在四川，太阳还能“晒”出氢能源

Core Viewpoint - The article discusses the launch of the world's first commercial project for hydrogen production through solar energy, located in Panzhihua, China, utilizing a unique technology that integrates multiple facets of strontium titanate for efficient hydrogen generation [5][10]. Group 1: Project Overview - The Panzhihua multi-faceted strontium titanate solar hydrogen production pilot base is the first of its kind globally [6][10]. - The project employs "multi-faceted strontium titanate concentrated quantum hydrogen production technology," achieving water splitting for hydrogen generation [7][10]. - The facility features 144 polygonal heliostats that reflect sunlight to a central reaction tower, where hydrogen and oxygen are produced [6][9]. Group 2: Technological Innovation - The core catalyst used in the project is multi-faceted strontium titanate, which has 26 faces, enhancing its ability to convert solar photons into electrons [8][10]. - The hydrogen produced has a purity of 99.8%, while the oxygen purity reaches 98.6% [9]. - The project has demonstrated a cost-effective hydrogen production method, with costs around 21 yuan per kilogram, significantly lower than traditional electrolysis methods [10][12]. Group 3: Economic Impact - The first phase of the project occupies 33 acres and is expected to produce approximately 200 tons of hydrogen annually, generating an estimated annual output value of 7 million yuan [13]. - The project aims to develop a large-scale hydrogen production base, with a target of producing 12,000 tons of green hydrogen within three years [13][14]. - The anticipated reduction in hydrogen production costs to 16 yuan per kilogram upon full operation will further enhance the project's economic viability [13]. Group 4: Environmental Benefits - The project is expected to reduce carbon dioxide emissions by 48,000 tons annually once fully operational [13]. - Hydrogen produced through this method is considered green hydrogen, as it is generated without carbon emissions, utilizing renewable energy sources [14]. - The technology allows for hydrogen production in various environments, including high-altitude, desert, and marine areas, solely relying on sunlight [14].
