Make Hydrogen Happen
From the National Science Foundation: Ammonia fuel offers great benefits but demands careful action<> Role in a carbon-free fuel system as a way to transport and store clean hydrogen
Ammonia, a main component of many fertilizers, could play a key role in a carbon-free fuel system as a convenient way to transport and store clean hydrogen. The chemical, made of hydrogen and nitrogen, can also be burned as a zero-carbon fuel.
However, new research led by Princeton University<> scientists illustrates that even though it may not be a source of carbon pollution, ammonia’s widespread use in the energy sector could pose a grave risk to the nitrogen cycle and climate without proper engineering precautions.
Publishing their findings in PNAS<>, the U.S. National Science Foundation<>-supported team found that a mismanaged ammonia economy could ramp up emissions of nitrous oxide, a long-lived greenhouse gas around 300 times more potent than carbon dioxide and a major contributor to the thinning of the stratospheric ozone layer.
It could lead to substantial emissions of nitrogen oxides, a class of pollutants that contribute to the formation of smog and acid rain. And it could directly leak fugitive ammonia emissions into the environment, forming air pollutants, impacting water quality and stressing ecosystems by disturbing the global nitrogen cycle. {Read more at the NSF website<>}
