DNV Sees Limited Role for Pure Hydrogen in Shipping
Pure hydrogen as a marine fuel is likely to play only a limited role in international shipping because of storage and energy-density constraints, according to a new report from classification society DNV.
Both compressed and liquefied hydrogen face challenges linked to low volumetric energy density, reducing their practicality for long-distance marine transport, according to a report published on Tuesday.
“As a result, hydrogen demand from the maritime sector arises almost exclusively through fuels where hydrogen is embedded in higher-density molecules that are easier to store, transport, and bunker at scale,” DNV said in the report.
Instead, DNV expects shipping demand to centre on hydrogen-derived fuels such as ammonia and e-methanol as the industry pursues decarbonisation targets in hard-to-electrify sectors.
The report forecasts clean hydrogen volumes growing 100-fold by 2060, supported by cumulative sector investment of about $3.2 trillion.
DNV said hydrogen could help cut more than 2 billion mt/year of emissions from sectors including shipping, aviation and heavy industry by mid-century.
The organisation sees Australia as a pivotal supplier of both hydrogen and ammonia.
“As a result, the most significant trade corridors are expected to run from Australia to Japan, South Korea, and Singapore, collectively accounting for roughly two‑thirds of all regional hydrogen-related trade,” the report stated.
It expects South Korea and Japan to import hydrogen and ammonia for power generation, while Singapore's imports would be largely for ammonia bunkering requirements.
