The cyclic calcium oxide‐calcium carbonate (CaO‐CaCO 3 ) process is a promising option for large‐scale CO 2 control. Important advantages include high‐temperature operation, inexpensive sorbent feedstock, and high CO 2 capture capacity of CaO. However, decreasing sorbent reactivity over multiple cycles, due to high‐temperature sintering, presents a major challenge for further progress. The Ohio State University (OSU) has led the development of a novel three‐step calcium looping (CaO‐Ca(OH) 2 ‐CaCO 3 ) process for post‐ and precombustion CO 2 capture. An overview of OSU's work is provided, highlighting the differences in this approach when compared to competing efforts in this field.
