In one recorded playtest factory, an ice facility supplied premade hydrogen cells by ship. The receiving dock fed those cells into the station reactor. You can use that arrangement as a model once your own build has the equipment to support it.
Prove the reactor can receive fuel
Start with a small supply and check that it reaches the reactor. Watch the station's power state with a machine running. Verify that the fuel handoff works before making the factory depend on a scheduled delivery.
Give the fuel shipment a clear route
The playtest player used a separate facility to prepare the cells. A ship delivered them to a dock at the consuming station. Keep the fuel path easy to trace from that dock to the reactor so you can find a missing handoff.
Check where an interruption starts
If the station loses power, see whether the supplier still makes cells, whether the ship delivers them, and whether the reactor receives them. That sequence distinguishes an empty ship from an interrupted station-side feed.
See Main Sequence on Steam for the official game information.
FAQ
Which fuel did the playtest arrangement use?
The player's station reactor received premade hydrogen cells.
Do I need two stations to get started?
The separate supply facility was part of that playtest setup. Start by proving that your reactor can run with the fuel and equipment in your build.
When should I automate the delivery?
After you have confirmed that the receiving station can use a test shipment and that the delivery route can repeat.
