A method for generating a metallic particle slurry in a regenerator, the method comprising the steps of: (a) generating metallic particles on a surface of a cathode by applying a forward current for a forward current period; (b) displacing the metallic particles from the surface of the cathode by applying a displacement force for a displacement period; (c) dissolving residual metallic particles by applying a reverse current for a reverse current period; (d) providing a plurality of regenerator cells; and (e) establishing an airlock by isolating aqueous electrolyte between cavities of regenerator cells.

Apparatus, systems and methods for high efficiency metal particle regeneration

Systems and methods for energy storage system are provided. The system includes a particle regeneration subsystem for applying electrical energy to regenerate metallic particulate fuel; a fuel storage subsystem for storing metallic particulate fuel, the fuel storage subsystem in fluid communication with the particle regeneration subsystem; and a power generation subsystem for producing electrical energy from the metallic particulate fuel, the power generation subsystem in fluid communication with the fuel storage subsystem; a bearer electrolyte for transporting the metallic particulate fuel through the particle regeneration subsystem, the fuel storage subsystem and the power generation subsystem; and a control unit configured to independently control flow of the bearer electrolyte between the particle regeneration subsystem and the fuel storage subsystem, and the fuel storage subsystem and the power generation subsystem.

Systems and methods for fuel cells energy storage and recovery

A regenerator cell for regenerating metallic particles is provided. The regenerator cell includes: a housing for containing a quantity of electrolyte; an anode; a cathode; a cavity at least partially defined by the housing, the cathode and the anode; an inlet port for supplying electrolyte to the cell, the inlet port in fluid communication with the cavity; and an outlet port for expelling electrolyte, particles and/or gas from the cell, the outlet port in fluid communication with the cavity.

Systems and methods to overcome limited efficiency of energy storage and recovery processes in fuel cells are provided. The system include a particle regeneration subsystem for applying electrical energy to regenerate metallic particulate fuel; a fuel storage subsystem for storing metallic particulate fuel, the fuel storage subsystem in fluid communication with the particle regeneration subsystem; and a power generation subsystem for producing electrical energy from the metallic particulate fuel, the power generation subsystem in fluid communication with the fuel storage subsystem; a bearer electrolyte for transporting the metallic particulate fuel through the particle regeneration subsystem, the fuel storage subsystem and the power generation subsystem; and a control unit configured to independently control flow of the bearer electrolyte between the particle regeneration subsystem and the fuel storage subsystem, and the fuel storage subsystem and the power generation subsystem.
