The HyperSolar H2 Generator device passes all tests: 294 hours of hydrogen per stable photoelectrolysis of water and it is just the beginning. 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 away in a drawer. This device can be integrated into multi-level energy systems to help the decarbonization process of industries, communities, and electricity or heat generation plants.
For this to happen, however, a number of obstacles still have to be overcome in terms of profitability in this production technology. If the hydrogen in question is “green”, that is, obtained by electrolysis of water fed by renewable energies, there are essentially two challenges to face: the efficiency of the process and the degree of purity of the water itself.
Electrolytic systems lose some of the energy in production, and only a fraction of the electrical energy is, so to speak, “stored” in hydrogen molecules. This results in a high cost of production. Furthermore, 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 Californian company that has designed a technology capable of using 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 water for direct electrolysis, avoiding corrosion and short circuits. “ By handling the science of electrolysis at the nano level, we believe that our nanoparticle technology can provide unprecedented cost savings to enable commercial production of renewable hydrogen from any water source, with sunlight as the sole source of energy “, Explain the inventors.
And the tests that have been conducted have shown that the Hypersolar technology works. The device surpassed 294 hours of stable hydrogen production, under simulation of continuous illumination from the sun, without any degradation. “ Using a new coating technique with a protective polymer layer that encapsulates the entire device, ” explained Joun Lee, HyperSolar’s CTO, “ we were able to exceed the results of April (100 hours) and we are much closer to our goals, namely , 1000 hours of continuous stable operation . “
