Successful Pure-Methanol Engine Test

In October 2025, Rolls-Royce announced that it had successfully tested a high-speed MTU marine engine powered entirely by methanol. The test represented an important milestone in the development of lower-carbon, methanol-powered marine propulsion.

New MTU Yacht Engine Announced in 2025

In September 2025, Rolls-Royce presented a new MTU yacht engine rated at approximately 2,222 hp and discussed further integration of bridge systems, hybrid powertrains, batteries, intelligent energy management, and methanol technology.

Record Tugboat Demand

Rolls-Royce reported in May 2026 that 2025 was its most successful year for MTU tugboat propulsion systems. By May 2026, propulsion systems had already been sold for 17 additional tugboats.

Continued Marine Digitalisation

In June 2026, Rolls-Royce announced an expansion of digital training for the German Navy, reflecting the growing importance of digital support, technical training, and lifecycle services for MTU-powered fleets.

Hybrid Propulsion Development

Rolls-Royce continues to develop modular MTU hybrid marine systems combining diesel engines, electric drives, batteries, automation, and energy management.

Hybrid propulsion is especially relevant for:

• Tugboats
• Ferries
• Yachts
• Superyachts
• Patrol craft
• Workboats
• Passenger vessels
