Chemical Looping Combustion (CLC) is a relatively new method for combustion of fuels for power production with very low CO₂ capture cost. The reason for this is that the oxygen is fed into the combustion chamber in the form of a metal oxide that is able to release oxygen and give a full combustion forming CO₂ and H₂O. The water is then condensed and the CO₂ can be compressed and sent away for storage. The material is looped between the fuel reactor where it looses oxygen and the air reactor where it takes up oxygen from air and creates heat. The heat from both reactors is used to produce electricity either in a gas turbine or a steam turbine all depending on the process. The strength of this technology is that it can be used on nearly all kind of fuels.

SINTEF has long experience working with functional ceramics for different applications. This knowledge is used in CLC projects to formulate oxides with properties that gives the best results.
