as electrolyte is described and investigated experimentally. In this work, the discharge performances of the cell are compared in two charging ways, namely, electrochemical and gas-solid hydrogenation. The specific discharge capacityby gas-solid hydrogenation method is about 59.3mAh·g -1 , while almost few specific discharge capacityis obtained by electrochemical method in this work. The cell is characterized by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM) analyses. And the ex-situ XRD results of the cell charged by gas-solid hydrogenation method show that an electrochemical reaction between hydrogen and oxygen does happen, and little observable side reaction occurs. Moreover, the stability of the MH electrode depending on various relative humidity is investigated. The results indicate that solid-state MH/O 2 cell using Nafion as electrolyte is technically feasible, while the control of the water content during charge/discharge processes and the catalyst loading must be the key points. More than that, further researches are still required to enhance both charge/discharge capacity and reversibility.
