The technologies will control and monitor the vessel’s hybrid energy system, which includes ammonia-to-hydrogen conversion, dual fuel cells, battery storage and renewable inputs.

This is expected to ensure real-time optimisation, system safety, and operational autonomy at sea.

The French shipbuilder, Energy Observer, will deploy EO3 to test low-carbon energy technologies in real sea conditions.

“For nearly a decade, Rockwell Automation has supported Energy Observer’s mission to pioneer sustainable energy solutions at sea,” Rockwell’s Emmanuel Guilhamon said.

“EO3 represents the next chapter in our collaboration, combining advanced automation, data management, and human creativity to drive real progress in maritime decarbonisation.”

Energy Observer’s first hydrogen-powered vessel completed its 68,000-mile global voyage in France last year.

The Odyssey set off in 2017 and sailed through the Mediterranean, Northern Europe, Asia, Africa and North America.

Building on the initial developments, Energy Observer 2 will be a liquid hydrogen-fuelled cargo vessel designed for zero-emission navigation, while EO3 will serve as the next floating laboratory.
