Vessel powered by 100% renewables arrives in Sweden

The multi-hull "Energy Observer" sails off the coast of the Swedish capital, Stockholm on May 28, 2019. The high-tech catamaran, part of a project aimed at finding new solutions in favour of energy transition, is on a six-year trip around the world ending in 2022 - with 50 countries expected to be visited along the way. The vessel is powered by solar and wind power, as well as self-generated hydrogen. [Photo: AFP]
