What started as a bold concept has become tangible proof. The engine has been built, tested, and is now preparing for its first real mission: cutting emissions from offshore operations by at least 70 percent. In August 2025, the project partners gathered for a project meeting in Vaasa, and also got to see the engine which shortly will be ready for its factory acceptance test.

“In less than a year, this will be the world’s first offshore vessel running on ammonia, showing that we can drastically cut emissions while keeping safety at the forefront. I’m proud to coordinate this incredible collaboration and excited to see how these results will accelerate the maritime industry’s green transition,” said Emilie Dorgeville, Project Manager at Maritime CleanTech.

New Chapter

The project, backed by EU funding, represents a new chapter for the maritime industry. In 2026, Eidesvik Offshore’s Viking Energy will begin operations for Equinor, powered by ammonia. The demonstration proves that zero-emission fuels are no longer distant dreams, but market-ready solutions.

Maritime CleanTech CEO Ada Jakobsen highlighted the broader significance:
“Decarbonisation is urgent, but also possible. Early movers like the Apollo partners are showing how collaboration and courage can deliver results the whole industry needs. This is the kind of innovation that will set the pace towards 2030 and beyond.”

For Apollo, the message is clear: the transition is not coming — it is here.
