Publication Overview

This report reviews existing work on the operating flexibility of power plants with CO₂ capture, discusses techniques which could be used to assess flexibility and proposes further work that could be undertaken on this subject. Operating flexibility of power plants is likely to become more important in future as more renewable power systems with variable outputs are built to reduce CO₂ emissions. Operating flexibility could be a significant factor in the choice of the optimum CO₂ capture technology and it may also affect the extent to which CCS will be used in future.

Publication Summary

Operability is an important consideration for power plants operators and it is likely to become even more so in future due to the increased use of renewable energy sources with low-CO₂ emissions. It could be a significant factor in the choice of the optimum CO₂ capture technology and it may also affect the extent to which CCS will be used in future.

There is currently little published work on operability of power plants with CCS.

The amount of effort required for detailed analysis of the operability of power plants with CCS would be substantially greater than that of IEA GHG’s other technical studies. For such a study to go ahead addition funding would be needed, for example from any IEA GHG Members and Sponsors that are especially interested in this subject.

A Technology Level Assessment of Efficiency, Cost, and Scale of Net Zero Aligned Energy Technologies for Electricity or Hydrogen Production & Unpacking Uncertainty in Net Zero Techno-Environ-Economic Assessment

  • 17 September 2026
  • Capture
  • Costs of CCUS

Forty-four electricity and hydrogen configurations, from CCGT and BECCS with CCS to nuclear, hydropower and VRE paired with battery, pumped hydro or hydrogen storage, are compared on process efficiency, levelised cost, deployment scale and life-cycle environmental performance, alongside an uncertainty analysis showing how capacity factor, CAPEX, carbon and CDR prices, and location can reorder the results.

Techno-Economic Assessment of Small-Scale Carbon Capture for Industrial and Power Systems

  • 1 March 2024
  • Capture
  • Costs of CCUS

This study, undertaken on behalf of IEAGHG by Element Energy (now a part of ERM), explores the role of CCS in decarbonising small-scale industry and power generation applications. While relatively under investigated compared to their larger scale counterparts, reaching net zero will be dependent on successfully addressing the emissions from small-scale facilities. The findings from the study will be of interest to the broader energy community but, in particular, should benefit project developers, the finance community and policymakers.
