Abstract:
1. A solid oxide redox flow battery comprising: a battery cell and redox material in fluid communication with one another, the redox material comprising a porous structure comprising a metal and carbon, the battery cell being configured to operate between a fuel cell mode and an electrolysis mode; the redox material being configured to receive an inert gas during an initial heating process resulting in removal of gas products including CO and CO wherein the redox material being further configured to receive steam during the fuel cell mode resulting in oxidation of the metal to form the metal oxide and production of hydrogen, the hydrogen being capable of flowing to the battery cell, the battery cell being configured to electrochemically oxidize the hydrogen during the fuel cell mode to generate steam and electricity; the redox material being further configured to receive hydrogen produced from the battery cell during the electrolysis mode resulting in reduction of the metal oxide to form the metal and recharge of the redox material.
