Decarbonizing the Seas: Maritime’s Energy Transition in Charts

114

  • Dual-fuel engines are revolutionizing the maritime industry, with container ships leading the charge in adopting this technology.
  • LNG fleets have grown significantly, becoming a cornerstone of maritime decarbonization.
  • The global seaborne coal trade remains a significant challenge, reaching record highs despite decarbonization efforts.

The maritime industry, responsible for transporting 80–90% of global trade by volume, is critical in the global energy transition. Decarbonization efforts have highlighted progress and persistent obstacles, from adopting cleaner fuel technologies to the ongoing reliance on the coal trade, reports SAFETY4SEA.

Dual-Fuel Engines: A Game Changer

Dual-fuel engines, capable of running on conventional marine fuels and alternatives like LNG, are transforming shipping.

Container shipping, in particular, has embraced this technology, with 65% of new orders in 2024 featuring dual-fuel engines—a dramatic leap from 4% in 2018.

LNG Fleet Growth Fuels Hope

LNG fleets have witnessed remarkable growth over the past decade, doubling capacity and cargo miles.

Supported by increased global LNG supply, this trend underscores LNG’s role as a critical transitional fuel in the maritime sector.

Coal Trade: A Persistent Challenge

Despite global decarbonization goals, the seaborne coal trade hit a record 1.388 billion tonnes in 2023, driven largely by demand from developing nations.

Transitioning away from coal remains one of the maritime industry’s toughest challenges.
