This year marked a turning point for maritime innovation, with propulsion technologies advancing at an unprecedented pace to meet the dual challenges of decarbonisation and efficiency. The industry is moving beyond compliance to proactively explore groundbreaking solutions, from alternative fuels to hybrid systems, that promise to redefine ship propulsion. The Motorship sought insights from some of the sector’s most influential leaders on the technologies poised to make the biggest impact in the year ahead.

Question:  What are the most promising advancements in propulsion technologies that you foresee gaining traction in 2025, and how might they impact fuel efficiency and emissions reduction?

Roger Holm, president of Wärtsilä Marine and excutive vice president of Wärtsilä Coroporation: ”The most significant developments for 2025 will be in multi-fuel capable engines. Ammonia engines – which are dual-fuel as well - are moving from development to commercial deployment, while dual-fuel engines operating on LNG have achieved substantial reductions in methane emissions, down to as low as 1.1% of fuel use.
