This mod adds a new vehicle fuel for each of the planets Vulcanus, Fulgor and Gleba. Each fuel is broadly comparable to Nuclear Fuel in terms of performance, but made with local materials and with some twists in the way it's made or function. Here's a breakdown of the three fuels:

Crystallic Fuel:

• Built on Vulcanus, designed for heavy cargo hauling
• Relative to Nuclear Fuel, it has increased top speed by 0.2 and increased acceleration by 0.1, but suffers from decreased fuel value by 100MJ and emits 10% more pollution.
• Requies Radiant Crystal intermediate, crafted inside a Foundry.

Ionic Fuel

• Built on Fulgora, designed for energy efficiency
• Relative to Nuclear Fuel, it has decreased top speed by 0.1, decreased acceleration by 0.1, but comes with increased fuel value by 200MJ and emits 20% less pollution.
• Requires Molecular Ionizer intermediate. When burned, Ionic Fuel leaves behind a Spent Molecular Ionizer.
• Spent Molecular Ionisers can be refurbished inside an Electromagnetic Plant.

Biomass Fuel

• Built on Gleba, designed for sustainability.
• It's identical to Nuclear Fuel, except its emissions are decreased by 60%.
• Requires Necrotising Bacteria to craft. Spoils into Necrotising Bacteria after 10 hours. Leaves behind Necrotising Bacteria when burned.
• Necrotising Bacteria can be bred from other Bacteria and Pentapod eggs, crafted inside a Biochamber.
• Necrotising Bacteria is never actually lost in the fuel-burning process. Burnt fuel returns as much bacteria as was used to craft it.
• Necrotising Bacteria decays in 1 hour, causing a large acid damage explosion which can affect player-made structures and deals a substantial amount of damage.
• Necrotising Bacteria cannot be burned as fuel. To get rid of it, it must be burned to carbon inside a Furnace.

Mod Settings:

• Energy Modifier - scales the energy difference between Planetary Fuels and Nuclear fuel. This affects both increases and decreases.
• Movement Modifier - scales the acceleration and top speed differences between Planetary Fuels and Nuclear fuel. This affects both increases and decreases.
• Pollution Modifier - scales the pollution difference between Planetary Fuels and Nuclear fuel. This affects both increases and decreases
• Add Burnt Fuel Inventory - adds 1 inventory slot for burnt items to the burner power sources on boilers, furnaces, mining drills, inserters and vehicles that don't already have any. With this option disabled, Ionic and Biomass fuels will produce nothing when burned inside most entities.
