ATMOSFAR Hydrogen Fuel: Make Fuel and Refill Your Wasp

To make hydrogen fuel in ATMOSFAR, collect hydrogen crystals, process them in a powered hydrogen refinery and transfer the finished liquid hydrogen to your Wasp. Before transferring, read your active fuel objective: it may ask for fuel held in personal storage rather than fuel already inside the aircraft.

Have hydrogen crystals, a hydrogen refinery and an active electrical supply ready. At a portable camp, the refinery must be crafted, connected to the Camp Hub and supplied with its required raw materials. Check the recipe and connection prompts in your current interface before leaving to collect anything missing.

Check your personal electricity before extracting resources. Your tools draw on backpack power, which is separate from the hydrogen used by the aircraft. A fuelled Wasp therefore does not tell you whether your extractor has enough power for the collection trip.

Search hydrogen-crystal deposits on the floating islands of Tycos. Crystals are most common near hydrogen geysers, making the surrounding ground a useful place to inspect. Extract the crystals and bring them back for processing; collecting the raw resource does not put usable fuel into your Wasp.

Choose a collection position with a clear route back to your workshop. Keep the return trip in mind while deciding how far to search. If the aircraft already needs fuel, avoid turning a nearby supply stop into an unnecessarily long expedition.

Your backpack contains a reserve-fuel container used when refuelling a Wasp, while the aircraft has its own operating fuel supply. Raw crystals, finished fuel in personal storage and fuel transferred to the aircraft represent different points in the supply chain. If the Wasp still reads low after refining, check where the finished fuel is before gathering another batch.

In the March–April 2026 Demo, transferring fuel before meeting a personal-tank target could leave the objective unfinished. Producing enough fuel overall did not necessarily satisfy a requirement to hold it in that container. For Early Access, follow the tank and amount named in your current objective rather than copying the Demo's target or task order.

When supplying camp power from a Utility Wasp, distinguish the rear-right electrical connection from the rear-left fuel inlet. Run the engine and connect the Camp Hub to the electrical connection. Check the current interface labels while making the connection so you are addressing camp power rather than refuelling.

The fuel and power guide covers Camp Hub supply, active demand and refinery inputs. Use it when the fuel chain stops at an electrical problem. Work through the device that stopped first so each check has a clear purpose.

If those checks leave you stuck, report the behaviour through the in-game bug reporting tool. Include the objective wording, the affected machine and what happened when you tried the interaction. This gives the report a concrete problem to describe.

The Cloud Cruiser guide describes onboard refineries that convert crystals into liquid hydrogen stored in fuel tanks. It also covers exterior hydrogen siphons that collect hydrogen from the air. Both production systems require electricity, so include the ship's power supply in your checks when moving beyond the portable camp.
