Development of metal oxides Chemical Looping process for coal-fired power plants

1 figure, 1 scheme.-- Talk delivered in the IEA GHG, 3rd Oxyfuel Combustion Conference, Ponferrada (Spain), 6th -13th september 2013.Power generation is one of the biggest sources of man-made CO2 emissions. Significant research is underway to develop efficient low cost capture technologies. A number of novel technologies for both new and retrofit to fossil power plants have been conceived and are under development to offer greatly improved economics for carbon capture. Among the promising long term ideas currently being investigated are chemical looping technologies. A major advantage associated with chemical looping technologies is that oxygen is supplied to the combustion process without the large efficiency penalty and investment cost associated with a cryogenic type Air Separation Unit (ASU)
