Project Specific Requirements: Elements for developing energy storage specific project requirements include ownership of the storage asset, energy storage system (ESS) performance, communication and control system requirements, site requirements and availability, local constraints, and safety requirements.
Designing resilient systems: although it is impossible to design for any scenario, energy storage systems should be designed to withstand common and uncommon environmental hazards in the areas they will be deployed.
The operational life of an energy storage system is a tricky concept to define generally, but it typically refers to how long a system is able to operate before degradation prevents the system from safely and reliably performing its objectives.
An economic analysis of energy storage systems should clearly articulate what major components are included in the scope of cost.

In principle, energy is stored electrochemically via two processes known as the faradaic and non-faradaic processes. The faradaic process is also known as the direct method, in which electric energy is stored by converting it into chemical energy via the oxidation and reduction of an electrochemically active material.
The complexity of modern electrochemical storage systems requires strategies in research to gain in-depth understandings of the fundamental processes occurring in the electrochemical cell in order to apply this knowledge to develop new conceptual electrochemical energy storage systems.
In electrode materials, chemical energy is stored in the chemical bonds between elements, and is referred to as chemical potential. During an electrochemical reaction, chemical energy is converted into electric energy by the conversion of a material with high bond energy to one with low bond energy.
Energy storage (ES) resources can improve the system's power balance ability, transform the original point balance into surface balance, and have important significance for ensuring the low-carbon safe operation of new power systems.
Typically, based on differences in regulatory policies and electricity price mechanisms at different times, the operation models of energy storage stations can be categorized into three types: grid integration, leasing, and independent operation.
With the expansion of the energy storage market and the evolution of application scenarios, energy storage is no longer limited to a single operating mode. Depending on the location of integration, many countries have gradually developed two main market operating models for energy storage: front-of-the-meter (FTM) and behind-the-meter (BTM).
Energy storage configuration models were developed for different modes, including self-built, leased, and shared options. Each mode has its own tailored energy storage configuration strategy, providing theoretical support for energy storage planning in various commercial contexts.
Despite the extensive research on energy storage configuration models, most studies focus on a single mode (such as self-built, leased, or shared storage), without conducting a comprehensive analysis of all three modes to determine which provides the best benefits for new energy plants.
The energy storage configuration model in the shared mode is as follows. The upper game leader is the energy storage station, and the objective function maximizes the revenue: $$max C_ {share,leader} = sumlimits_ {i} {C_ {i,service} } - C_ {investor}$$
New energy power plants can implement energy storage configurations through commercial modes such as self-built, leased, and shared. In these three modes, the entities involved can be classified into two categories: the actual owner of the energy storage and the user of the energy storage.

Electrical energy can be stored mechanically (e.g. pumped storage, compressed air storage), electrochemically (classic battery), chemically (e.g. conversion of electricity into hydrogen/methane),. The Climate and Energy Fund launched the “Storage System Initiative” as early as 2015, aimed at collecting substantial information on storage. > Direct and indirect use of electricity and heat accumulators by energy suppliers in order to optimise the overall system > Use of battery storage systems for peak load reduction in industries >.
