Abstract

We report on results regarding the annual average efficiency of a recuperating packed particle bed reactor for solar-thermochemical hydrogen production via a two-step metal oxide cycle, using detailed numerical models. The key findings are that reactor efficiency is substantially flat as a function of direct normal irradiance, leading to an annual average efficiency almost equal to the design-point efficiency, and that ample high quality waste heat is available to make standalone operation feasible, including feedstock water production. This conclusion has far-reaching implications for solar-thermochemical hydrogen and fuel production in general.
