Bioenergy and bioenergy with carbon capture and storage (BECCS) technologies can achieve zero or even negative CO2 emissions, hence have been considered as one of the essential technologies in achieving the 2-degree climate target. With ambitious climate policy, the demand for bioenergy would be up to 200-300 EJ per year based on recent predictions. At this level, a large volume of biomass is needed to generate energy. In order to enhance the simulation performance in bioenergy crop yield, we modified the algorithm and adjusted parameters of a state-of-the-art global hydrological model termed H08. Overall, overestimation or underestimation seen in the original H08 have been largely suppressed in this enhanced H08, which performs much better in simulating yield of Miscanthus and Switchgrass. Results also showed that irrigation significantly increased the yield for both Miscanthus and Switchgrass especially under dry climate condition.
