Deuterium
Deuterium is a stored material used for construction and fleet fuel. Each station has its own stock; transporting materials or completing a delivery changes the receiving station's inventory.
Production and storage
Build a Deuterium Synthesizer to produce more. Completed levels, temperature, position, energy, resource settings and research affect the rate. Basic income is separate from mines and does not receive position bonuses.
Upgrade Deuterium Tank before production reaches capacity. Check Resource Settings for current hourly production and storage instead of relying on an old season's output table.
Spending and trading
Buildings and ships need Credits as well as materials. Research Constellation levels use RP, not direct material payments. Materials can still be needed to build the Research Labs that earn RP.
Buy or sell at the Credit Market. Purchased materials wait in My Deliveries until a pickup trip brings them home. Review the quote and keep enough cargo capacity and fuel.
Planning tips
Cold outer positions favor Deuterium. Leave enough for fleet launches, Energy Cell Factory charging and Deuterium Power Plant grid production before placing a large order. The 3.0.5 Quantum Datacenter also consumes Deuterium and Fuel Cells while earning Credits; level 1 at full output needs 10 Deuterium per hour.
Protect valuable stocks with a fleet and transport plan. Materials carried away are unavailable for local construction until they return; Credits and G cannot be loaded as cargo.
