Hydrogen as a fuel is a nice dream and a technical capability we have mastered. The physics and thermodynamics and chemistry to generate hydrogen are immutable and require more energy input than the output from the end product. Hydrogen gives other problems in the transport and storage so the best scenario is onsite generation. These limit the practical use of hydrogen. The cost to use hydrogen to replace other fuels is an uneconomic effort. To propose that we could replace existing fuels with hydrogen is simply an uneducated proposition at best, but mostly a tail chasing exercise.
Frontieras North America says their process for cracking coal produces hydrogen as one of 8 useful products, and they'll use that H2 on site to further fuel their own operation. They mention H2O as another byproduct (from burning the H2?) so it sounds like they'll condense the water vapor - not putting it into the atmosphere - see Chris' comment below.
I would add that burning hydrogen releases water vapor to the atmosphere. WV is a GHG capable of accelerating the small warming from co2 (at least that’s the hypothesis)
Here’s a fact: virtue signalling has never been shown to work
Facts are stubborn things.

Sounds very promising.
