Bioreactor (Below Zero)

View History

The Bioreactor is a Seabase Module in Subnautica: Below Zero that composts organic matter into electrical energy. It serves as a reliable power source for outposts, especially in biomes with abundant organic resources.

The Bioreactor is constructed with the Habitat Builder and composts organic matter into Energy. It is one of the default power generators available (the other being the Solar Panel). It features a 4×4 inventory grid to place organic items into; once placed, items cannot be removed. The Bioreactor breaks down any organic matter into reliable energy for Seabases.

It produces 1 energy every 1.2 seconds (50 per minute) with a maximum capacity of 500 units per Bioreactor. It can only be placed inside a Multipurpose Room or Large Room. It does not affect power in creative mode.

Overview

Bioreactors work well in biomes where organic matter is plentiful or where Solar Panels may be less efficient. It is also easy to supply a Bioreactor with fuel if one keeps an Exterior Growbed, Indoor Growbed, or Alien Containment full of fish nearby. It is also useful for disposing of any excess or spoiled flora and fauna that the player has no more need of. Egg-hatched fish in particular provide the most energy.

Thanks to its low costs and easily renewable fuel, it is perfectly suited to power outposts with low power devices like a [Battery Charger](/wiki/battery-charger) or Power Cell Charger, especially if the area lacks the requirements for both Solar Panels and Thermal Plants. But even if better sources are available, it still provides easy additional energy for heavy power consuming seabases.

Bioreactor Values

Items placed in the bioreactor will continue to generate energy up to the value listed for that item per slot that item takes up. For example, an [Arctic Peeper](/wiki/arctic-peeper) takes up one slot, so it will generate its value of energy and no more, but a Fevered Pepper takes up two slots, so it will generate its value times 2.

Databank Entry

Bioreactor Ency

On planets where organic matter is plentiful but sunlight is not, a reliable bioreactor will frequently prove the most efficient power solution.

  • May be installed in any multipurpose habitat room
  • Chemically composts organic materials, converting them into energy over time
  • Accepts all plant matter, from seeds and spores to moldy fruits and vegetables
  • Can also process animal matter (fat, muscle, eggs, etc) and some organic waste products
  • Energy production is proportionate to the calories in the organic matter
