RAL proposes new efficient and low-cost process to crack ammonia for hydrogen using sodium amide; transportation applications

Green Car Congress

RAL researchers are proposing a new process for the decomposition of ammonia to release hydrogen that involves the stoichiometric decomposition and formation of sodium amide from Na metal. The new process decomposes ammonia using the concurrent stoichiometric decomposition and regeneration of sodium amide (NaNH 2 ) via sodium metal (Na); this is a significant departure in reaction mechanism compared with traditional surface catalysts.
