CLYOSPHERE aims to demonstrate clean hydrogen production from the photothermal transformation of biomass-derived compounds, using solar light by integrating novel photoactive catalysts inside an innovative photoreactor based on solar Compound Parabolic Concentrator (CPC) configuration.

CLYOSPHERE will develop new photo(thermo)catalysts based on semiconductors (and their heterostructures) capable of absorbing in the UV, Vis and IR solar irradiation, and metal nanoparticles presenting plasmonic effect and integrated in 3D porous carbon bodies -materials with strong light absorbing features and thermal conductivity- inside the photoreactor, allowing also a perfect flow-through architecture with maximized solar absorption.

This configuration will allow solar irradiation to be concentrated to reach temperatures between 150-200 °C, and to perform the photo(thermo)reforming in vapor phase of aqueous biomass-derived compounds solutions to obtain clean hydrogen under a continuous feed.

CLYOSPHERE proposes a technological alternative to water electrolysis to produce hydrogen and simultaneously oxidize biomass waste derived compounds industrially generated in a water medium by a moderate temperature photo(thermo)photocatalytic solar-driven process.
