Mitsubishi Shipbuilding  a part of Mitsubishi Heavy Industries Group, has received an order from Hitachi Zosen Marine Engine for its MAmmoSS® ammonia fuel handling system.

HZME is a dual licensee of Everllence SE and WinGD, major licensors of marine engines. MAmmoSS® will be designed and optimized to be compatible with the ammonia marine engines of these two licensors, and after delivery to HZME’s facility, will be used for shop tests of both engines.

The International Maritime Organization (IMO)’s Marine Environment Protection Committee (MEPC) has been engaged in ongoing discussions on reducing greenhouse gas (GHG) emissions from international shipping. The MEPC 80 session adopted the 2023 IMO Strategy on Reduction of GHG Emissions from Ships, which aims to reach net-zero GHG emissions from international shipping by 2050, while MEPC 83 approved mid-term measures to reduce GHG emissions.

Decarbonization in global shipping is a critical issue, and ammonia, which does not emit CO₂ when burned, is attracting attention as a next-generation marine fuel that will significantly contribute to reducing GHG emissions in the shipping industry. However, as ammonia is a toxic fluid, safe handling technology onboard ships is essential and is expected to drive demand for MAmmoSS®.

Going forward, Mitsubishi Shipbuilding will continue to provide safe and reliable products for ammonia-fueled vessels to support the expected market expansion, while also enhancing functionality and deliver greater value to meet the diverse needs of customers.
