As illustrated, some facilities may use hydrogen 108 produced by a steam methane reformer 112, an external green hydrogen provider 114, or an electrolysis system 116. To coordinate the supply of hydrogen 108, facility 100 may include a controller 117 to regulate the supply of hydrogen 108 for the hydrogenation reactor 102 by the multiple sources 110.
  • the controller 117 may be communicatively coupled with sensors (e.g., thermometers, barometers, flow meters) or actuators (e.g., valves, heating/cooling systems, pressurizers) across the facility 100.

  • the hydrogen storage system 126 may be composed of high-pressure hydrogen tanks. If the hydrogenation reactor 102 has a peak production requirement that demands an amount of hydrogen 108A that exceeds the instant capacity for production of the electrolysis system 116, the hydrogen storage system 126 may be used to regulate the amount of hydrogen 108A provided to the hydrogenation reactor 102.
  • the hydrogen reactor 102 may produce some water 109 as a byproduct of the hydrogenation reaction.
  • the water 109 may be recycled into the electrolysis system for production of hydrogen 108A.
  • the amount of water 109 generated by the hydrogenation reactor will, ordinarily, be less than the amount of water demanded by the electrolysis systems and, therefore, an external water supply may be needed.
  • the efficiency of the process may allow for recycling of more than 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, or 98% of the water. This allows for a process that saves on water extracted from the vicinity of facility 100.
