In this study we propose the use of ammonia as a liquid hydrogen carrier. Because ammonia does not contain carbon, CO_2 and CH_4 are not generated through ammonia cracking; instead, H_2 and N_2 are generated at a high temperature. Therefore ammonia has the potential to serve as a ...
AFC Energy also plans to start using green ammonia “for the next stage of the project”, although a timeline for when this will take place and the likely impact of using a higher-price feedstock on the final cost of delivered hydrogen is as-yet unclear. Many developers around the world a...
H2SITE’s membrane reactors make sure all the ammonia is transformed, while delivering a high purity hydrogen to the fuel cell in a single process step. During navigation, as part of the H2OCEAN project, H2SITE’s cracker has successfully powered the ship's auxiliary services. This achievement...
AFC Energy PLC (AIM:AFC, OTC:AFGYF)has unveiled a significant development in its ammonia cracker technology with the pioneering method optimised to transform ammonia into hydrogen with an impressive efficiency rate of 99.99%. Hydrogen is typically derived from ammonia — a compound made of hydrogen...

Certain austenitic stainless steels and aluminium alloys crack in the presence of chlorides, mild steel cracks in the present of alkali (boiler cracking) and nitrates, copper alloys crack in ammoniacal solutions (season cracking), and many metals crack when exposed to liquid metals or when coated...
Mitsubishi Heavy Industries, Ltd. (MHI) and NGK INSULATORS, LTD. (NGK) will jointly develop a hydrogen purification system that uses membrane separation to purify from hydrogen-nitrogen mixture gas after ammonia cracking.
Heavy oils are simultaneously subjected to cracking and dewaxing in the absence of added hydrogen using a catalyst comprising Zeolite Beta and an X or Y or other faujasite zeolite. The process is able
In this largest capacity ammonia cracking plant announced to date, clean hydrogen will serve a planned power plant in Daesan, paving the way for large-scale sustainable hydrogen utilization. Ammonia cracking, the process to convert transported ammonia back to hydrogen, is a key enabler to achieving...
