Green Shipping and Decarbonisation of Maritime Transport: Alternative Fuels and Technologies

Green shipping and decarbonisation of maritime transport are crucial to achieving global climate goals, especially the International Maritime Organization (IMO)’s zero-emission target by 2050. Maritime transport handles about 80% of global trade and contributes approximately 2-3% of global CO2 emissions (around 1 billion tons of CO2 annually).

Alternative Fuels

Green Ammonia

  • Potential: Produced from renewable energy, zero-carbon fuel. High energy density and compatible with existing storage/transport infrastructure.
  • Applications: Suitable for large ships (e.g., container ships, bulk carriers).
  • Challenges:
    • Requires advanced control systems for toxicity and NOx emissions.
    • High production costs (2-3 times more than traditional bunker fuel).
    • Bunkering (fuel supply) infrastructure is still ....
