4. Conclusion

As CO ₂ capture represents a non-negligible cost, particularly in fossil-fuel power plants, it seems that "Chemical Looping" technology is a cost-effective solution compared with other approaches proposed to date. Although further development work is required, this technology looks very promising and future commercialization is expected.

Chemical Looping" technology using gaseous fuels has been successfully demonstrated on a large number of small-scale pilots enabling electricity to be generated with interesting efficiencies and CO ₂ capture potential. This is the fruit of a great deal of work carried out in collaboration between industries and universities around the world over many years. However, to compete with the efficiency of natural gas-fired combined-cycle power...
