A new initiative at the National University of Singapore aims to accelerate the decarbonization of shipping by developing ammonia-fueled marine engines. The innovative in-cylinder reforming gas recirculation (IRGR) design enhances combustion efficiency and reduces emissions. Collaborating with various institutions, the project seeks to establish Singapore as a leader in sustainable maritime technology.
At the GasTech 2025 Exhibition in Milan, Everllence, along with HD Hyundai Heavy Industries and HD Hyundai Mipo Dockyard, announced a strategic partnership to develop a next-generation medium-sized gas carrier powered by Everllence’s ammonia-fueled engine. This collaboration aims to advance zero-carbon propulsion in the maritime industry.
Amon Maritime from Norway has launched Amon Bulk, focusing on ammonia-fueled bulk carriers, backed by a NOK253 million grant from Enova. The initiative targets capesize and kamsarmax vessels, aiming for operational status by 2029. CEO André Risholm views this as a vital step toward decarbonizing deep-sea shipping.
Japan Engine Corporation has made significant strides in developing the first ammonia-fueled commercial shipping engine. Alongside major manufacturers like MAN and WindGD, they are close to certifying and shipping their engines. J-ENG successfully co-fired ammonia in a large engine, a major milestone. The company aims to lead in next-gen fuel engines.
A significant milestone in sustainable maritime energy has been achieved with the Approval-in-Principle certificate for an ammonia-fueled bunkering vessel. Designed by NYK and partners with expertise from Seatrium’s subsidiary, the vessel will undergo evaluation by the MPA to establish ammonia as a marine fuel, showcasing leadership in alternative fuels.
