Illustration of the solar-powered coupled photoelectrochemical and hydrogenation unit. The coupled device uses sunlight to generate hydrogen and consumes some of the generated hydrogen in situ to hydrogenate biomass-derived feedstock using a homogeneous catalyst. The remaining hydrogen can then be used for energy storage, transport, building and industrial applications. The hydrogenated products are valuable chemicals in high demand by the chemical and pharmaceutical industries. The fraction of the hydrogen used for the hydrogenation reaction can be adapted to demand by regulating the supply of biomass feedstock and the catalyst concentrations accordingly. By switching between "Feedstock A + Catalyst A" and "Feedstock B + Catalyst B", different hydrogenation products can be produced in the same PEC plant.
