Wärtsilä recently broadened the scope of its NextDF technology with the release of its 25DF dual-fuel engine. We spoke to Juha Kytölä, director of R&D and engineering at Wärtsilä, about its new technology and the reasoning behind its development.

Kytölä won the Chief Technology Officer (CTO) of the Year award in 2023, a collaboration between the Technology Industries of Finland and Spinverse to honour leaders who exemplify technological excellence and strategic vision. Kytölä’s recognition highlights not only his individual expertise but also Wärtsilä’s commitment to innovation in advancing clean energy solutions.

In this Q&A, The Motorship delves into Kytölä’s insights on Wärtsilä’s NextDF technology and the development of its latest dual-fuel engine, as well as the broader trends shaping the future of maritime sustainability.
