Case Studies

Expert analysis of hydrogen maritime technology covering fuel costs, vessel design, regulations, and implementation for zero-emission shipping.

Every case study is backed by real numbers, technical specifications, and industry data. Written by a naval architect with hands-on experience in maritime hydrogen technology.

Fuel Economics

Comparing the Energy Costs of Hydrogen, Ammonia, and Green Methanol

A comprehensive cost analysis of three key marine fuel alternatives derived from green hydrogen. Breaking down the economics of compressed hydrogen, liquid hydrogen, ammonia, and green methanol.

Key Finding: While hydrogen offers superior energy density, ammonia and methanol provide cost advantages and easier handling. At €4/kg H2, compressed hydrogen delivers the lowest cost per kWh at €0.24, but methanol at €0.29 offers practical storage benefits.
