Item 1. Business. Unless otherwise stated or the context requires otherwise, references in this annual report on Form 10-K to "SunHydrogen", the "Company", "we", "us", or "our" refer to SunHydrogen, Inc. Overview At SunHydrogen, our goal is to replace fossil fuels with clean, renewable hydrogen. Hydrogen is the most abundant chemical element in the universe. When hydrogen fuel is used to power transportation and industry, the only byproduct left behind is pure water, unlike hydrocarbon fuels such as oil, coal and natural gas that emit carbon dioxide and other harmful pollutants into the atmosphere. However, naturally occurring hydrogen molecules are rare – so rare that today about 95% of all molecular hydrogen is produced from steam reforming of natural gas (Source: US Department of Energy, Hydrogen Fuel Basics). This process is both economically and environmentally unsound. SunHydrogen is developing an efficient and cost-effective way to produce truly renewable hydrogen using sunlight and any source of water. Our innovative solar hydrogen technology uses abundant and low-cost materials, requires no external power other than sunlight, and is designed with scalability in mind. Its core components include a substrate, photovoltaic layers, stabilization coatings, and catalysts that integrate to split water molecules into renewable hydrogen and oxygen. Just like a solar panel is comprised of multiple cells that generate electricity, our hydrogen panel encases multiple hydrogen reactors immersed in water. Each hydrogen generator autonomously splits water into hydrogen and oxygen. We believe our technology has the potential to be one of – if not the most – economical renewable hydrogen solutions: Unlike traditional water electrolysis for hydrogen, our process requires no external power other than sunlight and uses efficient and commercial-proven materials. We believe renewable hydrogen has already proven itself to be a key solution in helping the world meet clima
