Project Summary

This project aims to develop novel solid sorbents using scalable nanoparticle synthesis and manufacturing technologies for the post combustion capture of CO2 from coal combustion flue gases. It will assess the performance of these sorbents using simulated flue gas across multiple capture and release cycles. Assessment will also be made of the performance of the sorbents on real flue gas across multiple capture and release cycles at pilot-scale.

Final Project Report on the outcomes of the project

The aims of this project were to evaluate the economic viability of post-combustion CO2 capture (PCC) based upon CaO-looping processes and to develop and produce tailored CaO-based CO2sorbents on a large scale.

Key findings of this research are:

• CaO looping can increase the net efficiency of a supercritical-coal-fired power plant.

• Improved CO2 sorbents can lower the variable operating costs of a PCC plant, but has a relatively small effect on the annualised cost of CO2 captured. However, if these sorbents lower the size requirements for equipment such as the calciner and carbonator, the impact may be greater.

• A techno-economic model for the retrofitting of a PCC plant onto an existing coal plant shows that capital costs are by far the largest contributor to a viable business case.
