Bioenergy with carbon capture and storage (BECCS) – power generation coupled with hydrogen production

Achieving Net Zero emissions by 2050 requires the utilization of negative emissions technologies such as Bioenergy with Carbon Capture and Storage (BECCS), as well as hydrogen to decarbonize challenging industrial CO2 emitters. Within this paper we develop a BECCS-Power-Hydrogen process model in Aspen Plus. The analysis shows the key operating parameters and key performance indicators for the process. The base case electrical efficiency is very low (18.4%) but including the hydrogen production increases the overall system efficiency to 52%. Also included in this study is a sensitivity analysis investigating the effect gasification temperature has on the hydrogen production and net system efficiency.
