Fuel

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

Types

This is a list of all items usable as fuel in burner devices, ordered by fuel value:

Item	Fuel value	Fuel value per raw total	Fuel value per stack	Vehicle acceleration	Vehicle top speed	Train max speed
Wood	2 MJ	4 MJ per raw wood	200 MJ	100%	100%	259.2 km/h (72 m/s)1
Coal	4 MJ	4 MJ per coal	200 MJ	100%	100%	259.2 km/h (72 m/s)
Solid fuel	12 MJ	0.96 MJ per unit of crude oil2	600 GJ	120%	105%	272.2 km/h (~75.6 m/s)
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	1.21 GJ	9.68 MJ per unit of crude oil2 1.21 GJ per Uranium-235	1.21 GJ	250%	115%	298.1 km/h (83 m/s)
Uranium fuel cell	8 GJ3	507 MJ per uranium ore4	400 GJ	Unusable	Unusable	Unusable

⁽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 the 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⁾ This fuel type can only be used in a nuclear reactor. Unlike other fuel types, it cannot be placed into standard burners.

⁽⁴⁾ Assuming that all U-238 is enriched, all used up cells are reprocessed, and there is no reactor neighbor bonus.

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 +0.095%, +1.34% and +1.58% respectively when these fuels are used.
