RELCA: a REgional Life Cycle inventory for Assessing bioenergy systems within a region

摘要: The last decade has seen major development and adoption of bioenergy, particularly in Germany. This resulted a scattering decentralised bioenergy plants across the landscape, due to their dependency on spatially diffuse biomass resources. Regional conditions (e.g., soils, climate, management) influence environmental burdens resulting from production thus, also effect performance production. Therefore, more regionally focused life cycle approaches are required for assessing these systems. aim this paper is outline such an approach. “RELCA”, regional inventory spatial variation within region. Five modelling steps combined form RELCA approach order determine: (1) crop allocation, (2) management, (3) representative plant models, (4) catchments, (5) indirect upstream emissions (non-regional) associated with challenges options each five outlined. Additionally, simple example provided using greenhouse gases (GHG) show how can be used identify potential distribution product (e.g. biodiesel) An combining distributed technologies, through use catchment delineation was developed. enabled introduction greater details As first “proof concept,” GHG were estimated example, illustrating (direct indirect) producing product. (v1.0) powerful scoping approach, which investigate region delineation. not without its limitations. Despite these, it still provides good starting point further discussion, improvements, developments implications as impacts soil, water, biodiversity) context .
