Title

Solar Concentrator Options For A Thermochemical Hydrogen Production Process

Abstract

Science Applications International Corp. (SAIC) and the Florida Solar Energy Center (FSEC) of the University of Central Florida have teamed to develop an advanced solar thermochemical water-splitting cycle for hydrogen production that utilizes the "quantum boost" effect of sunlight. The objectives are to cost-effectively generate hydrogen at above 40% efficiency. The process is unique in that it utilizes "quantum boost" to photocatalytically operate a hydrogen production sub-process. By employing quantum boost, the high-energy photons of the solar spectrum are used rather than thermalized, and the energy requirements of the high-temperature portions of the cycle are reduced. Because the photocatalytic reaction only uses the ultraviolet/visible portion of the solar spectrum, it has been proposed to split the solar beam into high-energy photons and thermal radiation using hot or cold mirrors or other approaches. SAIC has been investigating solar field configurations appropriate to supply solar energy to these processes including heliostat/central receiver, parabolic dishes, and other geometries. This paper provides an evaluation of potential collector and reactor configurations.
