Description

Storing water got you down? At the expense of power, you can turn that excess water into a bunch of heat and a somewhat risky mix of Oxygen and Volatiles using the new Electrolysis Machine. Available on the existing Atmospherics kit with Air Conditioners and Filtration machines.

Usage

  1. Select Kit (Atmospherics) for placement, and change the variant to Electrolyzer.
  2. Connect liquid pipe to the Input liquid connection to transfer water into the machine.
  3. Connect gas pipe to the Output gas connection to remove the created H2 and O2.

Notes

  • H2 and O2 are produced mixed together in a single gas pipe, creating a dangerous fuel mixture that can be directly used in a furnace.
  • Higher water temperatures result in slightly higher efficiency leading to marginally higher production rates. https://en.wikipedia.org/wiki/High-temperature_electrolysis
  • The conversion rate is 1 mol H2O produces 0.5 mol O2 and 1 mol H2.
  • Assuming perfect insulation, the Electrolyzer always outputs its byproducts at 20°C. However, it is not insulated.
  • If the temperature inside the Electrolyzer reaches 300C, autoignition occurs, creating additional heat, and converting virtually all O2 and H2 inside the machine into CO2 and X. Keep this in mind on high-temperature worlds.
  • If autoignition occurs, it doesn't propagate to the gas pipe connected to the Electrolyzer, so the gas already removed is safe, provided it is insulated from further temperature increases.
  • The Electrolyzer's internal volume is generally separated from the pipe network, and it can release its content only if the machine is turned on.
