Abstract: Application of renewable fuel，especially hydrogen，is an efficient way to fight against the climate change and reduce the emission of the pollutants from the transport sector. Hydrogen production using chemical looping technology is a potential method for hydrogen production，which not only can improve energy conversion efficiency and reduce environmental pollution，but also can separate carbon dioxide，which shows good economic efficiency and promising future. This paper introduces two different approaches to produce hydrogen using chemical looping technology. The present development statuses on the screening of oxygen carrier particles，the design of proper reactors，and the system simulation for each approach are summarized respectively. The screening and preparation of proper oxygen carriers is the basis of successful operation in each process. The potential erosion of the reformer tubes by the oxygen carriers in CLR(s) process and the heat balance between the FR and AR in CLR(a) process need to be considered. The development of oxygen carriers with low price，and the design of proper reactor and the coupled system for solid fuel will be the main focus of CLH study.
