A Dimensional Analysis for Cost Optimization and Cost-Effective Carbon
Capture: A Comparative Study of Hybrid Post-Combustion Configurations in
Natural Gas Power Plants
Abstract
Carbon capture, utilization, and storage (CCUS) considered a key
strategy for reducing the emissions of anthropogenic carbon dioxide from
power generation plants, can be achieved by three main technologies:
oxy-fuel combustion, pre-combustion, and post-combustion capture.
Post-combustion carbon capture (PCC), where CO2 is removed after the
fuel burning, is a crucial solution for reducing greenhouse gas
emissions from natural gas power plants (NGPPs). However, high costs and
energy penalties associated with PCC technologies hinder their
widespread adoption. Recent advancements in hybrid PCC configurations
have shown promise in improving efficiency and reducing costs. In
effect, six PCC hybrid configurations below were identified as feasible
process routes:
