A novel technology for making green hydrogen using the energy of sun light (photons) was invented. The technology includes a novel design of photo-reactors and photo-catalyst. The photo reactors are solar panels filled with especially-made semiconductor powder (the photo-catalyst) and lined with a liquid-gas separation sheet. When water, or other hydrogen-containing liquids, are pumped through the photo reactor, it becomes in contact with the photo-catalyst and thus, hydrogen is chemically released and immediate separated from via the separation lining sheet. This technology is protected by a pending patent and has the potential to significantly reduce the cost of green energy.
