To promote synergies between circular bio-economy and various biomass uses to the fullest, only efficient biomass to energy conversion should receive public support, except for security of power supply. Financial support should focus on cost-effective methods for increasing energy efficiency, which would lead to a reduction in energy consumption. Actually, we have different energy efficiency thresholds for biomass conversion at the end, ranging from relative low efficiencies (η) for small scale seasonal space heating using logs (η = 30%) and large scale electricity production only (36%) to more efficient conversion pathways via seasonal space heating using pellets (65%), medium scale boilers (77%) and high efficient cogeneration (CHP). In a quick scan, the total solid biomass share by all EU households together was estimated at about 41% of total solid biomass consumption in the EU. This residential use can be split into about 4% via efficient pellet stoves and boilers and a remaining share of 37% for other, non-pellet based appliances like less efficient fire places and log boilers (η 30% or lower). Further, the solid biomass share of relative low efficient cofiring of pellets in powerplants (η around 40%), was estimated between 4%- 7% of total solid biomass use in 2017.
