The environmental benefit of blue hydrogen is that it doesn't put CO2 into the atmosphere. This is better than burning the hydrogen carbon gas it was produced from.
Except it does. This study suggests that the plants that produce hydrogen from fossil fuels are only capturing 80% of the CO2. So 20% is emitted. And aside from that hydrogen has the potential to contribute 12x as much to global warming as CO2 emissions.
That statement is correct, but you are still wrong. Blue Hydrogen specifically refers to hydrogen produced fron fossiles where the CO2 is captured. There is just very little blue Hydrogen being made from fossiles- most production is either grey Hydrogen (from gas no capture) or brown (same but coal).
