The technology behind innovation

The module uses the effect of photoelectrochemical catalysis to split water into hydrogen and oxygen. Unlike traditional electrolysers that use electric current to separate water molecules, this new module includes solar panels that increase the efficiency of the reaction.

The basis of the system is a catalyst made of almost ordinary glass sheet. By applying special materials to the glass by vacuum deposition, a nanometer-thick film is formed on both sides. The accuracy of such deposition, together with carefully selected semiconductor materials, significantly increases the efficiency of the catalyst.

How does it work

When sunlight hits the glass, short-wave radiation is absorbed on the outer surface, producing oxygen. At the same time, long-wave radiation penetrates the inner layer, producing hydrogen. A baffle separates these two gases, which are then collected separately.

A module with a working surface of 50 cm², scaled to an area of ​​100 m², can produce up to 30 kg of hydrogen per year. This amount of hydrogen is enough to refuel an average passenger car for a distance of 15,000 to 20,000 kilometers.

One of the key advantages of this development is its scalability. The compact modules can be easily scaled to meet different hydrogen production needs. This capability is crucial for expanding the application of the technology to larger industrial-scale hydrogen production facilities.

But not everything is so great

While the efficiency and innovation of photoelectrochemical catalysts are well documented, they have historically suffered from rapid degradation. Details of how the innovative modules overcome this problem have not been disclosed, but the research team is confident in the robustness and durability of their design.
