The National University of Singapore (NUS) has initiated a new project aimed at developing next-generation ammonia-fuelled marine engines to aid the decarbonisation of the global shipping industry. Officially launched on 4 February 2026, the project is led by the NUS Centre for Hydrogen Innovations with support from the Singapore Maritime Institute and various international partners. The research focuses on a novel in-cylinder reforming gas recirculation (IRGR) engine concept designed to improve efficiency and reduce emissions.
