Hydrogen production is an important process for clean energy. One way to produce hydrogen is by electrolysis, where water is split into hydrogen and oxygen using an electric current. In this process, the surfaces of metal electrodes play a crucial role. Recent studies have highlighted how ion-specific water structures at these metal surfaces can significantly impact hydrogen production efficiency. Water molecules tend to arrange themselves differently when close to different ions. These arrangements, known as ion-specific water structures, can influence how easily hydrogen atoms are formed and released on metal surfaces. For instance, water molecules may form more stable structures…

The future of several energy projects in the province of Burgos hinges on the final route of hydrogen pipelines in the Iberian Peninsula. These pipelines need to link with local industrial centers, and the executive government must make the decision. So far, the hydrogen sector has promised investments worth over 620 million euros in the province. This commitment underscores Burgos’ significant role in developing the green hydrogen economy. However, this potential will be boosted or hindered based on Burgos’ inclusion in the final map of Spain’s Hydrogen Backbone Network. The coming autumn weeks will be critical in determining whether the…

Taiwan has shown a keen interest in expanding its hydrogen energy collaboration with Chile. The initiative is part of Taiwan’s broader strategy to diversify its energy sources and foster international partnerships in the renewable energy sector. This potential collaboration marks a significant step towards sustainable energy solutions for both nations. Hydrogen Energy’s Global Role Hydrogen energy is gaining global attention as a clean and renewable energy source. It can be produced from various resources, including natural gas, renewable electricity, and even water. Once produced, hydrogen can be used for electricity generation, vehicle fuel, and industrial processes. Its versatility and environmental…

Green hydrogen-derived methanol is gaining attention as a potential environmentally friendly fuel alternative for the shipping industry. This type of methanol is produced using green hydrogen, which is generated through electrolysis powered by renewable energy sources such as wind and solar. Its appeal lies in its significant potential to reduce carbon emissions compared to traditional fossil fuels. However, despite its environmental benefits, the cost remains a significant barrier to widespread adoption. Current Cost Issues The production of green hydrogen-derived methanol is currently expensive. The primary reasons are the high costs of generating green hydrogen and the subsequent synthesis process to…

The global hydrogen energy community has lost one of its most influential visionaries. Turhan Nejat Veziroğlu, a pioneer whose dedication to hydrogen as a clean energy source spanned decades, has passed away. His life’s work laid the foundation for hydrogen’s modern role in the energy transition, and his contributions continue to resonate in research, innovation, and policy. Veziroğlu, born in Turkey in 1924, was driven by a passion for science and sustainability from an early age. After earning his Ph.D. in mechanical engineering, he eventually turned his focus to the promise of hydrogen as an alternative energy source. It was…

The hydrogen production plant planned in Granja de Moreruela requires 116,910 cubic meters of water annually, equivalent to 35 Olympic swimming pools. The plant utilizes slightly more than half of this water, with the remainder rejected. This data is from documentation made public by the Department of Industry for the project’s administrative authorization, integrated environmental authorization, and environmental impact assessment. Water Source Assurance The water required for the plant will be sourced from existing captures and new well explorations to ensure a secure water supply. The project is located over the “Villafáfila” groundwater mass, which is in good overall condition…

Proton exchange membrane fuel cells (PEMFCs) are at the forefront of advanced energy conversion technologies due to their high efficiency, negligible emissions, and high specific energy. Yet, a persistent challenge has been optimizing performance under varying relative humidity conditions. A recent study published in the International Journal of Hydrogen Energy offers a promising solution. Three-Dimensional Interface Structure The researchers tackled this challenge by developing an asymmetric membrane coated with hydrophilic carbon nanotubes (HCNTs) on the cathode side of the proton exchange membrane (PEM). This innovative structure aimed to enhance the membrane’s dimensional stability by addressing water flooding-induced swelling on the…

Cement plants are notorious for their high carbon emissions. However, a Rio Grande do Norte factory is redefining this narrative by switching to green hydrogen as a key energy source. Green hydrogen, produced using renewable energy to split water into hydrogen and oxygen, presents an eco-friendly alternative to fossil fuels. Significance in Cement Industry The cement industry is one of the largest emitters of carbon dioxide. Green hydrogen can drastically reduce the carbon footprint of cement production. By using green hydrogen, the Rio Grande do Norte factory aims to minimize its environmental impact and set an example for other industries.…

The world’s first hydrogen-powered Light Rail Vehicle (LRV) line in China has been suspended. This project is recognized as the “first commercial hydrogen-powered tram in the world.” According to local media, the operator stopped services due to low passenger demand. The line, launched by Gaoming Modern Rail (GMR) in 2019, features a 6.5 km route and costs USD 118 million. It is located in Foshan, southern China, and connects the city center to Guangzhou South railway station, serving ten stops. CRRC Qingdao Sifang manufactured the trains, and Ballard supplied the hydrogen fuel cells. CRRC Qingdao Sifang holds a 20 percent…

EU member states are urged to introduce incentives to help the industry meet its ambitious 42% hydrogen goal by 2030. This call to action forms part of new guidelines, emphasizing hydrogen’s crucial role in achieving a sustainable future. These guidelines propose a variety of incentives and supportive measures to encourage industries to adopt hydrogen solutions more rapidly. Notably, the guidelines stress that achieving the 42% target will be challenging without significant government intervention and support. Among the recommended measures, financial incentives, tax reliefs, and grants are crucial tools that could drive investment in hydrogen technologies. Additionally, the guidelines call for…
