Japanese initiatives to establish Fuel Ammonia Supply Chain
Presentation

Following brief introduction of CFAA and Marubeni, I would like to present how Japanese government plans to support to realize clean ammonia supply chain for Japan and then draft definition of Clean Ammonia announced by CFAA last year. Some of our thoughts on the Harmonization are presented in the last part of my session using slides titled “International Certification Scheme”.

The IMO charts a course to net-zero
Article

The IMO member states have agreed to a new roadmap for the decarbonisation of the global shipping sector, including emissions reduction targets to be met in 2030 and 2040. It was also established that a well-to-wake approach will be the basis for the lifecycle analysis of maritime fuels going forward, with the uptake of near or zero-carbon alternative technologies & fuels to account for 5 - 10% of the global shipping sector by 2030.

New marine engine collaboration, safety systems and key AiPs awarded
Article

A new MoU between WinGD and Mitsubishi Shipbuilding will see the deployment of WinGD’s X-DF-A ammonia-fueled engines to a range of vessels. In Norway, Wärtsilä has unveiled a safety system designed for continuous onboard monitoring of ammonia leaks, featuring a staged combustion process to deal with accidental releases. And classification society DNV has awarded AiP to two significant ammonia-fueled vessel designs: the MS NoGAPs, and Viridis Bulk Carriers’ short sea bulk carrier.

Maritime updates: modeling engine room fuel leaks, testing a new fuel supply system
Article

ABS has used computational fluid dynamics to model ammonia dispersion patterns in a ship’s engine room, with the aim of producing a fast, real-time response system for ammonia leaks. In Japan, a fuel supply system for large-scale, low-speed, two-stroke marine engines is undergoing final verification testing. Mitsubishi Shipbuilding aims to become a key technology provider of such systems, and in the ammonia maritime fuel space.
