Hydrogen fuel energy: the future of maritime transport
- Published 9 December 2024; updated 30 September 2026; estimated reading time 4 minutes. The article presents hydrogen as a potential clean maritime fuel and distinguishes production routes: “green” hydrogen from electrolysis using renewable electricity; “blue” hydrogen mainly from natural gas with CO₂ captured and stored; and “grey” hydrogen from natural gas without carbon capture. It says green hydrogen has no process CO₂ emissions but is expensive, storage permanence for captured blue-hydrogen CO₂ remains uncertain, and grey hydrogen emits around 10 tonnes CO₂ per tonne H₂. These are the article’s simplified descriptions and page-cited figures.
- Hydrogen is versatile and can be used in fuel cells or combustion engines, but production is energy-intensive and low volumetric energy density complicates storage/transport, requiring high-pressure or cryogenic systems and new infrastructure. Upfront transition costs are also a challenge.
- Hydrogen combustion engines burn hydrogen with oxygen and produce water, but the page says they are less efficient than fuel cells and can emit nitrogen oxides. Fuel cells generate electricity through an electrochemical reaction and produce water and heat as by-products; the article describes them as more efficient and zero-emission at use.
- The maritime examples include MF Hydra, identified as the first liquid-hydrogen fuel-cell ferry, and river cargo vessels FPS Waal and Zulu06, which were retrofitted with hydrogen fuel cells. The article says hydrogen can support longer-range shipping than batteries, but acknowledges high initial costs and frames adoption as dependent on future scaling and competitiveness.
