Biofuel Block
HarvestMaterialOverview
Condensed, space-efficient fuel suitable for use in a bioreactor. Produced at the processor from a variety of source organics. Used as a crafting ingredient in Nutrient Block, requiring 1 per craft at the Fabricator. This positions Biofuel Block in the equipment progression, where crafted tools and gear expand the player's exploration range, survivability, and resource-gathering efficiency. Biofuel Block occupies the intermediate tier in Subnautica 2's crafting hierarchy, sitting between raw resources and finished equipment. Materials like this are the connective tissue of progression — without steady supply, advanced recipes stall regardless of how many blueprints you have unlocked.

Tips & Strategy
Needed for Nutrient Block (1x per craft) — collect at least 2 to allow crafting with a safety margin.
Keep Biofuel Block organized in labeled storage near your primary crafting station — maintaining an ordered inventory prevents wasted time searching for materials during urgent crafts.
All recipes using Biofuel Block are crafted at the Fabricator — store your supply near this station for maximum efficiency.
Explore different biomes systematically to discover all Biofuel Block sources — harvested organic resources often appear near specific flora or fauna, and identifying these associations makes future gathering predictable.
When gathering Biofuel Block for Nutrient Block, also collect Salt on the same trip — completing all recipe requirements in one expedition saves significant travel time.
