Bertrand Piccard took the opportunity to give his "personal friend", Grand Duke Henri, a ride during his stay in Luxembourg.
Piccard, the man behind the Solar Impulse project, is currently trying to establish a new world record for distance covered on board a hydrogen vehicle.
His attempt brought him to Luxembourg on Monday, where he met with Grand Duke Henri, whom he describes as a "head of state with a passion for clean technologies". The meeting was documented on social media by the Swiss national and the Grand Ducal Court.
Tthis week, Piccard will attempt to cover a distance of 700 kilometres while driving a hydrogen car, the Hyundai Nexo, an electric SUV fuelled with hydrogen via a fuel cell. Marketed since 2018 in France, the car symbolises the path taken by the brand, who announced their investment in hydrogen technology in 2013.
