It is not ammonia powered. It is hydrogen powered. The hydrogen is pulled from the ammonia and used in the fuel cell. Doesn't the hydrogen in the ammonia originally come from coal or gas? So, is this more of a test for using ammonia as an intermediary storage for hydrogen fuel? Not the headline but that seems way more of a revolutionary concept. That could make the hydrogen economy competitive with gasoline?
