“…Although, using CO2 maximizes the volume of the vessel that can be utilized for energy storage, the pressure is restricted to approximately 60 bar, depending on the ambient temperature. This pressure is much lower than the existing vessel's maximum allowable working pressure of 140 bar [21]. The goal of this study is to determine whether using a mixture of air and CO2 can result in higher ED than using air alone.…”

This paper demonstrates a new method by which the energy storage density of compressed air systems is increased by 56.8% by changing the composition of the compressed gas to include a condensable component. A higher storage density of 7.33 MJ/m3 is possible using a mixture of 88% CO2 and 12% N2 compared to 4.67 MJ/m3 using pure N2. This ratio of gases representing an optimum mixture was determined through computer simulations that considered a variety of different proportions from pure CO2 to pure N2. The computer simulations are based on a thermodynamic equilibrium model that predicts the mixture composition as a function of volume and pressure under progressive compression to ultimately identify the optimal mixture composition (88% CO2 + 12% N2). The model and simulations predict that the optimal gas mixture attains a higher energy storage density than using either of the pure gases.

“…1). A great number of researches have been devoted to study the heat transfer behaviors through monitoring the evolution of gas temperature [36,37,27] and by implementing various techniques to enhance the heat transfer [26,33]. Few studies have focused on the flow patterns and their transition, showing that the fluid flow hydrodynamics are rather complex and difficult to predict especially when coupled with heat transfer [36,38].…”

Compressed air energy storage systems (CAES) have demonstrated the potential for the energy storage of power plants. One of the key factors to improve the efficiency of CAES is the efficient thermal management to achieve near isothermal air compression/expansion processes. This paper presents a review on the Liquid Piston (LP) technology for CAES as a timely documentary on this topic with rapidly growing interests. Various aspects are discussed including the state-of-the-art on LP projects all over the world and the trend of development, the coupled fluid flow and heat transfer during the compression/expansion operations, and different actions proposed and implemented to enhance the heat transfer inside the piston column.It has been found that LP is a promising concept for isothermal CAES. However, the complex and transient fluid flow and heat transfer behaviors inside the LP are difficult to characterize and master. To enhance the heat transfer and increase the efficiency of the compression/expansion processes many approaches have been tested including liquid spray, wire mesh, porous media, optimal trajectory, hollow spheres and optimal geometry of the piston column. Numerous Nusselt number's empirical correlations have also been proposed to estimate the

“…If available, waste heat from the operation of nearby systems (i.e., an air-conditioning unit) can be used to increase the air pressure and outflow of liquid from the vessel, amplifying the system's energy production capability and round-trip efficiencies. Additionally, the liquid can be composed of water or some hydraulic oil, with the latter favored because it would remove the additional lubrication requirements of water-based pumped storage systems and thus increase efficiencies (Odukomaiya et al, 2018). Currently, GLIDES is economically infeasible with a large ICC of $18,000/kW (in 2015 dollars), primarily due to the costs of the pressurized tanks (Hadjerioua, 2017).…”

Report Overview: This report is designed to address barriers and solutions to modern pumped storage hydropower (PSH) development by establishing baseline project development knowledge, defining key aspects of project development, and identifying opportunities to reduce project timelines, costs, and risks. This report's scope includes post-licensing activities and excludes factors related to permitting or licensing. Context: The U.S. PSH fleet is composed of 43 projects providing the majority (95%) of utilityscale electricity storage in the US. However, only one new PSH facility has become operational in the past 20 years. Several factors contribute to diminishing PSH growth in the US, including the magnitude of project costs and financing interest during development and construction; the length of time from project investment until project revenue; permitting challenges and construction risks; competition from other storage technologies; and unrecognized energy storage valuation. Although innovative PSH concepts (including underground, small, and modular systems) have been investigated, widespread application has yet to occur. In short, the time, cost, and risk associated with modern PSH development has resulted in limited recent growth in the United States, despite the rising energy storage demand from increased deployment of variable renewable technologies. FAST Analysis and Prize: To address these challenges, the US Department of Energy's (DOE) Water Power Technologies Office initiated the PSH Furthering Advancements to Shorten Time to (FAST) Commissioning project, aimed at catalyzing new solutions, designs, and strategies to accelerate PSH development. This report uses available data from previous license applications, ongoing project cost data, and other global PSH project information based on a typical closed-loop PSH project. Key Findings: Considering baseline costs, timelines, and risks associated with PSH facilities, this report indicates that across all project development categories, civil works, including the upper and lower reservoirs and water conveyance components, and equipment, most notably the powertrain, comprise the largest portions of overall project capital costs (67% and 26%, respectively; see pie chart). Similarly, the upper and lower reservoirs, water conveyances, and transmission interconnection components require the Representative capital cost breakdown for an example PSH project
