Deuterium Storage

In brief: “Deuterium Storage” — a building of the “Resources & Storage” category in Xterium, available from the start of the game, maximum level — 35.

(data current as of 2026-05-22, game version 2.12.7)

This module is designed to store newly synthesized deuterium. After processing in the synthesizer, deuterium is pumped through pipes into the reservoir. Each new level of storage increases the total capacity. Once over the critical mark, the synthesizer is turned off to prevent the tank from breaking.
