Deuterium Refinery

How to use it

Deuterium per hour and fuel storage · its ceiling is set by Deuterium Synthesis

Each level increases passive Deuterium production and the amount that can be stored. Deuterium fuels fleet launches; research the next Deuterium Synthesis level when the Refinery reaches its level ceiling.

Requirements & connections

The local Command Core must reach at least the level you want to build. An earlier queued Core upgrade can meet this requirement.

Deuterium Synthesis must also permit the new level.

Upgrades use this planet’s Construction queue and resources in its Store. Resources waiting in the Works cannot pay. Keep enough stock for fuel and defence. Read order queues for timing and cancellation losses.

Reference values

Each row is the separate cost to reach that level. Local levels and research affect timers and capacities. Research timing uses the capital’s Command Core.

The table shows reference levels, not a universal building cap. The Hangar has its own fixed top; other local buildings obey the Core, and Deuterium Refinery also obeys Synthesis. Production rows exclude satellites and temporary effects.
