Bioenergy carbon emissions footprint considering the biogenic carbon and secondary effects

Popis výsledku v původním jazyce

The sustainability of bioenergy is varying on a case-by-case basis. It considerably depends on the source of biomass, management practices (plantation, harvesting, conversion technologies, supply chain, etc.) as well as the assessment boundary and assumptions. This study summarises the carbon emissions footprint (CF) flow of bioenergy by considering the possible sources and system boundary, particularly on the CF of biogenic carbon and secondary effects. The assessment framework has been applied to a demonstrated case study identifying the upper limits of global warming potential of biogenic carbon emission (GWP(bio)) and secondary effects contribution where the bioenergy is still superior to the coal, natural gas and gasoline. The circumstances where the other energy source alternatives could have a lower CF than bioenergy are highlighted. For example, coal and natural gas are the selection (lower CF) if the bioelectricity is subjected to the GWP(bio) higher than 0.57-0.74 and 0.18-0.34. CF of bioheat is higher than the heat generated by natural gas when the GWP(bio) is more than 0.04-0.40. Gasoline is the selection when the GWP(bio) of biofuel is higher than 0.12-0.42. The validity of carbon neutrality assumption of bioenergy possesses a more decisive role in the overall selection of bioenergy compared to the assessed secondary effects such as soil organic carbon changes. This study emphasises the importance of a rigorous CF accounting for bioenergy to support the equitable decision making.
