Solvay and Solar Impulse: Game-changing clean technologies make the impossible possible!

In July 2016, Solar Impulse, the first ever zero-emission aircraft powered exclusively by solar energy, landed in Abu Dhabi and completed its world tour. Since the take-off in March 2015, pilots Bertrand Piccard and André Borschberg traveled more than 40,000 km, flew across two oceans and shattered eight world records. We congratulate them on this extraordinary achievement, which marks the successful close of a project that has been 13 years in the making.

We are extremely proud and honored to have been the first technological partner in this visionary and far-flung project over the past decade. From the beginning, the concept of designing, building and flying a zero-emission aircraft around the world totally aligned with our own unwavering commitment to develop transformative clean technologies that ease the world’s dependency on carbon-emitting fossil fuels.


A fruitful partnership


We also saw it as yet another chance to demonstrate chemistry’s ability to "make the impossible possible" and we had to be a part of it. Our researchers, chemists and engineers left their marks on the Si1 and Si2 planes which carry more than 6,000 Solvay parts. Solvay’s 15 products on Si2 enhance its performance while keeping weight to a minimum. We developed clean-sheet solutions that dramatically improve the energy chain, enhance the structure and reduce the weight of the solar-powered aircraft – all crucial elements that made this historic flight a success and that are used today in the transportation industry for a cleaner mobility.
