Retrofitted carbon capture and storage for negative emissions in China’s co-firing plants – Nature Climate Change

Assessment of Carbon Dioxide Emissions Reduction Potential from Coal-Biomass Co-firing Power Plants with Retrofitted Carbon Capture and Storage in China

We have established a comprehensive assessment framework to explore the carbon dioxide (CO₂) emissions reduction potential from coal-biomass co-firing power plants with retrofitted carbon capture and storage (CBECCS) in China. The optimal spatiotemporal deployment of the CBECCS transition could achieve a CO₂ mitigation of 1.6 Gt yr⁻¹ in 2040 and 41.2 Gt cumulatively over the period 2025–2060.

Analysis

The article discusses the potential for reducing carbon dioxide (CO2) emissions through the retrofitting of coal-biomass co-firing power plants with carbon capture and storage (CBECCS) technology in China. This aligns with SDG 13: Climate Action, which aims to combat climate change and its impacts.

The specific target addressed in the article is Target 13.2, which focuses on integrating climate change measures into national policies, strategies, and planning. The article explores the potential for CO2 mitigation through the deployment of CBECCS technology in China’s power sector.

The indicator mentioned in the article is the reduction in CO2 emissions. The study estimates that optimal deployment of CBECCS technology could achieve a CO2 mitigation of 1.6 Gt per year in 2040 and 41.2 Gt cumulatively over the period 2025-2060.
