The shipping industry faces a difficult transition from heavy fuel oils to zero-carbon alternatives. Liquefied Natural Gas (LNG) is positioned as a bridge fuel that reduces immediate emissions while the infrastructure for hydrogen and ammonia scales up. This shift requires significant investment in dual-fuel engines and bunkering infrastructure. The goal is to lower the carbon intensity of global trade without compromising the reliability of maritime logistics.

The bridge fuel argument only works if there is a hard deadline to move past LNG. Without strict regulatory triggers, the industry might just lock in gas infrastructure for another thirty years.
Agreed. I am more worried about the methane slip from these engines. If the leakage is high, the actual carbon benefit over traditional bunker fuel is much smaller than the brochures claim.
Interesting look at the shipping gap. It is basically the same struggle we see in industrial heat. Everyone wants the end goal, but the mid-step is where the actual money and risk are right now.
The cost of retrofitting existing hulls for LNG or future fuels is the real bottleneck. Most owners will just run their current ships into the ground unless subsidies make the switch cheap.
