Publication metadata
Chemical looping utilising metal oxide carrier has emerged as one of the very promising technologies with the potential to capture CO2 while maintaining high plant power generation efficiency. After validation of chemical looping for solid fuels at 10 kWth scale, the Éclair programme represents an important step in the development of the technology. The major goal of the programme is to address the key issues identified: Down selection of the best oxygen carrier material; Design and operation of upscaled test rigs: highly flexible rig (100 kWth) and full prototype (1 MWth); Upscaled product study. Potential alternative oxygen carriers have been evaluated. Some interesting options have been found but these need further studies and development to improve characteristics to fulfil requirements of industrial chemical looping unit. Significant operational experience has been successfully carried out in 0.5 to 10 kWth units. A 100 kWth rig has been successfully operated in stable conditions with different fuels and ilmenite as oxygen carrier. A 1 MWth prototype has been erected and operated for several weeks. Update of the concept for a 455 MWe CLC power plant has confirmed that chemical looping is well positioned compared to other technologies. In conclusion, the project has given a very substantial addition to the state of art when it comes to chemical-looping combustion of solid fuels. The results clearly indicate the viability of the CLC for solid fuel technology, which has the potential for high reduction of energy penalties and costs of CO2 capture.
