New Electrode Revolutionizes Hydrogen Production from Seawater (Source: Oil Price on 14 February 2024): University of Tsukuba researchers have developed highly durable electrodes without precious metals to enable direct hydrogen production from seawater. Water electrolysis utilizing renewable energy sources is emerging as a promising clean method for hydrogen production. But the water electrolysis method, a promising avenue for hydrogen production, relies on substantial freshwater consumption, thereby limiting the regions available with water resources required for water electrolysis. Therefore, it is imperative to develop a new technology for water electrolysis that can directly harness the abundant supply of seawater. The paper reporting the results has been published as “Durable high-entropy non-noble metal anodes for neutral seawater electrolysis” in the Chemical Engineering Journal. During seawater electrolysis, the anode reaction generates oxygen from water, chlorine gas, and hypochlorous acid from chloride ions. …
Nanosheet Breakthrough to Boost Sustainable Hydrogen Production (Source: Oil Price on 3 February 2024): City University of Hong Kong scientists have recently developed a novel strategy to engineer stable and efficient ultrathin nanosheet catalysts by forming Turing structures with multiple nanotwin crystals. This innovative discovery paves the way for enhanced catalyst performance for green hydrogen production. The report about the research has been published in Nature Communications. Hydrogen energy has emerged as a promising alternative to fossil fuels, offering a clean and sustainable energy source. However, the development of low-cost and efficient catalysts for hydrogen evolution reaction remains a crucial challenge. Producing hydrogen through the process of water electrolysis with net-zero carbon emissions is one of the clean hydrogen production processes. …
New Catalyst and Solar Process Produces Low Cost Hydrogen (Source: Oil Price on 14 December 2023): A study developed jointly by Istituto Italiano di Tecnologia (IIT) and the spin-off BeDimensional has identified a solution based on ruthenium particles and a solar-powered electrolytic system. Small ruthenium particles and a solar-powered system for water electrolysis can produce green hydrogen more efficiently and cheaply. The technology, developed in the context of the Joint-lab’s activities and recently published in two high-impact factor journals (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. IIT and BeDimensional’s researchers used nanoparticles of ruthenium, a noble metal that is similar to platinum in its chemical behavior but far cheaper, to serve as the active phase of the electrolyser’s cathode, leading to an increased efficiency of the overall electrolyzer. …
Scientists Invent Hydrogen Producing Solar Cell (Source: Oil Price on 26 January 2023): Ecole Polytechnique Fédérale de Lausanne chemical engineers have invented a solar-powered artificial leaf, built on a novel electrode which is transparent and porous. The artificial leaf is capable of harvesting water from the atmosphere for conversion into hydrogen fuel. The semiconductor-based technology is scalable and easy to prepare. The paper reporting the results has been published in Advanced Materials. A device that can harvest water from the air and provide hydrogen fuel – entirely powered by solar energy – has been a dream for researchers for decades. Now, EPFL chemical engineer Kevin Sivula and his team have made a significant step towards bringing this vision closer to reality. The team has developed an ingenious yet simple system that combines semiconductor-based technology with novel electrodes that have two key characteristics: they are porous, to maximize contact with water in the air; and transparent, to maximize sunlight exposure of the semiconductor coating. When the device is simply exposed to sunlight, it takes water from the air and produces hydrogen gas. …
Hydrogen Will Play A Key Role In The Gulf’s Energy Transition (Source: Oil Price on 26 September 2021): With hydrocarbon-rich countries in the Gulf increasingly looking to reduce their carbon emissions, some in the region are turning towards multi-coloured hydrogen as a more environmentally sustainable solution. Along with renewable sources like solar and wind, hydrogen is seen as a potential low-carbon or zero-carbon fuel that is key to the transition away from fossil fuels. However, it is important to note that there are different types of hydrogen with different impacts on the environment. For example, blue hydrogen is created when natural gas undergoes a steam reforming process. Although this process also produces CO2, the vast majority of it is captured and stored, subsequently producing a low-carbon fuel.
China Wants Huge New Green Hydrogen Plant Operational In 2023 (Source: Oil Price on 22 August 2021): China offers promise for clean energy in a world dominated by fossil fuel-driven hydrogen projects through its new green hydrogen mega-plant. China is planning a huge green hydrogen project using solar and wind power for its Inner Mongolia region. A cluster of plants will be constructed in the cities of Ordos and Baotou, expected to use 1.85 GW of solar power and 370 MW of wind power to produce approximately 66,900 tonnes of green hydrogen every year, according to the Hydrogen Energy Industry Promotion Association. If used for Fuel cell electric vehicles (FCEVs) it would replace the need for as much as 180 million gallons of gasoline a year, which would help China on its way to achieving its aim of 10,000 CVEVs and 74 hydrogen filling stations by 2025 in Beijing alone.
