The fifth annual Ammonia Fuel Network meeting was held September 29th and 30th in the McNamara alumni center on the University of Minnesota's Minneapolis campus. One hundred and forty registered attendees crammed into a sometimes standing room only auditorium to hear 29 presentations ranging from highly technical catalyst development to ammonia safety to updates on various clean production methods.

The sense among the attendees is that we're at a tipping point – the end of the beginning for ammonia fuel, and the beginning of a much more broad interest in the only hydrogen carrier that can be produced renewably.
