Photovoltaic-hydrogen systems are analyzed regarding their usability as energy supply for high altitude platforms in long enduring missions. Main attention is directed to characteristics of current or near term available technology. Specific power weight of photovoltaics and other key components and their dependence on operation mode and power range are assessed. A pre-design of o PV-hydrogen energy supply system is carried out for a stratospheric airship. The calculuated coverage ratio of photovoltaics and load share of energy system mark the frame of usability. Depending on the airship size, shape and other external boundary conditions the total electrical energy demand for full year operation can be covered by a PV-hydrogen energy system of current or near term technology. However, further investigations are required regarding improvement of PV and minimization of thermal effects on lifting gas through photovoltaic generator.
