[[Fuel]] is every item that can be burned to provide energy to a burner structure. The [[Items]] differ in fuel value which is the provided energy portion.
'''Fuel''' can be inserted into [[burner devices]] and burned to power them. Different fuels provide different amounts of energy, measured in megajoules (MJ).

(*) The amount of [[Solid fuel]] per [[Crude oil]] depends on the kind of oil processing, cracking and which solid fuel recipes are used; 20 MJ are achieved by using [[Advanced Oil Processing]] and [[Heavy Oil Cracking]], being the most efficient, while 9.375 MJ are achieved by using [[Basic Oil Processing]], [[Heavy Oil Cracking]] and [[Light Oil Cracking]], being the least efficient way.

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:

Pentapod egg		 5 MJ 5 MJ per egg 100 MJ 1 GJ6 100% 100% 259.2 km/h (72 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.

(4) This assumes the "cost" is what would have been gained if all seeds were planted and the grown plant was harvested, 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).

(6) These products spoil, and thus are usually not suitable fuels to move between planets.

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		 Nuclear fuel 8 GJ 400 GJ
Nuclear reactor		 40 MW 1 per 200s
Fusion power cell		 Fusion fuel 40 GJ 2 TJ
Fusion reactor		 100 MW 1 per 400s
Thruster fuel		 Fluid1 50 kJ
Thruster		 0.3 MW - 6.0 MW 6/s - 120/s
Thruster oxidizer		 Fluid1 50 kJ
Thruster		 0.3 MW - 6.0 MW 6/s - 120/s
Nutrients		 Nutrients 2 MJ 200 MJ
Biochamber		 500 kW 1 per 4s
Bioflux		 Food 6 MJ 600 MJ
Captive biter spawner		 100 kW 1 per 60s

(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.
