Deuterium Tank
Overview
The Deuterium Tank stores deuterium and protects it from raiders. Deuterium is the hardest resource to produce so protecting it matters more than for metal or crystal.

Tips
Fusion Reactor Dependency
If you run a Fusion Reactor, ensure your tank is large enough to buffer several hours of consumption. A full tank keeps the reactor running through offline periods.
Fleet Fuel Reserve
Keep at least one full fleet-trip's worth of deuterium protected. Running out mid-recall is painful.
