It only needs to be as safe as fossil fuels, or even slightly less safe, if the benefits are higher.

This always bothers me. People freak out about LiIon battery failures, or hydrogen, or ammonia, or nuclear power. But here we are with an entire economy riding on an explosive, firey, dirty fuel that is already causing global climate problems.

Safety concerns should be kept on-par with what we have today. Let’s not throw out a good solution because it can be dangerous in some cases. Any high-energy-dense thing we switch to after fossil fuels is going to release that energy if handled improperly. That concern should be quite low on the list.

Fueling up with ammonia is roughly as dangerous as fueling up with concentrated pesticide, on the health risk scale. It’s much more toxic than gasoline.

And also flammable/explosive.
