So out of the 30 gigatons of CO2, up to 22 are from biomass? That's way, way more than I would have thought...

I think the 22 is not how much is currently emitted from biomass, it's the upper bound on how much we could store if we replaced a bunch of energy generation with this process.

I think the meaning is that out of the 30 gigatons of CO2, 22 gigatons can be recaptured ("negative emissions").

Right and that sounds like a lot to me. I hope they're right.
