    SunHydrogen Reports Progress on its Nanoparticle-Based Green Hydrogen Technology

    SANTA BARBARA, CA – June 1, 2021 - SunHydrogen, Inc. (OTC:HYSR), the developer of a breakthrough technology to produce renewable hydrogen using sunlight and water, today announced progress on the development process for the scale-up of its nanoparticle hydrogen generation technology.

    Earlier this year, the company announced its cooperation with Schmid Group in Freudenstadt, Germany and InRedox in Longmont, Colorado to develop its technology to commercial scale. Schmid is developing the process and equipment for manufacturing while InRedox is focused on the electrochemical process of creating nanoporous templates on transparent substrates for growing nanoparticles.

    Despite foreseen challenges in the supply chain for necessary materials and equipment, the company has made positive progress in testing and confirming the scalable potential of the transparent substrates, a critical component for fabricating nanoparticle hydrogen generators. The company has worked with various transparent substrates to determine the best-performing ones for creation of nanoporous layers, which will then serve as a template and foundation for growing the nanoparticles. The company is further moving toward testing the growth of nanoparticles on the down-selected substrates at scales relevant for mass manufacturing.

    The company is also making good progress in the acquisition of the equipment and chemicals for fabrication, testing and validation of large-scale devices. The devices will consist of arrays of billions of nanoparticle-based hydrogen generators, each able to split water molecules into hydrogen and oxygen. Each array will be approximately the size of a single six-inch silicon solar cell.

    “InRedox and Schmid have been dedicated in providing the necessary input and support for the development process. They have pushed the project hard even with the challenges in supply chains due to persisting pandemic,” said Tim Young, CEO of SunHydrogen, Inc. “With the team in Germany now in place, and the necessary equipment now able to be obtained, we expect to see more rapid progress very soon.” Due to the delays associated with supply chain challenges, the Cooperation Agreement with Schmid has been extended to fully complete the work scope with no additional cost to the company.

    SunHydrogen zou de oplossing zijn voor de kreet: "The goal: hydrogen through solar energy"

    Producing Hydrogen Using Less Energy
    June 22, 2021

    The international research team describes the complete reaction path for electrocatalytic hydrogen generation

    The way in which a compound inspired by nature produces hydrogen has now been described in detail for the first time by an international research team from the University of Jena and the University of Milan-Bicocca. These findings are the foundation for the energy-efficient production of hydrogen as a sustainable energy source.

    Nature as a model

    There are naturally occurring microorganisms that produce hydrogen, using special enzymes called hydrogenases. “What is special about hydrogenases is that they generate hydrogen catalytically. Unlike electrolysis, which is usually carried out industrially using an expensive platinum catalyst, the microorganisms use organometallic iron compounds,” explains Prof. Wolfgang Weigand from the Institute of Inorganic and Analytical Chemistry at the University of Jena. “As an energy source, hydrogen is naturally of great interest. That’s why we want to understand exactly how this catalytic process takes place,” he adds.

    In the past, numerous compounds have already been produced worldwide that are chemically modelled on the naturally occurring hydrogenases. In cooperation with the university of Milan, Weigand and his team in Jena have now produced a compound that has yielded entirely new insights into the catalysis process. “As in nature, our model is based on a molecule that contains two iron atoms. Compared with the natural form, however, we changed the chemical environment of the iron in a specific way. To be precise, an amine was replaced by a phosphine oxide with similar chemical properties. We therefore brought the element phosphorus into play.”

    Detailed insight into electrocatalytic hydrogen production

    This enabled Weigand and his team to better understand the process of hydrogen formation. Through autodissociation, water forms positively charged protons and negatively charged hydroxide ions. “Our goal was to understand how these protons form hydrogen. However, the proton donor in our experiments was not water, but an acid,” Weigand says. “We observed that the proton of the acid is transferred to the phosphine oxide of our compound followed by a proton release to one of the iron atoms. A similar process would also be found in the natural variant of the molecule,” he adds. In order to balance the proton’s positive charge and ultimately produce hydrogen, negatively charged electrons were introduced in the form of electric current. With the help of cyclic voltammetry and simulation software developed at the University of Jena, the individual steps in which these protons were finally reduced to free hydrogen were examined. “During the experiment, we could actually see how the hydrogen gas rose from the solution in small bubbles,” notes Weigand.

    “The experimental measurement data from the cyclic voltammetry and the simulation results were then used by the research team in Milan for quantum chemical calculations,” adds Weigand. “This enabled us to propose a plausible mechanism for how the entire reaction proceeds chemically to produce the hydrogen – and this for each individual step of the reaction. This has never been done before with this level of accuracy.” The group published the results and the proposed reaction pathway in the renowned journal ACS Catalysis.

