1. A system including:
a storage medium configured to store thermal energy generated by a conversion of input electricity from an input energy supply, the input energy supply having intermittent availability;
a fluid movement device configured to move fluid in contact with the storage medium to heat the fluid to a specified temperature, the fluid comprising oxygen and nitrogen, wherein the fluid movement device is configured to provide the fluid at the specified temperature to a solid oxide cell electrolysis system that converts water to hydrogen and enriches the fluid with oxygen; and
a steam generator configured to, using the fluid received from the electrolysis system, convert input feed water into steam.
 
27. A method for producing steam from renewable electricity, including the steps of:
converting electricity derived from a renewable energy source into heat;
supplying the heat to a thermal storage medium;
circulating a fluid through the thermal storage medium to heat the fluid to a temperature sufficient to convert water into steam;
providing the heated fluid to a solid oxide electrolysis system which is configured to produce hydrogen from water and enrich the fluid with oxygen;
providing a steam generator with a supply of input feed water; and
directing the oxygen-enriched fluid from the electrolysis system to pass through the steam generator configured to generate steam from the input feed water.
