Zephyr is built to realise not only the highest ambitions for global connectivity but also to support the United Nations Sustainable Development Goals (SDGs) and the highest hopes for safeguarding our environment.

Flying in the stratosphere, Zephyr relies on solar energy, not fossil fuel, and with secondary batteries charged in daylight to power overnight flight, Zephyr’s flight time is 100% emissionless.


Locating connectivity and Earth observation services in the stratosphere is uniquely advantageous and ensures stratospheric operations even in the most demanding environments, at no cost to the environment itself.

And when Zephyr lands, it can be reused, leaving no debris behind.
