I don't know how the infrastructure works for biomass, but open pit coal mines in the US are extraordinarily efficient when management isn't fucking them up. We're talking electric conveyor systems that span from pit to plant, diesel-electric haul trucks, and a rail loop that drives right under the plant for loading onto a train that will net about 15-17k tons and ship "directly" to the generator. A coal seam can last a real long time depending on demand. And the infrastructure is already there and has been for ~50 years with various optimizations added along the way - at least in my locale.
I'm under the impression that logging is far less efficient due to the nature and complications of the work, but that is, I admit, simple conjecture: You're constantly moving, maybe with some gravity assist, to transport and load the raw material, I imagine for packing efficiency they're chipping straight into a 53' trailer, which will then port a relatively small sum, about 21-22.5 tons, compared with a haul truck, which range from 153-410 tons for back-and-forth movement. If we consider this holistically, BTU/man, BTU/manhour should both be accounted for as well, since those are real inputs which at scale (I imagine) represent a pretty substantial expense in terms of CO2.
Coal is also "processed" on site, with pretty minimal input: being crushing, drying, and sometimes spraying. There aren't secondary and tertiary processes.
Energy from PRB coal, at the minimum of my data is about 7,420 BTU/lb. Some dry wood can "compete" at this level, apparently, when dry in fact one data point indicates 9033 BTU/lb (Colorado Pinyon). Maximum mean BTU for coal in the PRB is 11k (compared to 8.2 kBTU/lb pellet). I say compete because from what I've heard, generator designs aren't indiscriminate and require certain energy densities to hit efficiency - which may be a benefit of biomass because there's a lot more control, I'd imagine, in pelletizing wood vs. coal, which is a simple mix-batch. At scale it might actually be a pretty considerable boon for biomass.
To me this reads that biomass is going to require more input to extract the same amount of energy. The processing to get biomass to similar energy density is going to require more energy input. But even the primary input, knocking trees over, chipping them, porting them, is going to be less efficient and less centralized, and even once it does culminate in some logistical knot... You said it yourself, it sucks. But also, deforestation sucks. So does human sprawl.
My point here is that I do think the idea that burning wood is "carbon neutral" is spurious, because there are a lot of points which fossil fuels are used, and used less efficiently, and that the process at least by my imagination is ultimately less efficient, and those losses will also inevitably contribute to increases in the CO2 chain which I think is largely ignored. Maybe it's more like slightly-less carbon - cause the whole "if it's wood and we burn it now and let it grow back later while we keep cutting more and more down to satisfy the constantly increasing energy demands..." reads like we're displacing consequences into the future.
But! This is with the caveat that I'm not particularly familiar with the processes of biomass fuel production chain, and that my calculations are based on US information and doesn't necessarily pertain to industries in the EU.
