Acceptable Ship Fuel

These items can be used to refuel the player's ship. They are loaded into the Fuel Hatch. Fuel is spent when traveling to other stars (travel within the system is free), and the cost is affected by discounts from Crew and Fuel Purifiers up to a maximum of 99% reduction.

Purifiers reduce fuel cost by a flat amount, stacking up to 4 purifiers. They can be placed anywhere in the ship to gain their benefits.

Fuel cost reductions from crew stack infinitely, but have diminishing returns.

Trivia

 * In vanilla Starbound, only Erchius was valid fuel. Most types of fuel in FU can be produced without visiting the Moon, and some fuels (such as Hydrogen or Energiflower) can be easily automated.
