There are several methods for refilling the UAV fuel cylinders.

1. On Board UAV: This method is suitable when the lightweight composite cylinder is integral to the UAV. The cylinder is filled through a filling hose while attached to the UAV.

2. On The Ground: This method is suitable when the lightweight composite cylinder will be removed from the UAV for refill. It can be done either in-situ or back at base.

3. Cylinder Exchange Filling Service: Cylinders can be filled if you take them to the filling location or they can be delivered directly to you and empties collected by a carrier. You can contact IGX Group, Inc. or NanoSUN for more information on this service.

4. Decanting: Decanting is the direct connection from the source cylinder to the destination cylinder using a decanting hose. This method is ideal for integration and proof-of-concept work. However, it is less efficient for larger operations as the UAV cylinder can only be filled to the pressure remaining in the source cylinder. Decanting hoses are available from Intelligent Energy and Fuel Cell Systems Ltd.

5. Booster pumps: This method allows you to fill the UAV cylinders yourself directly from a bulk high-pressure gas cylinder. An in-line compressor ensures you get a full cylinder, regardless of the source pressure. You can contact Haskel Europe Ltd, MAXIMATOR GmbH, Staffordshire Hydraulic Services Ltd, Hydraulics International, Inc., or MPS (Italy) for more information on booster pumps.

6. Cascade filling: Cascading refueling enables filling of significantly more UAV fuel cylinders to higher fill pressures than the decant option. This approach optimizes utilization of hydrogen from a standard source cylinder. Cascade refuellers require no external power source and work well for field and mobile refueling. The onboard PLC controls filling protocols and safety checks.

For more information on hydrogen availability and suppliers, you can refer to the list provided in the manual.
