Targets are for a complete system, including tank, material, valves, regulators, piping, mounting brackets, insulation, added cooling capacity, and all other balance-of-plant components. All capacities are defined as usable capacities that could be delivered to the fuel
Energy storage systems (ESSs) are the key to overcoming challenges to achieve the distributed smart energy paradigm and zero-emissions transportation systems.

A Shared energy storage system (SESS) has the potential in reducing investment costs, increasing the rate of renewable energy consumption, and facilitating users [6]. In reference [7], the
The useful life of electrochemical energy storage (EES) is a critical factor to system planning, operation, and economic assessment.
