Solar Impulse

Reaching new heights with Solar Impulse


Solar Impulse is the world’s first solar-powered airplane to run day and night without any fuel or emissions.

Producing non-polluting alternative energies and new materials for the Solar Impulse has allowed Solvay to draw from the very heart of our business. We have been a project partner since 2004, contributing to pioneering technologies and innovations that have resulted in 13 products being used in 25 applications and 6,000 parts. These products improved the energy chain, enhanced the structure, and reduced the weight of the aircraft – crucial elements that helped make this ambitious project a success.
