A new autothermal route to produce hydrogen from natural gas via chemical looping technology was investigated. Nowadays, 90% of the worldwide produced hydrogen comes from fossil fuels, the most common process being Steam Methane Reforming (SMR), which produces several kg of CO2 equivalent per kg of hydrogen. In classic SMR technology, most of the greenhouse gases are vented to the atmosphere. Chemical Looping Combustion (CLC) is a promising concept based on circulating fluidized beds to combust solid, liquid and gaseous fuels with inherent CO2 capture and minimal NOx formation. Chemical Looping Reforming (CLR) utilizes similar principles as CLC but the objective of CLR is hydrogen, as opposed to energy for CLC.
