Clean hydrogen production through the sulfur-iodine cycle

A system for producing hydrogen, the system comprising:

• a thermally insulated chamber comprising:
• a sidewall formed of thermally insulative material;
• heating elements embedded in the sidewall, wherein the heating elements are coupled to an intermittent power source, and the heating elements heat an interior of the thermally insulated chamber responsive to electrical power from the intermittent power source;
• an inlet port for receiving sulfuric acid from a sulfur-iodine chamber;
• a first outlet port for piping sulfur dioxide into the sulfur-iodine chamber;
• and
• a second outlet port for piping hydrogen and water into a water condenser;
• and
• a controller that controls a flow of electrical power from the intermittent power source to the heating elements based on an interior temperature of the thermally insulated chamber;
• wherein the thermally insulated chamber is designed to impede a decay of the interior temperature for an interval of time that the intermittent power source is unavailable, such that the interior temperature remains at or above a threshold temperature sufficient to decompose the sulfuric acid into the sulfur dioxide, oxygen and hydrogen for a sulfur-iodine cycle over a discharge time.
