Hydrogen, the fuel of the future?

A remarkable vessel sailed into the port of Amsterdam recently. She is called Energy Observer and the name says it all. The French vessel sails emission free and the stop in Amsterdam is part of a 6 years voyage in which the vessel visits 50 countries. The goal of the journey is to promote hydrogen as a (marine) fuel. The Port of Amsterdam and the Port of Rotterdam are already making plans to make hydrogen a part of their infrastructure.
