“穿”上“氢”装再出发

Core Insights - The city of Daye is transitioning from a historical mining hub to a green energy center, focusing on hydrogen energy as a key component of its economic transformation [1][2]. Hydrogen Production and Infrastructure - The Jiangqiao hydrogen production plant has a design capacity of 3,200 standard cubic meters per hour, with an annual output of 1,500 tons of green hydrogen, sufficient to meet the hydrogen needs of 200 buses or 100 mining vehicles [2]. - The plant employs a dual process of alkaline electrolysis and PEM (Proton Exchange Membrane) electrolysis, reducing energy consumption by 15% and achieving zero alkaline liquid discharge and zero wastewater pollution [2][4]. - A new photovoltaic power station, built on a repurposed abandoned mine, has a total installed capacity of 20 megawatts, expected to generate 20 million kilowatt-hours annually, significantly lowering electricity costs for the hydrogen production facility [3]. Hydrogen Storage Innovations - The first underground hydrogen storage project in China is being developed in Daye, utilizing a cylindrical cavern capable of withstanding pressures of 10 MPa, which is three times the capacity of conventional high-pressure tanks [5]. - This project aims to address the challenges of hydrogen storage, particularly the issue of "hydrogen embrittlement," by using a newly developed high-strength hydrogen-resistant metal composite material [5][6]. Policy Support and Industry Development - Daye has introduced 16 supportive measures for the hydrogen industry, covering the entire hydrogen value chain from production to storage and usage, including financial incentives for companies producing over 500 tons of green hydrogen annually [8]. - The city plans to deploy 300 hydrogen vehicles by June next year, with current operations including 12 hydrogen buses and various commercial vehicles, consuming approximately 16 tons of green hydrogen monthly [7][8]. - The establishment of a hydrogen innovation technology park aims to attract upstream and downstream enterprises in the hydrogen industry, facilitating a comprehensive hydrogen management platform for efficient energy use and carbon reduction [8].
