Except you've actually debunked your own argument.
At 9.3 kg of CO2 for one kg of H2, and assuming 110 km/kg of H2 (normal fuel economy for an FCEV), you get 84.5 grams of CO2 per km of driving.
Meanwhile, a BEV gets anywhere from 70-370 grams per km, depending on dirtiness of the grid: https://shrinkthatfootprint.com/electric-car-emissions/
In other words, an FCEV is comparable to a BEV when it comes to emissions. You can even double the numbers for the FCEV if you want to include possibilities like upstream losses or production. The numbers would still be very comparable to BEVs running on most grids.
And this is the problem here: You're so deep in your anti-hydrogen conspiracy theory that you failed to notice that the math works against you.
