Stricter international environmental regulations are pushing shipowners to explore new fuel options, making technology more demanding and complex. The global shipping fleet has grown since 2008, aiming to cut greenhouse gas emissions by 50% by 2050.

This goal necessitates carbon-free fuels, bringing ammonia into focus. Ammonia (NH3) burns without producing CO2, making it a viable green fuel. International congresses and development partnerships are advancing the topic, and companies like HEROSE are prepared with valves designed for ammonia use.
