Maritime ammonia engines in Japan; ammonia shipbuilding in South Korea
Article

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."

Strategic collaboration announced between Proton Ventures and Duiker Combustion Engineers
Article

This week, two industry members of the Ammonia Energy Association announced that they have launched a "strategic collaboration." Coming from opposite ends of the ammonia energy value chain, one specialized in production and the other in combustion, this new partnership allows the two companies to "complete the chain of using ammonia as an energy solution."

New Video Summarizes SIP Energy Carriers Accomplishments
Article

ANNOUNCEMENT: The Japanese Government’s Cabinet Office and the Japan Science and Technology Agency have released an English-language video that summarizes the accomplishments of the Cross-Ministerial Strategic Innovation Promotion Program’s Energy Carriers initiative.  The release coincides with the end-of-March conclusion of Energy Carriers’ work, and anticipates this month’s formal activation of the Green Ammonia Consortium.

Dutch Company Breaks New Ground in Ammonia Combustion
Article

Earlier this year the Dutch company Duiker Combustion Engineers shared a company paper with Ammonia Energy that targets ammonia energy as an application for the company’s proprietary stoichiometry-controlled oxidation (SCO) technology.  The technology’s original commercial deployment in petroleum refining occurred in 2010, and now the company sees potentially broad applications for it as a sustainable energy expedient in the industrial and electricity sectors.

SMARTCATS Workshop: Ammonia for Fueling Future Energy
Article

ANNOUNCEMENT: SMARTCATS, an Action within Europe’s “intergovernmental framework” for Cooperation in Science and Technology (COST), has this week published the list of keynote speakers for its Ammonia for Fueling Future Energy Workshop, which will be held on April 13 and 14 in Lisbon, Portugal. Speakers will include John Bøgild Hansen, Senior Scientist at Haldor Topsoe and member of the Ammonia Energy Association (AEA) Board of Directors; Bill David, University of Oxford Professor and member of the AEA Advisory Board; and myself in my role as AEA President.

Exploring ammonia's potential as a marine fuel
Presentation

International shipping is responsible for approximately 90% of the world trade. Looking to the relative emissions, in gram CO2 per ton km, maritime transport score significantly better compared to others like rail, road and airfreight. However, since most of the transport is done by ships the absolute contribution of greenhouse gases (GHG) by the maritime industry is clearly visible. Of all the global emissions the maritime industry is responsible for 3% CO2, 13% SOx, and 15% NOx. To reduce SOx and NOx several regulations are either upcoming or already in play. Current regulations require the sulphur emissions to be less…

Presentation

There are severe issues on increasing amount of carbon dioxide (CO2) emission in the world. Many studies are devoted to alternative fuels. One of promising candidates is the utilization of ammonia which is zero emission of CO2, a hydrogen energy carrier, and also can be burned directly as a fuel. For direct combustion of ammonia in industrial furnaces, there were two issues which were weaker radiative heat flux and a huge amount of NOx emission compared with the combustion of methane. We already have reported [1] the solution of the former issue by using the oxygen enriched combustion. The objective…

Auto-Ignition Kinetics of Ammonia at Intermediate Temperatures and High Pressures
Presentation

The anxiety over global greenhouse gas emissions has intensified the demand for the development and use of CO2-neutral energy technologies. Ammonia is now attracting attention as a carbon-free energy carrier, because it has good energy density (22.5 MJ/kg) and can be easily liquefied (about 10 bar at 298 K). In addition, ammonia is produced according to the Haber-Bosch process, which makes it one of the most widely-produced inorganic chemical in the world. It could also be produced with renewable energy sources such as wind and solar energy using P2X technology. As a potential fuel for applications in gas turbines and…

Improved Method of Using Hydrogen and Ammonia Fuels for an Internal Combustion Engine
Presentation

A tractor mounted internal combustion engine is fueled by Hydrogen or a combination of Hydrogen and Ammonia. Developments of an improved method of fuel injection and ignition control. Hydrogen is port injected in the intake manifold, and liquid ammonia is injected in the throttle body. A dual fuel ECU, Engine Control Unit, controls the fuel mixtures and the firing of multiple coils for ignition. The paper will address significant engine performance improvements and the resulting fuel consumption and engine emissions levels.
