Korean Register Sees Ammonia as Preferred Alternative Maritime Fuel

Stephen H. Crolius February 06, 2020

Last week the classification society Korean Register of Shipping (KR) released Forecasting the Alternative Marine Fuel: Ammonia, a “technical document on the characteristics and the current status of ammonia as ship fuel.” One hesitates to take the title too literally, but the report really does forecast that ammonia will be the alternative marine fuel. Over the last year, a number of maritime transport stakeholders – engine producers, government agencies, other classification societies – have identified ammonia as a promising means of industry decarbonization. But in joining the group, KR makes a notably explicit and complete case in ammonia’s favor.

Ammonia-fueled ships: entering the design phase

Trevor Brown December 12, 2019

Three separate projects to design a range of ammonia-fueled vessels were announced last week at a shipping industry conference in China. Lloyd's Register has granted Approval in Principle (AiP) for the design of a 180,000 ton bulk carrier. ABS announced a project to "produce designs for an ammonia-fueled Chittagongmax container carrier of 2700 TEU capacity." And Lloyd's Register also announced a project for "an ammonia-fuelled 23,000 TEU Ultra-Large Container Ship (ULCS) concept design." All three projects are working with the two-stroke ammonia engine developed by MAN Energy Solutions, and all are led by major shipbuilders in China.

Technical & Economic Study for Commercial Ships with HFO, LNG and NH3 As Fuel

Hyuk KwonMincheol RyuSu-Kyung An

Objective/Scope: International Maritime Organization (IMO) announced the initial strategy for GHG (Green-House Gas) emission of ships according to “Paris Climate Agreement”. In order to resolve the GHG emission issue from ships, a demand for GHG solution technologies is increasing such as alternative fuels and energies. Recently, some reports by some companies and research centers have been presented some positive results on NH3 for ship GHG reduction. And MAN Energy Solutions presented some development plans on ammonia engines for ship CO2 emission reduction. DSME (Daewoo Shipbuilding & Marine Engineering) also thinks that ammonia can be one of options as ship fuel…

Ammonia – Could it replace HFO/LSFO?
Presentation

Ammonia – Could it replace HFO/LSFO?

George Karikoglou

The core of this presentation deals with the nature of ammonia, its natural characteristics that make it a future fuel solution candidate, the safety measures that need to be applied in order to carry it on board without endangering lives, environment & property, as well as whether this would be a feasible and cost- or risk-effective solution. For a long time, a lot of discussions have been centered around this subject, now bringing it to the immediate forefront & creating various questions that we will aim to answer to the interested individuals’, ship-managers’, businesses’, ship-owners’ and corporations’ satisfaction. Lloyd’s Register –…

Safe and Effective Application of Ammonia As a Marine Fuel

Niels de Vries

To achieve significant reduction in greenhouse gas emissions in shipping and enable ship owner’s to eventually phase them out entirely renewable fuels, such as ammonia, play a crucial role. However, much is still unknown regarding application of ammonia as a marine fuel. An ammonia carrier is used as basis to perform the study identifying the marine technical feasibility and performance of ammonia. Furthermore, a safety analysis is performed on the system level providing the first design principles for ammonia powered vessels. The results of this theoretical research will be presented including an outlook on new developments on the implementation of…

Safety of Ammonia As Hydrogen and Energy Carriers

Yoshitsugu Kojima

Ammonia (NH3) is liquefied at 1 MPa and 25 °C, and has a highest volumetric hydrogen density of 10.7 kg H2 /100L. It has a high gravimetric hydrogen density of 17.8 wt%. The heat of formation of NH3 is about 1/10 of combustion heat of hydrogen. NH3 has advantages as a hydrogen carrier for fuel cell vehicles and an energy carrier for power plants. In this research, the purpose is to figure out regulations for safety of NH3 in the world, and survey NH3 accident. We also characterize water as a NH3 absorbent. Regulations for flammability and health hazard are…

Safety of Ammonia Energy: First Up, the Maritime Use Case?

Stephen H. Crolius November 07, 2019

ANNUAL REVIEW 2019: Ammonia.  A hazardous chemical, no doubt.  But is it too hazardous to use as an energy vector?  This is a legitimate question that must be addressed as other aspects of the ammonia energy concept advance.  It is also a question whose unique context can be evoked with two other questions: Haven’t the safety issues already been identified and resolved over the last 100 years of widespread agricultural and industrial use?  And even if they have, how will the general public react when proposals for expanded ammonia infrastructure suddenly appear? The earliest tip of this particular iceberg came into view this year when the Dutch naval architecture firm C-Job released Safe and Effective Application of Ammonia as a Marine Fuel.

Bunker Ammonia: Rapid Cross-Sector Progress from Industry, Government, Finance, and Class Societies

Trevor Brown August 09, 2019

The maritime industry has been engaged in a frenzy of research since April 2018, when the International Maritime Organization (IMO) announced its Initial GHG Strategy mandating a 50% reduction in shipping's emissions by 2050. Three recent announcements illustrate the speed and depth of progress across a range of maritime stakeholders. In the government sector, the UK has launched its Clean Maritime Plan, which identifies ammonia as one of its strategic "clean growth opportunities." In finance, a coalition of 11 banks representing a shipping portfolio of around $100 billion has launched the Poseidon Principles to "redefine the role of banks in the maritime shipping sector." And class society ABS launched its Global Sustainability Center in Singapore to analyse, certify, and validate alternative fuels and new technologies; its Director of Global Sustainability will speak at the inaugural conference of the Ammonia Energy Association--Australia, held in Clayton, VIC, on August 22-23. His subject will be "Green ammonia as marine bunker fuel."

Safe and Effective? New Study Evaluates Ammonia as a Marine Fuel

Stephen H. Crolius August 07, 2019

In mid-June the Dutch naval architecture firm C-Job released "Safe and effective application of ammonia as a marine fuel," a thesis written by the firm’s Lead Naval Architect Niels de Vries for the Marine Technology Master of Science program at the Delft University of Technology in the Netherlands. While the thesis delivers an extensive assessment of ammonia's potential effectiveness as a marine fuel, it breaks new ground in its consideration of ammonia's safety in this context.
