As a type of energy storage technology applicable to large-scale and long-duration scenarios, compressed carbon dioxide storage (CCES) has rapidly developed. The CCES projects, including carbon dioxide battery in Italy and carbon dioxide storage demonstration system in China, have also been completed.

For liquid carbon dioxide energy storage (LCES) technology, CO 2 is stored as liquid phase in both HP and LP sides of the system, which has high energy storage density and strong operation stability.
On the contrary, during the energy storage process, carbon dioxide is gradually compressed, and the state of the workinguidchangesfromtranscritical tosupercritical; during the energy release process, carbon dioxide is gradually expanded, and the state of the working uid changes from supercritical to transcritical.
Furthermore, based on the storage methods of carbon dioxide, CCES is subdivided into seven types of storage systems: gas-to-gas, gas-to-supercritical, gas-to-liquid and liquid-to-liquid, among others. The research progress of each type of system is discussed. Their performance is compared in tabular form.

Porous carbon materials have emerged as a promising class of materials for energy storage applications due to their unique properties, including high surface area, tuneable pore structure and excellent electrical conductivity.
This review summarizes progress in the use of porous carbons in different energy storage devices, such as lithium-ion, lithium-oxygen, lithium-sulfur, and lithium-metal batteries for anode protection, sodium-ion and potassium-ion batteries, supercapacitors and metal ion capacitors.
Summary of properties of porous carbon in energy applications. Increases charge storage in capacitors and batteries; enhances ion adsorption in hydrogen storage; improves catalytic efficiency. Optimizes ion storage, gas adsorption, and electrochemical reaction sites for energy conversion and storage.
To enhance the quality of porous carbons for energy storage applications, various techniques have recently been developed, including the pyrolysis of conjugated copolymers, block copolymers. Furthermore, the impact of synthesis parameters, activation agent, temperature and time on the resulting pore structure was discussed.
This material is particularly well-suited for applications in supercapacitors, lithium-ion batteries, and other energy storage systems. The porous carbon material fabricated from these two waste streams boasts a wealth of pores and an exceptional specific surface area (1,768 m2 g-1), which in turn confers superior electrochemical performance.
Porous carbon materials can store and release thermal energy using different mechanisms, with the most prominent being adsorption and desorption. In this process, porous carbon materials adsorb heat at high temperatures. The heat is stored as chemical energy at the surface of the material. When the system is cooled, the adsorbed heat is released.

Their analysis suggests that refurbishing and selling a fraction of batteries at the end of their lives, while recycling the remainder, minimizes the economic risk of recycling. This strategy has relatively high, more stable profits that are more consistent regardless of market conditions..

Although academic analysis finds that business models for energy storage are largely unprofitable, annual deployment of storage capacity is globally on the rise (IEA, 2020). One reason may be generous subsidy support and non-financial drivers like a first-mover advantage (Wood Mackenzie, 2019).
Building upon both strands of work, we propose to characterize business models of energy storage as the combination of an application of storage with the revenue stream earned from the operation and the market role of the investor.
Our review shows that a set of commercially available technologies is sufficient to perform all identified business models. We also find that matches appear to have approached a tipping point toward profitability. Yet, this conclusion only holds for matches that either have been examined since 2017 or entail multiple business models.
The literature on energy storage frequently includes “renewable integration” or “generation firming” as applications for storage (Eyer and Corey, 2010; Zafirakis et al., 2013; Pellow et al., 2020).
Bolder approaches could include the design of special electricity tariffs for investors in a consumer role that unlock the ability of energy storage to mitigate unexpected demand peaks (Peak Shaving) and balance conventional demand patterns (Consumption Arbitrage) (Fridgen et al., 2018).
Where a profitable application of energy storage requires saving of costs or deferral of investments, direct mechanisms, such as subsidies and rebates, will be effective. For applications dependent on price arbitrage, the existence and access to variable market prices are essential.
