To your comparison: Hydrogen only releases water if burned.
And getting CO2 out of air is very resource intensive and we need to pull a lot CO2 out, if the air to get back to “normal” levels. We can not afford to put any CO2 back into the atmosphere, after the hard work getting it out.

It is renewable, the power generation around that to create the hydrogen also needs to be renewable ofcourse like solar or wind. But the creation and use of hydrogen is a perfect chemical cyclus
