About us
PH2OTOGEN aims to create a scalable device that uses sunlight to make clean hydrogen and other valuable products that can generate revenue for the overall system. The project, co-funded by the European Union and supported by the Clean Hydrogen Partnership and its members, gathers 8 partners from 5 countries.

2025-06-27 | Scale up of the transparent, conducting, porous support
To demonstrate the PH2OTOGEN device concept, a robust, transparent, and porous substrate for the photocatalyst particles is needed. WP4 is dedicated to this task. SiO2 fibres, selected for their transparency and mechanical robustness, are processed to form a monolithic semi-transparent scaffold sheets over 100 cm² in area.

2025-06-26 | Organic photoabsorber layer of the photocathode
The PH2OTOGEN demonstrator uses a photoabsorber layer consisting of organic semiconductor materials to capture light in the H2-evolving photocatalyst sheet. The selected materials are typically used in organic solar cells.

2025-06-25 | The PH2OTOGEN project aims at utilising sunlight to produce green hydrogen from water while oxidising low-value organic molecules, such as glycerol, into valuable chemicals
We are now designing a first small-scale version of the photoreactor. This first version will be able to accommodate active photocatalytic sheets of ~5 cm2 and will allow us to test the feasibility of our process before scaling it up to 500 cm2.
