Shipping classification society Lloyd’s Register has granted Approval in Principle (AIP) to the ammonia fuel supply system (AFSS) developed by Chinese marine technology firm SunRui Marine Environment Engineering.

SunRui claims the ammonia fuel supply system is compatible with MAN Energy Solutions and Winterthur Gas & Diesel's (WinGD) two-stroke ammonia engine. MAN is expected to launch its first ammonia-powered engine by 2024.

Earlier this year, Japanese container shipping firm Ocean Network Express (ONE) placed an order of 10 ammonia- and methanol-ready containerships.

SunRui has previously developed fuel supply systems for LNG and methanol-powered vessels.
