Case Studies
Expert analysis of hydrogen maritime technology: fuel costs, vessel design, regulations, and implementation for zero-emission shipping.
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 cost-per-kWh analysis of three marine fuel alternatives derived from green hydrogen, cross-checked against the Fraunhofer RE-Chain import-cost study and GCMD/BCG’s fleet-economics model.
Key Finding: Using this site’s own Feasibility Tool price curve, green hydrogen is cheapest per kWh today (~€0.17) but ammonia and methanol overtake it from 2030 onward (~€0.15-0.16) as hydrogen’s delivered-fuel cost gets revised upward with real import-chain data — though logistics costs (ammonia’s toxicity handling especially) bring ammonia and methanol back to near cost parity once the full picture is included.
Shipowner’s Guide
What Shipowners Should Know About Transitioning to Hydrogen
A practical decision guide for shipowners evaluating hydrogen propulsion, covering fuel storage options, safety considerations, regulatory frameworks, and implementation strategies.
Topics covered:
- Fuel cells vs. ICE engines and efficiency trade-offs

- Subsidy programs and funding opportunities
- Technology readiness levels and proven suppliers
Safety Analysis
EMSA Technical Analysis: Safety Requirements for Hydrogen-Fuelled Ships
The European Maritime Safety Agency’s comprehensive 2025 study evaluates the safety of hydrogen as fuel on ships for achieving decarbonization targets.
Key findings:
- Inadequacy of current safety codes due to hydrogen’s extreme properties
- Mandatory technical barriers and secondary enclosures required
- Safety management system factors account for 49% of hydrogen-related accidents
