2013/14 R&D Project Grants

Advanced Chemical Looping Project
$450,000 funding for 'Advanced chemical looping combustion technology for Victorian brown coals'; submitted by Monash University in association with Commonwealth Scientific and Industrial Research Organisation (CSIRO); Alstom Boiler, France; Energy Australia; VITO, Belgium (oxygen carrier manufacturer); and Lycopodium Process Industries Australia (engineering consultancy); Southeast University, China and University of Alberta, Canada.


This project extends earlier BCIA-funded research - the first known study of chemical looping combustion (CLC) and gasification of Victorian brown coal - as an emerging alternate technology for the capture of CO2 at a significantly lower energy and cost penalty.

A targeted focus of this research project is to advance the commercial prospects of this emerging technology through an evaluation of brown coal CLC performance under more continuous operating conditions, and to improve understanding of the longer term coal and oxygen carrier interaction effects.

Chemical looping has been widely studied for the combustion of natural gas but research into its potential application for solid fuels commenced only in recent years.

Utilising metal oxides as a major source of oxidising agent, rather than concentrated gaseous oxygen from air separation plants, the technology removes the energy and capital costs of air separation plants.

The initial BCIA-funded project systematically assessed various oxygen carriers for use with Victorian and international lignite samples and found that the low ash content, high reactivity and high oxygen content of Victorian brown coal is particularly suited to chemical looping.

The current project will extend this research through both bench-scale research and targeted experiments to be conducted in a Victorian purpose-built, compact fully looped and continuously fed reactor system.


The primary research objectives are to examine the feasibility of the CLC process in the continuously looping reactor, establish the techno-economics of a commercial scale brown coal CLC and develop a detailed process model for a commercial scale CLC plant.

The techno-economic evaluation will identify the greatest opportunities for reducing the cost of CLC carbon capture and ascertain where a commercial brown coal CLC plant can meet international carbon capture targets of above 90 per cent CO2 capture efficiency with less than a 35 per cent consequent increase in power generation costs.
