RELCA V.1 - LCA for Regional Bioenergy systems
Through collaborative work with the DBFZ and CLE department (UFZ), regionally distributed databases were established. These were then used to form the basis modelling for the succeeding modelling steps.
CRAM (Wochele et al. 2014) produces the potential biomass availability for the different regional bioenergy plants. CAM modelling in collaboration with the DBFZ determines, based on regional data, the appropriate and regionally representative model plant concepts and hence the biomass demand functions for the CAM modelling. The CAM modelling links the technology concepts with the biomass availability and thus provides the spatially distributed life cycle inventory (catchment delimited) for each model plant concept within the region.
Other modelling components currently under construction enable the modelling of potential field GHG emissions. Thus RELCA V.1 provides the framework for a hybrid LCI of bioenergy conversion systems within a regional case study area, in order, as a first step to conduct a retrospective LCA to investigate the status quo of the potential environmental implications for the regional production of different energy products. Currently LCA software is implemented to integrate the regional foreground burdens with the assumed non-regional environmental burdens.
