Japan launches $95m subsidy for zero-emission ships

Japan has opened a five-year, $95m subsidy programme to accelerate orders for ships powered by hydrogen, ammonia, methanol, and batteries. The scheme, launched jointly by the transport and environment ministries, aims to promote the adoption of cleaner marine technologies. Eligible spending includes engines, fuel tanks, fuel supply systems, propulsion batteries, and shore power equipment.

Eligible Equipment and Support Levels

The subsidy programme will cover up to half the cost of eligible equipment for hydrogen, ammonia, and fully electric ships. Methanol-fuelled and hybrid vessels can receive support covering up to one-third of equipment costs. The scheme applies to new equipment installed on newbuildings, rather than the full cost of the ships. For international trading vessels, support will be limited to hydrogen- and ammonia-fuelled ships, while domestic projects can include methanol, battery-electric, and hybrid tonnage. The programme has an initial-year budget of ¥1.2bn and will run until January 2031. Applications for the first round are open until December 3.

Government Support for Alternative Marine Propulsion

Japan has been stepping up state backing for alternative marine propulsion. Government-supported projects include land-based testing of marine hydrogen engines and the development of a 40,000 cu m liquefied hydrogen carrier scheduled to enter demonstration service by 2030. Additionally, the government is offering support for the use of lower-emission steel in newbuildings, aiming to further reduce the environmental footprint of ships.

Impact on Ship Operators

The introduction of this subsidy programme is expected to significantly boost interest in zero-emission ship technologies among ship operators. With up to 50% of eligible equipment costs being covered, shipyards and engine manufacturers are likely to see a surge in orders for newbuildings and conversions. However, the programme's focus on hydrogen and ammonia may limit the immediate benefits to those specific technologies, potentially slowing the adoption of other promising alternatives such as methanol or battery-electric power.

While the programme is designed to support the transition to cleaner marine technologies, operators should also consider the broader implications for ship design and operation. The use of zero-emission fuels may require significant changes in ship infrastructure and operational procedures, which could impact costs and schedules.
