In HICE engines, the emissions are a microscopic amount of NOx fumes, in a different world from existing gas or diesel engines.
Much less NOx, and we already have technology to reduce NOx for gasoline or diesel engines. Even better, because what usually hurts the systems used to reduce NOx is soot from the exhaust. There will be almost none of that on a hydrogen engine.
