The Korean New Deal and ammonia energy
Article

South Korea has featured in many Ammonia Energy news updates, but often in a scatter gun fashion that lacked the momentum of ammonia energy announcements coming from the other side of the Korea Strait. Now, South Korea is ready to step out from Japan’s shadow as a clean energy innovator and deployer in its own right. We’re seeing the beginnings of a well-articulated strategy to achieve society-wide decarbonisation in South Korea, with a starring role for clean hydrogen and clean ammonia.

The Ammonia Wrap: new funding and investment for ammonia energy rolls in, next steps for Uruguay, and Sumitomo to develop a hydrogen
Article

Welcome to the Ammonia Wrap: a summary of all the latest announcements, news items and publications about ammonia energy. This week: new funding and investment for ammonia energy (Starfire Energy, GenCell, Syzygy Plasmonics and Hazer Group), marine engines from the "Ammoniamot" consortium, Uruguay's national hydrogen strategy takes another step, Onahama Port to investigate hydrogen & ammonia imports and Sumitomo to develop Gladstone's hydrogen "ecosystem".

Cracking Ammonia: panel wrap-up from the Ammonia Energy Conference
Article

When should we be cracking ammonia? How much should we be cracking? How could better cracking technologies open up new end uses? What are the critical challenges still to be overcome for cracking ammonia? On November 17, 2020, the Ammonia Energy Association (AEA) hosted a panel discussion moderated by Bill David from Science and Technology Facilities Council (STFC), as well as panel members Josh Makepeace from the University of Birmingham, Joe Beach from Starfire Energy, Gennadi Finkelshtain from GenCell Energy, Camel Makhloufi from ENGIE, and Michael Dolan from Fortescue as part of the recent Ammonia Energy Conference. All panelists agreed that cracking technology as it stands has a number of key areas to be optimised, particularly catalyst improvements and energy efficiency. But, successful demonstrations of modular, targeted cracking solutions are accelerating the conversation forward.

Ammonia cracking: when, how, and how much?
Presentation

Cracking ammonia to produce hydrogen underpins many of the fuel-based uses of ammonia, and as such is a lynchpin technology in the case for ammonia energy. While in many ways ammonia cracking is a mature technology, systems which are designed specifically for these applications are less common. In this presentation, a general overview of the potential roles of ammonia cracking in facilitating the use of ammonia for energy applications will be outlined, including a survey of established and emerging cracking and purification technologies. A forthcoming project to produce an AEA Ammonia Cracking Technical Paper will be introduced.

Starfire Energy's ammonia cracking and cracked gas purification technology
Presentation

Ammonia cracking is important for both combustion and fuel cell applications. Starfire Energy has verified that a blend of 70% ammonia + 30% cracked ammonia can burn well in a conventional natural gas burner with very low ammonia slip and acceptable NOx using a stoichiometric fuel-air mixture. A 10 MW turbine or internal combustion engine using such a blend will need about 1.44 tonnes of cracked ammonia per hour. Starfire Energy’s monolith-supported cracking catalyst may be ideally suited for this application. Fully cracked ammonia retains several thousand parts per million of ammonia due to thermodynamic limitations. Residual ammonia can damage…

Zero emission aircraft: ammonia for aviation
Article

This week, Reaction Engines announced a “ground-breaking study” on ammonia as a fuel for zero-emission aircraft. This will soon be followed by a demonstration project, “integrating the technology into a ground-based test engine.” The study combines Reaction Engines’ heat exchanger technology with the ammonia cracking technology being developed by the UK’s Science and Technology Facilities Council (STFC). By partially cracking green ammonia to hydrogen, the resulting ammonia fuel mix “mimics jet fuel,” making it possible to adapt existing engines and aircraft to use zero-emission fuels. “This means a fast transition to a sustainable aviation future is possible at low cost.”
