Deuterium Refinery

Description

What it is and why you need it

Deuterium Refinery — a building from the “Resources & Storage” category in Xterium. Produces the resource deuterium. Deuterium is fleet fuel and a consumable for jumps, espionage, and fusion plants.

When to build

Unlocks once the requirements listed below are met. At level 5 it unlocks Deuterium Storage — build it right away, otherwise production will hit the storage cap and stop.

How it scales with levels

Each level raises production by roughly 1.1×. Base production: at level 1 — 5/h, at level 10 — 90/h, at level 30 — 950/h, at level 50 — 4 600/h, at level 100 — 270 800/h. Energy consumption grows in parallel: by level 100 — 233 000 units.

What to watch out for

Energy. The building consumes energy. Without it the effect drops or stops entirely.
Storage. When “Deuterium Storage” is full, production stops too. Level up storage together with the mine.

How much it mines

Production grows with each level. Here is how much the building yields per hour and how much energy it consumes at key levels:

Level 1

5/h

⚡ 3 of energy

Level 10

90/h

⚡ 80 of energy

Level 20

360/h

⚡ 400 of energy

Level 30

950/h

⚡ 1 600 of energy

Level 50

4 600/h

⚡ 17 500 of energy

Level 75

31 300/h

⚡ 68 800 of energy

Level 100

270 800/h

⚡ 233 000 of energy

Caution: without energy, production stops. If the planet lacks energy, output drops in proportion to the shortage. With each level energy consumption grows faster than production itself — keep an eye on the balance and cover the deficit in advance with a Power Plant or a Thermal Power Plant.

When the storage is full, production stops too. The produced resource has nowhere to go, and the mine halts until space frees up in storage. Upgrade Deuterium Storage together with the mine so capacity keeps up with production.

How final production is calculated

The numbers in the cards above are the base production on a server with multiplier 1, without bonuses and without planet anomalies. The final in-game value works out like this:

Total = base × server multiplier × (1 + planet bonuses in %) × (mine work percentage)

Where mine work percentage is a 0-100% slider (100% by default). If energy is short, the engine lowers this percentage by itself in proportion to the deficit.

For example: if the base production at level 30 equals X, and on the server the multiplier is 2 with a +30% metal-mining anomaly — the hourly total will be X × 2 × 1.3 × 1.0.

Build time depends on the level of the Robot Factory and the Nanite Factory, as well as any speed-ups applied. The higher these buildings, the faster.

Speeding up the build with DM: you can shorten the remaining build time for dark matter — the price depends on how much time is left. The less remaining, the cheaper.

Cost

Payback by level

How many hours of operation a building needs to pay back its construction. All resources (metal, crystal, deuterium) and production are reduced to a single equivalent at the rate: 1 crystal = 2 metal, 1 deuterium = 4 metal. The higher the level, the longer the payback, but the higher the production too.

Questions and answers

What is «Deuterium Refinery» in Xterium?

“Deuterium Refinery” — a building of the “Resources & Storage” category in Xterium, mines the resource deuterium, maximum level — 100, base production at level 1 — 5 units/hour.

At what level does the «Deuterium Refinery» building unlock “Deuterium Storage”?

At level 5 «Deuterium Refinery» unlocks access to the “Deuterium Storage” building.

What is the maximum level of the «Deuterium Refinery» building?

Maximum level — 100.

How much does «Deuterium Refinery» produce at level 100?

At level 100 «Deuterium Refinery» gives 270 800 units per hour. At level 1 — 5/h, at 30 — 950/h, at 50 — 4 600/h. This is base production on a ×1 server, without anomaly bonuses or alliance upgrades.

How much energy does «Deuterium Refinery» consume at level 100?

At level 100 «Deuterium Refinery» consumes 233 000 energy units. At level 30 — 1 600, at 50 — 17 500. If energy is insufficient, production drops proportionally to the shortage. With each level, consumption grows faster than production itself.

What happens if “Deuterium Storage” fills up?

When storage is full, «Deuterium Refinery» stops production — there is nowhere to put new resources. To avoid downtime, level up “Deuterium Storage” together with the mine.

What increases production for the «Deuterium Refinery» building?

Permanent bonus sources: Geologist, Mining Methods, Deuterium Synthesis. Senator specialization, temporary boosters from special offers, and alliance upgrades also have an effect.
