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, ordered by fuel value:

Solid fuel.png
Solid fuel		 12 MJ 0.96 MJ per unit of crude oil2, or
8.7 MJ per coal3		 600 MJ 120% 105% 272.2 km/h (~75.6 m/s)
Rocket fuel.png
Rocket fuel		 100 MJ 0.8 MJ per unit of crude oil2 1 GJ 180% 115% 298.1 km/h (83 m/s)
Nuclear fuel.png
Nuclear fuel		 1.21 GJ 9.68 MJ per unit of crude oil2, and
40.89 MJ per uranium ore4		 1.21 GJ 250% 115% 298.1 km/h (83 m/s)

(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.

Other fuel types

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

Item Fuel type Fuel value Fuel value
per stack		 Consumed by Consumption rate
(watts)		 Consumption rate
(items)
Uranium fuel cell.png
Uranium fuel cell		 Nuclear fuel 8 GJ1 400 GJ
Nuclear reactor.png
Nuclear reactor		 40 MW 1 per 200s
Thruster fuel.png
Thruster fuel		 Fluid2 50 kJ
Thruster.png
Thruster		 0.3 MW - 6.0 MW 6/s - 120/s
Thruster oxidizer.png
Thruster oxidizer		 Fluid2 50 kJ

Bioflux.png
Bioflux		 Food 6 MJ 600 MJ
Captive biter spawner.png
Captive biter spawner		 100 kW 1 per 60s

(1) This is 507 MJ per raw uranium ore assuming that all U-238 is enriched, all depleted uranium fuel cells are reprocessed, and there is no reactor neighbor bonus.

(2) 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.
