Founded in 2021, Héole is developing a technology of electric generators in fabrics and membranes based on organic photovoltaic cells: OPVs.

Thanks to this new technology, Héole designs real sails and solar envelopes to meet the energy needs of boats and airships.


Offer a virtuous solution for the unlimited autonomy of sea and airships, thanks to the energy of wind and light.

This formidable technology will supply energy to sailboats, airships as well as buildings, and flexible constructions that are ephemeral or isolated, such as field hospitals or temporary hangars.

With Héole, free ourselves from fossil fuels!


Thanks to a very innovative process, the team has developed a technique for integrating organic solar cells into flexible supports.

Their sail collects the energy of the Wind, but also of the Light to produce the energy onboard!

Be autonomous, carbon-free, clean, silent ………
Say yes to eco-navigation!

Why Héole?

= Heol + Eole

n Breton “Heol” means “sun”…
In Greek mythology, “Aeolus” is the master and steward of the winds.

The sun and the wind being the two components of the autonomy provided by the sails, they have merged these two words and created:

the Builder of energy autonomy.

Héole became an IEEE Entrepreneurship Stars Recipient at CES 2022.
