Hydrogen

Hydrogen is a gaseous resource found in the atmosphere of several planets. It is one of the basic atmospheric resources and is gathered in parts per unit rather than mined from solid terrain. The available concentration varies by planet, with reported values of 75 ppu, 50 ppu, 100 ppu, 25 ppu, and 100 ppu across the planets where it appears.

Hydrogen is used as a crafting ingredient and is also involved in progression through atmospheric resource handling. The resource can be stored in canisters, and like other gases it can be moved, carried, and processed once collected. It also has a few notable interactions that make it important to handle carefully:

• Hydrogen will explode if Dynamite goes off nearby.
• Hydrogen will also explode when placed in an active Smelting Furnace.
• If it is exploded inside a Medium Gas Canister, the blast is smaller than if a single Hydrogen canister is placed on its own.
• When Hydrogen is detonated in a canister, the resulting explosion is slightly larger and takes on a bright blue color.

Because of these properties, Hydrogen should be kept away from open furnaces and explosive setups unless it is being used deliberately. It is especially hazardous in compact storage or production areas where a furnace may be switched on automatically. The blue-toned explosion effect also makes it visually distinct from many other resource accidents, which can help identify what was involved after the fact.

Hydrogen is part of the broader atmospheric resource system, so it fits naturally into automation and large-scale production once a base is established. Players typically use it for manufacturing rather than for direct terrain work, and it is most valuable when collected in sufficient quantity for repeated crafting or processing. When transporting it, a containerized approach is safer, since loose handling around furnace setups can destroy equipment.

In practical use, the main thing to remember is that Hydrogen is both a useful input and a dangerous one. Keep it separated from active refining equipment, and do not treat it like an inert storage resource. Its explosive behavior makes it one of the atmospheric resources that requires the most care during base planning and factory layout.
