To address the problem of unavoidable process CO₂ emissions associated with the production of lime, efficient capture technologies need to be developed and implemented. The indirectly heated carbonate looping (IHCaL) process is an efficient candidate for this application because it utilizes lime as the sorbent for the CO₂ capture. In this work, a retrofit configuration of this process is presented and analyzed for net negative CO₂ emissions. This is done considering different fuels that provide the heat required for the regeneration of the sorbent.
