That only counts if you grow the trees explicitly for power generation. Burning trees that already existed (as is the plan for the plant I mentioned) is like burning coal, which also removed CO2 from the air in the past.

Trees are part of the active carbon cycle. They grow while taking in CO2, then die and rot while releasing it again. Burning them does the same thing as the second one, which was going to happen on its own.

Coal isn't part of the active carbon cycle. It would stay locked in the ground indefinitely if you didn't dig it up.

Moreover, that plant appears to be getting biomass as compressed pellets from sawmill scrap wood and sawdust, i.e. it's the refuse from trees that were already being logged to make lumber. If they didn't burn it then it would go into a landfill to rot and release the carbon anyway.
