Life Cycle Optimisation for Bio-energy Systems with Carbon Capture and Storage in Electricity Generation

Abstract

Bioenergy with carbon capture and storage (BECCS) has been identified as the most viable and cost-effective technology to achieving the 1.5°C targets set down in the 2015 Paris Agreement. It is essential to understand the impact of BECCS on carbon dioxide removal at a commercial scale. As such, this research presents an extensive life cycle analysis and optimisation of BECCS. To ensure the proposed methodology is appropriate for this research, case study of three cases is performed. In the case study, an existing coal-fired power plant is used as a base case for comparison between 2 different BECCS configurations. A regional assessment of the BECCS configurations from various critical performance aspects is then performed. This consists of assessing the system effectiveness, environmental impacts, energy efficiency, and cost optimisation from a life cycle perspective.
