Cheap ammonia

Unlike at, oh, Saturnine moons like Rhea; on Earth, ammonia has to be manufactured.

Apparently we've been doing that by crashing hydrogen into nitrogen (or just bypassing it with urea, formic et al). Hydrogen is a bear to store and to work with. And the reaction is costly enough - and necessary enough - it's contributing to energy use, competing with us schmoes who live here.

The new, cheaper plan is a catalyst: mix of iron oxide and an acid polymer with fluorine and sulfur. Humid air would pass through this mesh at room temperature (or warmer) and sea level pressure. And if supply-chains are at issue, farms in Iowa can buy this mesh and just make the ammonia right there in springtime.

And shipping can also run on ammonia, so it will be cheaper for them too.