    The goal: hydrogen through solar energy

    Building on these findings, Weigand and his team now want to develop new compounds that can not only produce hydrogen in an energy-efficient way, but also use sustainable energy sources to do so. “The goal of the Transregio Collaborative Research Centre 234 ‘CataLight’, of which this research is a part, is the production of hydrogen by splitting water with the use of sunlight,” Weigand explains. “With the knowledge gained from our research, we are now working on designing and investigating new catalysts based on the hydrogenases, which are ultimately activated using light energy.”

    Een raakvlak met SunHydrogen (?)

    Soaking Up The Sun: Artificial Photosynthesis Promises A Clean, Sustainable Source Of Energy

    Humans can do lots of things plants can’t do: walk around, talk, hear and see and touch. But plants have one major advantage over humans. They can make energy directly from the sun.

    That process of turning sunlight directly into usable energy — called photosynthesis — may soon be a feat humans can mimic to harness the sun’s energy for clean, storable, efficient fuel. If so, it could open a whole new frontier of clean energy. Enough energy hits the Earth in the form of sunlight in one hour to meet human civilization’s energy needs for an entire year.

    Wind power and solar power, harnessed by photovoltaic cells, are the two major forms of clean energy available. Adding a third — synthetic photosynthesis — would dramatically change the renewable energy landscape. The ability to store the energy easily, without requiring bulky batteries, would dramatically improve the ability to power society cleanly and efficiently.

    Both wind turbines and photovoltaics have downsides in terms of environmental effects and complicating factors. But biophysicist Yulia Pushkar of Purdue University hopes artificial photosynthesis might be able to bypass those pitfalls.

    “We and other researchers around the world are working incredibly hard to try to come up with accessible energy,” Pushkar said. “Energy that is clean and sustainable we can create with nontoxic, easily available elements. Artificial photosynthesis is the way forward.”

    The closest process to artificial photosynthesis today is photovoltaic technology, where a solar cell converts the sun’s energy into electricity. That process is inefficient, capturing only about 20% of the sun’s energy. Photosynthesis, on the other hand, is much more efficient; it can store 60% of the sun’s energy as chemical energy.

    Now, U.S. National Science Foundation-funded scientists are mimicking the process by building an artificial leaf analog that collects light and splits water molecules to generate hydrogen. Hydrogen can be used as a fuel by itself via fuel cells or added to other fuels such as natural gas, or built into fuel cells to power everything from vehicles to houses to small electronic devices, laboratories and hospitals.

    The discovery, an insight into the way water molecules split during photosynthesis, was published in Chem Catalysis: Cell Press.

    Nanoparticle-Based Green Hydrogen Technology
    SANTA BARBARA, CA – July 19, 2021 – SunHydrogen, Inc. (OTC:HYSR), the developer of a breakthrough technology to produce renewable hydrogen using sunlight and water, today shared positive progress from its research team at the University of Iowa in the path toward scaling up its nanoparticle-based green hydrogen technology.

    Previously, the company announced its cooperation with Schmid Group in Freudenstadt, Germany, and InRedox in Longmont, Colorado. Alongside the University of Iowa research team, Schmid and InRedox are working to develop the company's nanoparticle technology to a commercial scale.

    Led by SunHydrogen Director of Technology Joun Lee and Lead Scientist Syed Mubeen, the University of Iowa research team is playing an integral role in developing chemistries for electroplating semiconductors that serve as the core component of SunHydrogen’s nanoparticle technology.

    Recently, the company in consultation with its manufacturing partners identified a surfactant, known as Triton X-100, in the chemistry that is banned in Europe for its toxicity. Triton X-100 was included in the chemistry to facilitate the electrochemical processes at the surface-liquid interface, resulting in the deposition of high-quality semiconductors.

    Today, SunHydrogen is happy to share that after testing several alternative surfactants, the University of Iowa team has successfully identified a biodegradable and environmentally benign substitute that can be added to the plating bath to grow semiconductors without compromising quality.

    The University of Iowa research team has also continued to improve the electrochemical process for depositing semiconductors. The current photoelectrochemical density achieved under laboratory conditions (without catalysts) could potentially result in a maximum solar-to-hydrogen efficiency slightly greater than 17%.

    "Our research team at the University of Iowa has made the chemistry for manufacturing our nanoparticle technology more environmentally benign without sacrificing the quality of the semiconductors. Our process is one step closer to being commercializable," said Tim Young, CEO of SunHydrogen, Inc.
