IT系统专家

H55 is the electric aviation pioneer born from Solar Impulse, the first aircraft to fly around the world on solar energy alone. Our mission is to make air transport clean, safe, and affordable by building the certification-grade energy storage systems the industry needs to scale.

What we build is meant to fly. Not just prototypes, but certified systems that operate in real-world conditions. That requires discipline across engineering, safety, and the way we run the business.

Based in Sion, Switzerland, with a growing international footprint, H55 is entering a pivotal new phase as we expand our operations and build the foundation for the next stage of electric aviation.
