Hydrogen

Hydrogen is a liquid resource in Mindustry that represents the in-game form of hydrogen. It appears as a processed fluid with low boiling point and is classified as a gas-type liquid within the game data. Hydrogen is flammable and is used in several production chains and combat roles rather than as a raw mineral; it functions in resource processing, unit production, and structure repair, and can also serve as ammunition for certain turrets.

Hydrogen's in-game physical properties are defined with middle-range thermal and flow characteristics: it has 100% flammability, 0% explosiveness, 50% thermal capacity, 50% viscosity, 50% temperature, and a boiling point value listed as -1. These values make it highly combustible but not explosive, and give it moderate handling characteristics in piping and cooling mechanics. In the game data it is identified as liquid ID #5 with the internal English ID "hydrogen" and a characteristic color used by UI elements.

Practically, Hydrogen is integrated into several factory and production workflows. It is consumed by machines that refine or synthesize advanced materials, and it is used when producing certain units and when repairing structures. Because it is flammable, Hydrogen can interact with damage and environmental systems in ways that other inert fluids do not; keep this in mind when routing pipes near heat sources or weapon fire. Hydrogen can also be fed into compatible turrets as ammunition to provide specialized firing effects where supported by the game’s turret definitions.

Real-world notes reflected in the game's trivia: real hydrogen exists as the diatomic gas H₂ at standard conditions, it serves as an effective coolant because of high thermal conductivity and plays a role in industrial chemistry such as ammonia production, and it is historically known for its flammability (notably the Hindenburg disaster). These real-world properties are echoed in the game by Hydrogen’s high flammability value.

• Use Hydrogen in production chains that require gaseous feedstock for unit manufacturing or building repair modules.
• Route Hydrogen piping carefully to minimize exposure to heat sources and weaponfire due to its full flammability.
• Hydrogen can serve as turret ammunition in some designs; check turret definitions or in-game building descriptions to confirm compatibility.
• Its moderate thermal and flow stats make it straightforward to pump and cool compared with highly viscous or extreme-temperature fluids.
