Deuterium
Material, Fuel
A stable isotope of hydrogen. Rarely exists under natural conditions. Most of them come from the reprocessing of hydrogen and the collection from the Gas Giant.

Summary
Deuterium is stable heavier isotope of Hydrogen. Rarely exists under natural conditions. Most comes from the reprocessing of hydrogen and collection from Gas Giants via Orbital Collectors.

Player Tips & Tricks
- Using Fractionators to produce Deuterium is roughly 2.5 times more energy efficient (using Mk.III Conveyor Belts) than Particle Colliders. It takes more space to set up but works in a simple loop (with a buffer liquid storage slowly refilled with Hydrogen). A Fractionator processing Hydrogen piled four times using the Automatic Piler consumes 1.375 times as much energy per Deuterium as a normal Fractionator, with throughput closer to the Particle Collider's Deuterium production, and it can be a middle ground on energy usage and space while retaining the 1:1 Hydrogen to Deuterium conversion.
