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.

MAN ammonia engine update

Trevor Brown January 30, 2020

In November 2019, MAN ES published a technical paper describing the design and performance of its two-stroke green-ammonia engine. The paper also quietly announces the intentions of MAN ES to exploit ammonia energy technologies in a new business case, Power-to-X (PtX, "the carbon-neutral energy storage and sector coupling technology of the future"). In other words, MAN is moving into green ammonia fuel production.

Our Improved Farm Tractor Ammonia and Hydrogen Fueling System

David Toyne

We have a large farm tractor that is fueled by a mixture of ammonia and hydrogen, or hydrogen alone. We will briefly describe the fueling and ignition improvements that have been made to the engine, and quantify the performance increases. These improvements can be applied to other internal combustion engine applications. This tractor runs only on renewable and CO2 free fuels.

High-Efficiency Two-Stroke Internal Combustion Engine

James Ganley

Long-term storage of electricity generated from variable renewable energy resources sources can be achieved by converting the electricity into the chemical energy of a combustible fuel. The conversion process usually involves electrolysis of water to produce hydrogen, which may either be stored directly as a high pressure gas or converted to a more energy-dense fuel such as ammonia. In either case, the fuel can be stored for days, weeks, or even months and then, when its energy is needed, it can be burned in a heat engine. The heat engine can be used to drive an electrical generator, thereby reclaiming…

Maritime ammonia engines in Japan; ammonia shipbuilding in South Korea

Trevor Brown September 27, 2019

This week, Japan Engine Corporation (J-ENG) announced the launch of a new R&D program, in collaboration with the National Maritime Research Institute, that focuses on engine development for "combustion of carbon-free fuel (e.g. hydrogen and ammonia)." Five hundred miles across the Sea of Japan, DSME has completed a techno-economic feasibility study comparing three fuels: HFO (with scrubber), LNG, and ammonia. The results of this study will be presented at the Ammonia Energy Conference, in Orlando, FL, on November 13. DSME is one of the three big shipbuilders in South Korea, and its business case for ammonia is strong enough that now "DSME is planning to expand our technology and business to NH3 engineering and systems for commercial ships."

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."
