Hydrogen is one of the Resources in the game Oxygen Not Included. It is an unbreathable Gas that is extremely light and will rise above all other gases. This means that it will settle at the top of rooms and other open areas.

Hydrogen can easily be density-separated with a reverse funnel at the top of your base, and collected with a pump when levels get too high.

Production[]

Usage[]

In the current build of the game, Hydrogen has several uses:

  • It can be burned in the Hydrogen Generator to produce 800 W of power. See Hydrogen Generator#Practicality.
  • It can be condensed into Liquid Hydrogen to serve as a rocket fuel for Hydrogen Engine, the most powerful type of rocket-engine. Condensation of Hydrogen requires a dedicated cooling setup using the most advanced materials.
  • It can be stockpiled and utilized as heat transfer agent due to its high thermal parameters.
  • Dreckos and Glossy Dreckos require spending time in Hydrogen atmosphere to grow their scales of Reed Fiber or Plastic.
  • It is one of the best gasses to use with the Thermo Regulator because of its high Specific Heat Capacity, high Thermal Conductivity and the fact that remains in the gas state until extremely low temperatures. That said, for most heat transfer applications the Thermo Aquatuner is more practical.
    • Extreme temperatures, where most liquids would boil, would make the use of Hydrogen as a working fluid practical. Furthermore, with the use of Radiant Gas Piping and how Thermal Conductivity works, the properties of Hydrogen - or any other gas for that matter - is moot when heat exchange is the goal.

Cooling[]

Hydrogen can be used to power the Anti Entropy Thermo-Nullifier, which produces -80 kDTU/s at the cost of only 10 g/s of Hydrogen. Venting extra hydrogen into the cold biome and then back, or using natural convection, will quickly cool your base.

Locking Wheezeworts in a room with a Hydrogen atmosphere, increases their cooling efficiency.

Thermo Regulators can be put in the same room, it will prevent them from overheating, while they are used to cool other gases in your base (like your oxygen).

More power-efficient setup, that generates consistent, controlled temperature, will include Mechanized Airlock paired with Thermo Sensor and oil/metal buffer.
