📌 K-INN Tech and Hydrogen: A Path to Excellence in Clean Energy Production. Our commitment at K-INN Tech is twofold: to pursue an ambitious goal, and to utilize hydrogen as a means to generate valuable products sustainably. 👉 The main objective is to study and optimize hydrogen production methods. We conduct in-depth experimental campaigns on various chemical reactions, such as natural gas and alcohol reforming, hydrocarbons cracking, and partial oxidations of heavy hydrocarbons. This allows us to optimize the operational conditions of the reactor and to test new catalyst formulations. 👉 We also face an even more challenging task: increasing the purity of hydrogen. The importance of this parameter is recognized in relation to the various applications of hydrogen. Our expertise in selective oxidation reactions enables us to identify the optimal conditions to preferentially consume unwanted compounds, such as CO, over hydrogen, ensuring maximum purity. 👉 Finally, hydrogen acts as a crucial reaction vector in our patented process for producing biomethane from biogas.

"What does it take to produce green hydrogen more efficiently and cheaply? Apparently, small ruthenium particles and a solar-powered system for water electrolysis. This is the solution proposed by a joint team involving the Istituto Italiano di Tecnologia (Italian Institute of Technology, IIT) of Genoa, and BeDimensional S.p.A. (an IIT spin-off). The technology, developed in the context of the Joint-lab's activities and recently published in Nature Communications and the Journal of the American Chemical Society, is based on a new family of electrocatalysts that could reduce the costs of green hydrogen production on an industrial scale." #hydrogen #greenhydrogen

🌟 Excited to share our latest research on industrial-scale green hydrogen production published in Nano Energy! A significant issue with academic research on heterostructure electrocatalysts is that it often focuses on their excellent electrocatalytic activity, with limited testing under more realistic conditions. Our team has addressed this by developing a directly grown bimetallic phosphide/oxide heterostructure electrocatalyst and testing it under simulated industrial conditions. This catalyst requires only 1.76 V for 1 A cm-2 via an alkaline water electrolyzer (AWE), significantly outperforming the conventional Raney Ni electrocatalyst, which requires 2.5 V for 0.5 A cm-2. The most interesting part is our accelerated degradation test, demonstrating superior robustness for intermittent energy sources. Our findings align perfectly with the targets set by the DOE and FCH-JU. Proud to contribute to the advancement of sustainable energy technologies! 🌱🔋 #GreenEnergy #HydrogenProduction #SustainableTech #ResearchInnovation #CleanEnergy #Electrolyzer #SKKU #NanoEnergy

Harnessing Solar Energy for Sustainable Hydrogen Production In the quest for sustainable energy solutions, researchers are making significant strides in artificial photosynthesis, a process that mimics nature's ability to convert sunlight into energy-rich molecules. One promising approach involves splitting water into hydrogen and oxygen using sunlight and a photocatalyst. In this innovative process, a photocatalyst in sheet form, soaked in water, is exposed to sunlight. The catalyst efficiently separates water molecules into hydrogen and oxygen, all without the need for electricity. A key advantage of this method is its carbon-neutral nature; no CO₂ emissions are generated during production, as solar energy drives the reaction. Central to the success of artificial photosynthesis is the energy conversion efficiency rate. Researchers aim to achieve a rate of 4% by 2024 and 10% by 2030. To accomplish this goal, they are developing photocatalytic sheets that can be produced in large sizes, enabling cost reductions. Outdoor testing at expansive sites, spanning tens of thousands of square meters, will validate efficiency rates. The project's photocatalyst is garnering attention as a transformative technology poised to revolutionize the energy landscape. As advancements continue, artificial photosynthesis holds the promise of sustainable hydrogen production, paving the way for a cleaner, greener future #ArtificialPhotosynthesis #SolarEnergy #HydrogenProduction #Sustainability #RenewableEnergy

Heterostructure electrocatalysts have emerged as promising candidates for efficient water splitting due to their unique structural advantages. These electrocatalysts combine different materials at the nanoscale, resulting in synergetic effects that enhance catalytic activity and stability. By understanding the structural advantages, we can unlock the full potential of heterostructure electrocatalysts for renewable energy production. Heterostructure electrocatalysts offer several key components that contribute to their superior performance. One important aspect is the ability to create controlled interfaces between different materials. These interfaces facilitate optimized electron and ion transport, enabling efficient charge transfer within the catalyst. Additionally, the interfaces provide a platform for improved reactant adsorption, maximizing the utilization of active sites and enhancing catalytic activity. Another advantage of heterostructure electrocatalysts lies in their unique composition. By combining different materials, researchers can tailor the catalyst's properties to meet specific requirements. For example, the addition of a foreign element through doping can modify the electronic structure and improve catalytic performance. This compositional flexibility allows for fine-tuning the catalyst's properties for water-splitting applications. Furthermore, the nanoscale nature of heterostructure electrocatalysts enhances their stability. The small size of the catalyst particles reduces the diffusion path length for reactants and products, minimizing energy losses. Additionally, the controlled interfaces between different materials prevent particle agglomeration and preserve the catalyst's structural integrity over extended periods of operation. In summary, the structural advantages of heterostructure electrocatalysts, including controlled interfaces, tailored composition, and enhanced stability, make them highly promising for water-splitting applications. By harnessing these advantages, researchers can develop efficient and cost-effective technologies for renewable energy production.
