Arriving in the Vietnamese southern hub on Wednesday, the crew plans to present the ship's autonomous zero-emission system to several hundred visitors, decision-makers, students and school children in collaboration with the French Consulate in the city.

The main missions of the Energy Observer expedition consist of accelerating transition through innovation by demonstrating how well the onboard technologies and energy mix work in extreme environments and how they can be duplicated on a wider scale both on land and at sea.
