Chemical-looping combustion (CLC) has unique potential for reducing energy and cost penalty for CO2 capture, as it avoids the costly gas separation of other CO2 capture technologies. Early deployment is seen in natural gas steam generation, where gas-to-steam efficiency penalty with CLC is below 1%-point compared to 15%-points with amine scrubbing and 8%-points with oxyfuel combustion, all for 95% capture rate. Reduction of the CO2 avoidance cost of 60% compared to amine scrubbing post combustion capture results from higher efficiency. An absolute necessity for the scale-up of reactors for this technology is the availability of adequate oxygen carrier material. SUCCESS will assure scale-up of oxygen-carrier production to the 100 tonne scale, as well as scale up of technology to 1 MW. Industrially available raw materials will be used to produce environmentally sound oxygen carriers based on two highly successful materials developed of the previous INNOCUOUS project. The work includes,
i) applying the oxygen carrier production methods at industrially required scale and assuring the adequate performance,
ii) development of standard for mechanical stability,
iii) validation operation in four available smaller pilots <150 kW, of significantly different design
iv) operation with gaseous fuels in a 1 MW pilot plant, representing a scale up of the state of art by one order of magnitude.
v) detailed studies of reaction mechanisms and fluid-dynamics
vi) use of results in optimization of a previous design for a 10 MW demonstration plant and techno-economic study of full-scale plant
vii) assessment of health, safety and environmental issues associated with oxygen carrier handling including reuse or recycling strategies.
viii) quotations for production of >100 tonnes of material
Combined efforts of key European developers of CLC technology will assure the continued European leadership in this development and bring the technology a major step towards commercialization.
