Carbon Capture in Power Plants
Research Guide
What is Carbon Capture in Power Plants?
Carbon capture in power plants deploys post-combustion, pre-combustion, and oxy-fuel technologies to separate CO2 from flue gases in coal and gas-fired plants before atmospheric release.
Research focuses on amine absorption solvents, membranes, and oxycombustion processes integrated with existing fossil infrastructure (Perrin et al., 2014; Huertas et al., 2011). Over 20 papers in the provided lists address CCS deployment challenges, with foundational works exceeding 60 citations each. These technologies support net-zero transitions by retrofitting power plants.
Why It Matters
Carbon capture enables continued operation of coal and gas plants while slashing emissions, bridging to full renewables (Sepulveda et al., 2018; Perrin et al., 2014). In Europe, CCS integration with biogas upgrading via amine absorption cuts CO2 and H2S, enhancing grid stability (Huertas et al., 2011; van Foreest, 2012). Real-world projects like oxycombustion pilots demonstrate 90% capture rates, reducing deployment costs for 2050 decarbonization (Perrin et al., 2014; Nagaj et al., 2024).
Key Research Challenges
High Energy Penalty
Capture processes consume 20-30% of plant output, raising electricity costs (Perrin et al., 2014). Optimizing solvents and heat integration remains critical (Huertas et al., 2011). Over 77 cited works highlight this barrier to scale-up.
Integration Costs
Retrofitting fossil plants adds billions in capital expense, delaying CCS rollout (Sepulveda et al., 2018). Economic models show policy needs for viability (Skoczkowski et al., 2018). Citation analyses reveal persistent funding gaps.
Solvent Degradation
Amine solvents degrade under oxy-fuel conditions, requiring robust alternatives (Perrin et al., 2014). Biogas CO2 removal faces similar issues with H2S impurities (Huertas et al., 2011). Research gaps persist in long-term stability.

Frequently Asked Questions
What is carbon capture in power plants?
It uses post-combustion amine scrubbing, pre-combustion shifting, or oxy-fuel combustion to isolate CO2 from flue gases in coal/gas plants (Perrin et al., 2014).
What are main CCS methods?
Oxycombustion burns coal in O2/CO2 mix for easy separation (Perrin et al., 2014, 77 citations); amine absorption removes CO2 from biogas/power exhaust (Huertas et al., 2011).
What are key papers?
