Abstract
System and method for energy storage and recovery is described. More particularly, system and method using tungsten based materials to electrochemically store and recover energy is described. In certain embodiments, the system includes a reversible solid oxide electrochemical cell (RSOEC) having a porous cathode, a porous anode, and an electrolyte capable of transporting oxygen ion. The system further includes a reactor comprising tungsten, tungsten oxide, or combinations thereof. To store the energy, the RSOEC is capable of receiving electricity to electrolyze HO to generate Hand Oand the reactor is operably connected to the RSOEC to receive the generated H2 and convert tungsten oxide to tungsten thereby storing electrical energy. To recover the energy, reactor is capable of receiving HO to convert tungsten to tungsten oxide and generate Hand the RSOEC is operably connected to the reactor to receive the generated Hand generate electrical energy.
