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?

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…

Maritime fuel mix could be 25% ammonia by 2050

Trevor Brown September 20, 2019

DNV GL published its annual Energy Transition Outlook last week, which includes a dedicated analysis of the shipping industry in its Maritime Forecast to 2050. According to DNV GL, the IMO's 2050 emission reduction targets can be met through innovative ship design, using ammonia as an alternative fuel. Widespread commercial adoption of ammonia fuel would begin in 2037; ammonia would the dominant fuel choice for new builds by 2042; and ammonia would represent 25% of the maritime fuel mix by 2050. This represents new demand for roughly 120 million tons per year of green ammonia by 2050. This outcome greatly depends on how maritime regulations are developed in the coming years, but it would see ammonia-fueled ships represent almost 100% of new vessels (by fuel consumption) from 2044 onwards.

Ammonia = Hydrogen 2.0 Conference: panel discussion recap

John Mott September 12, 2019

The Ammonia Energy Association Australia’s Ammonia = Hydrogen 2.0 Conference took place on 22-23 August 2019 in Melbourne, Australia. It attracted 115 attendees from industry, government, and research institutions. This is the first of two articles about the event; this article recaps the interactive panel sessions and the second article will highlight selected presentations. The panel discussions were placed at the end of the program so that important themes from the presentations could be highlighted and integrated. These themes included: 1) Building an energy export industry using green ammonia; 2) Green ammonia as a maritime bunker fuel; and 3) Green ammonia as grid scale energy storage – a battery to the nation.

Alternative low carbon energy for maritime application

Koh Eng Kiong

Singapore is the largest trans-shipment seaports in the world that has connectivity to 600 ports in over 120 countries. The country has a thriving maritime cluster that comprises over 5,000 maritime-related establishments contributing about 7% of the nation’s gross domestic product. With the growth in world trade and expanding future port activities, the Greenhouse Gases (GHG) emission from the local ports is expected to increase in tandem to support the wide range of essential port services. This is a challenge for Singapore and the maritime industry as global climate change agreements call for the reduction in GHG emission. This presentation…
