Yanmar Hydrogen Fuel Cell Gains DNV Type Approval for Global Maritime Use

Yanmar's maritime hydrogen fuel cell system has received DNV type approval, paving the way for global deployment beyond its Japanese domestic applications. Backed by more than a decade of development and first commercialised in Japan in 2023, the GH-FC series now complies with DNV's rules, making it easier for shipbuilders and operators to adopt the technology. Announced at SMM 2026 in Hamburg, the approval marks a major milestone in the company's plans to offer hydrogen-powered solutions to the wider marine market.

 

Details of the Approval

 

Yanmar has achieved a significant certification. Its maritime hydrogen fuel cell gained DNV type approval. This paves the way for global deployment. The technology was previously used in Japan. It can now reach the wider market.

The approval carries practical significance. It confirms compliance with DNV's rules. This covers the GH-FC series. It makes adoption easier for the industry. Shipbuilders, integrators and operators all benefit.

 

The Development Background

 

The technology reflects long development. Yanmar has developed fuel cells since 2015. This spans more than a decade. The technology was first commercialised in 2023. This occurred in Japan initially.

The company brings relevant heritage. It has a long engine history. This covers internal combustion engines. This experience informs its fuel cell work. It provides a foundation for the technology.

 

The Existing Applications

 

The technology has proven applications. One early demonstration was a fishing vessel. This used a hydrogen fuel cell for power. Electricity is stored in a battery. This powers the ship's systems.

Further applications have followed. The technology went into Tokyo response vessels. A harbour cruise vessel also uses it. That vessel combines fuel cells with batteries. It can operate on hydrogen and biodiesel.

Upcoming Deployments

 

The technology has future applications planned. A new dinner cruise vessel is coming. It will launch in May 2027. The 48-metre vessel combines several systems. These include batteries and diesel engines.

The vessel targets ambitious emissions goals. It will use a Yanmar hydrogen fuel cell. This helps achieve net-zero emissions. It reflects the technology's potential. This demonstrates growing adoption of the systems.

 

The Hydrogen Challenge

 

Hydrogen presents distinct challenges as fuel. Liquid hydrogen liquefies at very low temperatures. This is around minus 253 degrees. Each ship needs specialised storage. Cryogenic onboard storage is required.

However, the technology offers clear benefits. Green hydrogen uses renewable energy. It is expensive to produce. Yet with fuel cells, it produces only water vapour. This eliminates harmful emissions.

 

Significance of the Approval

 

The approval marks a key milestone. Company leadership described it as major. It supports plans for the marine market. The company aims to support the transition. This targets zero-emission operations worldwide.

The approval reflects growing technology maturity. DNV cited increasing confidence in the market. It demonstrates readiness for commercial use. The technology suits varied vessel applications. This positions it for broader adoption in Europe and beyond.
