Energy Cell Factory
Energy Cell Factories consume Deuterium to charge Fuel Cells. They do not feed the live energy grid; use Solar Plants, Solar Satellites or Deuterium Power Plants for your mines.
Requirements and operation
- Deuterium Synthesizer 5 and Fusion research 1 to construct.
- Fuel Cell Technology 1 to charge Fuel Cells.
- Deuterium, an operating factory and room in Fuel Cell storage.
At full production, output is 22 × level × 1.04^level. Energy Technology, Fusion's global energy bonus and Fusion's additional factory bonus multiply it. Research gives its initial benefit at level 1; later levels use the five-level tier and compounding progression.
Charging converts factory output at 1 Fuel Cell per 80 output, then applies Fuel Cell Technology and applicable Commerce charging bonuses. The factory slider scales both output and fuel use in 10% steps. Economy speed multiplies Deuterium cost, not direct output. Check Resource Settings for the final rates.
The underlying Deuterium use is 16 × level × 1.12^level at full production before economy speed. The factory spends available fuel only; charging slows proportionally over partly fueled intervals and stops when fuel is exhausted. A power deficit can drain Fuel Cells independently.
Storage
Finite Fuel Cell storage starts from max(5,000, maximum grid energy × 12). A factory adds:
floor((10,000 × floor(2.5 × exp(20 × factory level / 33))) / 10)
Fuel Cell Technology and Fuel Cell Reserve Banking then increase finite capacity. The bonus uses the storage-building curve, not an additional 25,000 resource-storage baseline.
Construction cost
Base material cost for target level L is the level-1 amount × 1.8^(L − 1), rounded to the nearest whole resource before applicable discounts.
| Resource | Level 1 | Level 5 |
|---|---|---|
| Metal | 900 | 9,448 |
| Crystal | 360 | 3,779 |
| Deuterium | 180 | 1,890 |
Material Physics reduces material costs. Buildings and facilities also require the Credits shown in the construction quote. Use that quote for your actual price.
When to build
Build around real Fuel Cell demand: scans, gates and mission boosts. Improve Deuterium supply alongside charging capacity and avoid burning fuel for a reserve you are not using.
