RINA has awarded Type Approval to Baker Hughes for its NovaLT 16 gas turbine, which can run on up to 100% hydrogen for marine propulsion. The certification, announced at Posidonia 2026, removes a major barrier to hydrogen combustion at sea by providing class society endorsement. The turbine operates in the 12 to 17 MW range and can switch between natural gas, blended fuels, and pure hydrogen without hardware modifications. This fuel flexibility allows shipowners to adopt the technology now on natural gas and transition to hydrogen as fuel supply develops. The NovaLT 16 has a 35,000-hour maintenance interval and a 24-hour engine swap capability, making it practical for commercial shipping where uptime matters. The certification signals that high-power-density hydrogen propulsion is moving from theory to deployable hardware.

Type approval for a hydrogen gas turbine is a concrete step. The fuel flexibility without hardware changes is the key detail. If the hydrogen supply chain matures, this could actually get deployed.

35,000 hour maintenance interval and 24 hour swap are practical specs. But where is the hydrogen coming from for marine applications? Electrolytic hydrogen at scale is still expensive and port infrastructure is barely started.

The certification matters because it removes a regulatory blocker. But the article glosses over the fuel supply question. Without mandates or subsidies for green hydrogen bunkering, this stays a niche option for early adopters.

Running on natural gas now with a hydrogen upgrade path is a realistic commercial strategy. The question is whether the carbon intensity improvement from blended fuels is enough to meet IMO targets.

The 12 to 22 MW range covers a lot of vessel types. If the total cost of ownership works out versus dual fuel diesel engines, this could find a real market. Need to see the capital cost delta.
