A Sustainable Pathway of Bioenergy with Carbon Capture and Storage Deployment.

We present a development strategy of low carbon scenarios that consider interaction of economically viable bioenergy and/or BECCS technological flow, biophysical limit of bioenergy productivity and food security. In the process, detailed bioenergy representations, including various bioenergy feedstock and conversion technologies with and without CCS, are implemented in an integrated assessment (IA) model, GRAPE (Global Relationship Assessment to Protect the Environment). Also to overcome a general discrepancy about yield development between ‘top-down’ IA models and ‘bottom-up’ estimates, we applied yields change of food and bioenergy crops consistent with process-based biophysical food crop models for bioenergy crops in changing climate conditions. Using the framework, economically viable strategy for implementing sustainable BECCS are evaluated. [ABSTRACT FROM AUTHOR]
