Shanxi Meijin Hydrogen’s project for producing 20,000 tons of industrially high-purity hydrogen per year has been completed and put into operation
Thread Content
Recently, the Meijin Hydrogen project, with an annual production capacity of 20,000 tons of industrially high-purity hydrogen, was completed and put into operation in the Fine Chemicals Recycling Industrial Park located in Qingxu Economic Development Zone, thereby providing a new driving force for the high-quality development of this zone. The reporter learned that this project makes use of the coking gas produced by the 3.85 million tons per year coking unit of Meijin Huasheng Chemical New Materials Co., Ltd. located within the park (approximately 350–450 m3 of coking gas is generated per ton of coke, with hydrogen accounting for 54%-59% of this gas). In addition to being used for the deep processing of chemicals such as 300,000 tons per year of ethylene glycol and 150,000 tons per year of LNG, the remaining gas is subjected to negative pressure adsorption to isolate high-purity hydrogen at a purity of 99.999%. The total investment in the project is approximately 100 million yuan, with construction carried out in two phases. Phase 1 has a production capacity of 2,000 Nm3/h; the associated hydrogenation station with a capacity of 500 kg/day began construction in February of this year and has now been put into operation. It produces 1,570 tons of high-purity hydrogen per year, enough to supply 400 buses, 570 freight vehicles, or 170 heavy trucks. The second-phase project plans to add equipment on top of the main unit from the first phase, in order to increase production capacity to 20,000 Nm3/h. Expand production capacity through compressor-driven filling and pipeline delivery ； At full capacity, the project will produce 15,700 tons of high-purity hydrogen, sufficient to meet the needs of 5,500 buses, 8,000 delivery vehicles, or 2,200 heavy trucks when operating at full load. At this production level, the hydrogen liquefaction facility can still be expanded to increase the hydrogen transportation capacity, enabling supply to neighboring provinces. At the same time, in collaboration with industry partners, efforts have been initiated to plan and build 24 hydrogen refueling stations or oil-hydrogen hybrid stations in 10 districts of Taiyuan City.
The Shanxi Meijin Hydrogen Energy Industrial Park project originated on September 27, 2019, with the signing of a Project Investment Agreement with the Jinzhong Development Zone in Shanxi Province. The project began with its groundbreaking ceremony on October 29, 2019; after nearly a year of construction, by October 10, the final assembly workshop for the complete vehicles was ready for operation. It is reported that the project has a total planned area of 3,500 mu, and once fully operational, it will be able to produce 50,000 hydrogen fuel cell power systems and 50,000 hydrogen fuel commercial vehicles per year ； Phase 1 of the project covers an area of 1,200 mu, with production targets of 10,000 hydrogen fuel cell power systems per year, 500,000 KW of hydrogen fuel cell stacks, and components for 10,000 hydrogen fuel commercial vehicles. The project involves the construction of production facilities such as manufacturing workshops, auxiliary workshops, warehouses and transportation buildings, as well as public power systems, in addition to supporting facilities for offices, research and development, and living purposes.
Is hydrogen stored in this type of gas cylinder? How much hydrogen can a gas cylinder hold?
I’m not sure; it’s made by fiberglass winding, and large-scale versions probably aren’t expensive
