Astroneer Wiki

Hello all editors and users of the Astroneer Wiki! We are in the process of updating and switching over to use the new Fandom Desktop skin on the wiki. There will be many changes over the coming days, but the main goal is to keep the wiki feeling the same, as much as we can! If you notice any issues once the swap is made, please post them to the Admin Noticeboard so we can address it right away. We are also going to be completing the update to the Astroneer Wiki:Style guide, so there is a more up to date guide on how to style the wiki going forward.

Carbon is a refined resource in Astroneer.


Output Input Module
Carbon Organic Smelting Furnace


Carbon is used to craft the following items:

Module Output Input
Chemistry Lab Plastic Compound
Tungsten Carbide Carbon
Explosive Powder Carbon x2
Steel Carbon

Carbon can be used with a Medium Generator to produce Power.

Carbon gives 75 bytes when placed in a Research Chamber.


Carbon provides more power overall than a nugget of Organic.

  • Organic fuels a Small Generator for 120 seconds at 2U/s, which produces 240 Units.
  • Carbon, placed in a Medium Generator, runs for 120 seconds at 9U/s and produces 1080 Units.
  • Smelting Organic into Carbon only takes 60 Units in a Smelting Furnace, and consequently raises its effective power output by 780 Units.
  • Using a Soil Centrifuge takes 121.5 Units to make 4 or 8 Organic. Per Organic power cost is 30.4 for 4 and 15.2 for 8.

When planning for long trips, Carbon has the highest consumable power yield per single T1 slot of any item in the entire game, with a few exceptions;

  • The tier 2 slot that a Medium Generator takes up is effectively 24 tier 1 slots that could be used by a Medium Storage Silo to hold Organic and Small Generators.
  • Consequently, it's possible to carry more energy per storage space used by placing Organic instead of Carbon if space is limited.
  • The ratio flips above 12 spaces used; 12 T1 spaces worth of Organic or Carbon produce almost exactly the same amount of power, including the overhead of the space the generator takes up. An easy way to remember is that if you must carry more than 12 Organic for portable power, you will be able to store more total energy by using a Medium Generator instead. ;)


  • In Update 0.10.1 Coal was removed from the game and replaced with Carbon.
  • Coal's purpose in the game was as a solid fuel which powered the Medium Generator, even though it was generally thought to be superfluous in the main game flow; As a trade resource it was as valuable as titanium, making it nonetheless exciting to discover.
