Fuel can be inserted into burner devices and burned to power them. Different fuels provide different amounts of energy, measured in megajoules (MJ).

Burnable fuel

The most common fuel type is burner fuel.

This is a list of all items usable as fuel in burner devices:

(1) For the purposes of in-game speed display, the game assumes 1 tile = 1 meter. I.e., a train on basic fuel travels at 72 tiles per second at full speed, and so on.

(2) This assumes all crude oil is processed completely into solid fuel using advanced oil processing and heavy oil cracking as intermediate steps, but not light oil cracking. More efficient methods are possible; in practice, the petroleum gas is more likely to be used for something other than solid fuel.

(3) Using coal liquefaction and heavy oil cracking, converting all light oil and petroleum gas into solid fuel. Does not include energy requirements of refining/mining.

(4) This assumes the "cost" is what you would have gained if you planted the seeds and harvested the grown plant, i.e. 50 yumako or jellynut.

(5) Fuel value per raw for spoilage varies a lot on the item spoiled and if they were made using the biochamber's 50% base productivity. 250 kJ assumes spoilage directly from yumako or jellynut crops. This is can go as high as about 2.43 MJ per crop using nutrients from bioflux (60 nutrients from 4.16 yumako and 1.66 jellynuts with 3.21 nutrients spent running biochambers).

Other fuel types

These fuels are consumed by specific entities and cannot be placed into standard burners.

(1) Thruster fuel and oxidizer have a fuel value but technically do not have a fuel type. Since they can only be consumed by thrusters which require specific fluids, they are effectively their own fuel types.

Consumption

The following formula can be used to find how long a fuel will last in a device: Burn time (s) = Fuel value (MJ) ÷ Energy consumption (MW)

Trivia

  • Though the top speeds given by solid fuel, rocket fuel and nuclear fuel are presented as +5%, +15% and +15% respectively, this seems to only be true for trains. The top speeds for cars and tanks are instead approximately +9.5%, +34% and +58% respectively when these fuels are used.

History

  • 0.15.0:
    • Fuel type affects vehicle acceleration and top speed.
