Shipping is experiencing increasing pressure to decarbonize its operations and to reduce emissions to air. In April 2018, the IMO adopted an ambitious GHG reduction strategy, aiming to reduce with at least 50% total GHG emissions from shipping by 2050. As it is expected, such an unprecedented change, poses challenges for a range of stakeholders, from ship owners, to ship builders, designers, and fuel suppliers financiers and policy makers.

Hyundai Mipo Dockyard recently received an Approval in Principle (AiP) from Lloyd’s Register concerning its ammonia-powered design of a 50,000 dwt MR tanker.

Wärtsilä, in cooperation with Knutsen OAS Shipping AS and Repsol, and the Sustainable Energy Catapult Centre, will start the world’s first long term, full-scale, testing of ammonia as a fuel in a marine four-stroke combustion engine.

Following a greener path, the shipping industry is constantly searching for alternative fuels that will be in line with the environmental regulations, with LNG currently seeing a high demand.

Shipowners believe that ammonia and hydrogen are the most attractive fuel options for the long term, according to an ABS survey.

Decarbonization has been a major issue of discussion; Now, a new paper highlights that two potential low-emission fuels for long distance international shipping could be hydrogen (H2) and ammonia (NH3).

Internal combustion engines (ICEs) represent the dominant technology in marine propulsion today. If ICEs are to play a role in the decarbonization of shipping, suppliers, regulators, shipowners and engine manufacturers will have to agree on viable alternatives to carbon-based fuel, argues Dr Christos Chryssakis, Business Development Manager at DNV GL.

Imabari Shipbuilding along with MAN Energy Solutions, Mitsui E&S Machinery, ClassNK, ITOCHU ENEX and ITOCHU Corporation shake their hands and signed an agreement in order to jointly develop vessels equipped with ammonia-fueled engine and achieve net zero emissions. 

A group of companies has come together to develop a better understanding of the practical realities involved in using ammonia as a fuel for ships.

During the 2020 SAFETY4SEA Limassol Forum, Dr. John Kokarakis, Vice President Technology & Business Development, Bureau Veritas, discussed ammonia as a potential solution for carbon-free shipping. During his presentation, Dr. Kokarakis presented the advantages of ammonia on the one hand, and the challenges on the other, adding that difficulties around ammonia can be controlled by technical and regulatory options.
