Case Studies
In-depth analysis and technical deep-dives into hydrogen maritime technology, economics, and implementation strategies.
Comparing the Energy Costs of Hydrogen, Ammonia, and Green Methanol
A comprehensive cost analysis of three key marine fuel alternatives derived from green hydrogen. This study breaks down the economics of compressed hydrogen, liquid hydrogen, ammonia, and green methanol, examining how hydrogen pricing impacts delivered energy costs.
- Energy density comparison: H₂ (33.3 kWh/kg) vs NH₃ (5.17 kWh/kg) vs Methanol (5.53 kWh/kg)
- Cost per kWh delivered at different H₂ price points (€4, €6, €8/kg)
- Efficiency considerations: fuel cells (50%) vs combustion engines (40%)
- Impact of liquefaction costs on hydrogen economics (+25% for LH₂)
- CO₂ pricing effects on green methanol production costs
What Shipowners Should Know About Transitioning to Hydrogen
A comprehensive technical guide for shipowners navigating the transition to hydrogen propulsion. Covers everything from fuel storage options and safety considerations to regulatory frameworks and implementation strategies.
- Hydrogen Forms: Compressed (350-700 bar), liquefied (-253°C), and carriers (ammonia/methanol)
- Storage Requirements: 7.18 m³ of CH₂ or 4.73 m³ of LH₂ replaces 1 ton HFO
- Technology Options: Fuel cells vs. ICE engines, efficiency trade-offs
- Regulatory Landscape: IMO targets, EU ETS, FuelEU Maritime, subsidy programs
- Cost Analysis: Green H₂ at $4-6/kg, equipment costs (~€1,500/kW for fuel cells)
- Implementation Strategy: Feasibility studies, retrofit vs. newbuild decisions
