Inflatable non-imaging solar concentrator powered high temperature thermo-chemical reaction system

An inflatable non-imaging solar concentrator powered high temperature thermo-chemical reaction system comprises:

• 1) an inflatable non-imaging solar concentrator with a transparent cover and a Compound Parabolic Concentrator (CPC);
• 2) the first stage of the multi-stage non-imaging non-tracking solar concentrator with a domed divergent Fresnel Lens transparent cover and a CPC;
• 3) the second stage of the multi-stage non-imaging non-tracking solar concentrator with a domed divergent Fresnel Lens transparent cover and a CPC;
• 4) a high temperature thermo-chemical reactor with a steel high pressure vessel, an insulation layer, a first CeO2 catalyst layer, and a second CeO2 catalyst layer;
• wherein, the inflatable non-imaging solar concentrator with a transparent cover and a Compound Parabolic Concentrator (CPC) is positioned on the top of the system, and then the first stage of the multi-stage non-imaging non-tracking solar concentrator with a domed divergent Fresnel Lens transparent cover and a CPC and the second stage of the multi-stage non-imaging non-tracking solar concentrator with a domed divergent Fresnel Lens transparent cover and a CPC are connected into a cascaded concentrator optical waveguide to guide the concentrated sunlight onto the high temperature thermo-chemical reactor with a steel high pressure vessel, an insulation layer, a first CeO2 catalyst layer, and a second CeO2 catalyst layer;
• when in operating, incident sunlight including beam light and diffuse light is firstly concentrated by the inflatable non-imaging solar concentrator in a large scale and an extremely low cost, then the multi-stage non-imaging non-tracking solar concentrator including the first stage solar concentrator and the second stage solar concentrator further concentrate the diffuse sunlight concentrated by the inflatable non-imaging solar concentrator to reach a ultra-high concentration ratio which is normally over 1000 suns, finally the concentrated sunlight is coupled into the thermo-chemical reactor including the steel vessel, the insulation layer, the first CeO2 catalyst layer, and the second catalyst layer to generate high temperature normally over 1000° C.;
