Systems and methods for local generation and/or consumption of hydrogen gas

A system for producing hydrogen gas for local distribution, consumption, and/or storage, the system comprising:

• a pyrolysis reactor coupleable to a supply of reaction material that includes a hydrocarbon, wherein the pyrolysis reactor includes one or more flow channels positioned to transfer heat to the reaction material to convert the hydrocarbon into an output that includes hydrogen gas, carbon particulates, and heat, and wherein the pyrolysis reactor is sized to receive the reaction material at a rate between 500 and 1,000,000 standard cubic centimeters per minute;
• a carbon separation system operably coupled to the pyrolysis reactor to separate the hydrogen gas the carbon particulates in the output;
• and
• a power generation component locally coupleable to the pyrolysis reactor to receive at least a portion of the output and convert the output into electrical power.
