Hydrogen is emerging as the future of renewable fuels, with various
technologies for its production under development. Upon alternative
solutions, photocatalysis stands for its unique potentialities: reduced electric energy consumption, simple and robust reactors. Moreover, green hydrogen production is combined with purification of industrial wastewater, making this technology doubly appealing.
Currently, no commercial photocatalysis reactors for hydrogen production are available. Furthermore, the literature reports mainly photocatalysis
reactors performing water-splitting and does not use wastewater. The
PHOENIX project is indeed aiming at investigating the hydrogen cost of a photocatalysis pilot plant. In fact, before realizing an industrial-size plant, it is essential to establish on a smaller scale the competitiveness of the technology.
