(525d) Performance Evaluation of Waste Biomass to Energy with Carbon Capture and Storage Systems

Waste biomass can be converted to electric power through waste-to-energy power plants and it plays a significant role in enhancing energy security and mitigating carbon emissions. When associated with carbon capture and storage (CCS), a critical low carbon technology to prevent the release of CO₂ to the atmosphere, the bioenergy with carbon capture and storage (BECCS) systems can potentially achieve negative carbon emissions. This study aims at comparing the technological feasibility and environmental impacts of two specific waste to energy conversion options with CCS, namely the use of agricultural residues such as corn stover in dedicated biomass conversion facilities, and municipal solid waste incineration. The analysis methods include environmental life-cycle analysis and techno-economics using a combination of data sources such as process model and literature data. This investigation will provide an analysis framework for waste-to-energy strategies and help identify the challenges and opportunities for waste biomass conversion and carbon emission reduction potential in China.
