Using ammonia as a shipping fuel could disturb the nitrogen cycle

Ammonia has been proposed as a shipping fuel, yet potential adverse side-effects are poorly understood. We argue that if nitrogen releases from ammonia are not tightly controlled, the scale of the demands of maritime transport are such that the global nitrogen cycle could be substantially altered.

Ammonia as a shipping fuel may have potential adverse side-effects, and if nitrogen releases from ammonia are not tightly controlled, it could significantly alter the global nitrogen cycle.
