The Comprehensive Resource for Hydrogen-Powered Maritime Transport

Tracking every hydrogen vessel, funding program, and technology development. Built by a naval architect in Rotterdam. Contact →

Hydrogen is the endgame for zero-emission shipping. Methanol and ammonia are stepping stones — both are made from hydrogen, both add cost and complexity in conversion, and neither is truly clean at the point of use. Hydrogen cuts straight to the result: zero emissions, proven technology, and a growing fleet of vessels already on the water. Backed by €2.5B+ in European funding, the transition is underway.
