The HyperSolar H2 generator passes all the tests: 294 hours of hydrogen by stable photoelectrolysis of water and that’s just the start. New record in the production of ecological hydrogen.

France’s new energy plan proves it: the hydrogen economy is no longer a dream to put in a drawer. This device can be integrated into energy systems at several levels to help the process of decarbonization of industries, communities and power plants or heat.

For this to happen, however, there are still a number of hurdles to overcome in terms of profitability in this production technology. If the hydrogen in question is “green”, that is to say obtained by electrolysis of water supplied by renewable energies, there are essentially two challenges to be met: the efficiency of the process and the degree of purity. of the water itself.

Electrolytic systems lose part of the energy during production, and only a fraction of the electrical energy is, so to speak, “stored” in hydrogen molecules. This results in a high production cost. Additionally, conventional electrolysis requires highly purified water to prevent fouling of system components. In other words, an additional energy expenditure.

One solution could be HyperSolar, a California-based company that has engineered technology that can use even urban wastewater to achieve unlimited production of renewable hydrogen.

To solve the problem of efficiency, the company has developed a nanoscale system that allows the direct introduction of photovoltaic elements into the water for direct electrolysis, avoiding corrosion and short circuits. “By dealing with the science of electrolysis at the nano level, we believe that our nanoparticle technology can deliver unprecedented cost savings to enable the commercial production of renewable hydrogen from any source of water, with the sunlight as the only source of energy.ยป, Explain the inventors.

And the tests that have been done have shown that the Hypersolar technology works. The device exceeded 294 hours of stable hydrogen production, under simulation of continuous sunlight, without any degradation. “Use of a new coating technique with a protective polymer layer that encapsulates the entire device -explained Joun Lee, CTO of HyperSolar- we were able to exceed the April results (100 hours) and we are much closer to our goals of 1000 hours of continuous stable operation. “
