Design bidding for Longyuan Power’s wind-solar hydrogen production – green methanol – SAF project in Huanxian County, Gansu Province

Thread Content

On August 27, an open tender was issued for the basic design of the hydrogen production system, as well as the basic design of the utility and auxiliary facilities, and overall project management services, under the project titled \"Development and Application of Key Technologies for Biomass Gasification Coupled with Green Hydrogen Production to Create Green Fuels\" by Longyuan Power Longyuan (Huanxian) New Energy Co., Ltd. Xifeng Branch. Project overview: This project is located within the Xifeng Industrial Park (south area) in Qingyang City, Gansu Province, covering an area of approximately 60 mu. Adopting the technology route of \"new energy hydrogen production + biomass gasification + methanol synthesis + aviation fuel synthesis\", it is expected to produce 2,000 tons of green methanol and 60 tons of green fuel per year ； A 6MW distributed off-grid photovoltaic system is installed as part of this project; it has an annual utilization time of 1724 hours, resulting in an average annual power generation of 10.3443 million kWh. This system serves as a power source for water electrolysis to produce hydrogen. A 10-kilometer-long 35kV transmission line is also built to transport the electricity generated by these renewable sources to the chemical industrial park. The process outlined in this project enables full-scale technical verification of the entire chain: using green electricity generated from renewable sources for water electrolysis to produce green hydrogen, and then combining this hydrogen with syngas produced from biomass gasification to create green fuel products. Scope of the tender: The design scope for this tender includes, but is not limited to: 1. 1000 Nm³ electrolytic water hydrogen production system: mainly including rectifier transformers, rectifier units, alkaline electrolyzers, hydrogen and oxygen liquid separation devices, hydrogen and oxygen purification and drying systems, alkali solution circulation systems, alkali replenishment systems, pure water systems, cooling water systems, pipes and valves, as well as flexible control systems ； 2. Utility systems mainly include: power supply and distribution systems, water supply and drainage systems, natural gas systems, circulating water systems, fire protection water systems, initial rainwater tanks, steam boiler systems, plant air and instrument air systems, safety relief systems, sewage treatment systems, telecommunications systems, heating systems, pipeline valves, storage and transportation systems, as well as connections to external facilities ； 3. Auxiliary facilities: mainly include the control building, laboratory, warehouse, security office, roads, landscaping, etc ； 4. Detailed design of the entire plant’s system projects, including site leveling, fencing, main roads, main utility pipelines, etc.; bill of quantities, budgets; as well as HAZOP analyses and explosion-proof assessments for torches and similar elements. 5. Overall service management: Responsible for the unified coordination and management of biomass gasification, green methanol synthesis, green aviation fuel synthesis, hydrogen production via water electrolysis systems, as well as utility and auxiliary projects, with final oversight of the basic design. Preparation and review of all the above basic design documents (including review fees) ； Construction power supply design ； The entire design process, including equipment technical specifications, technical specifications in the tender documents, design drawings, technical regulations, boundary determination, quantity lists, and the preparation of maximum prices. It is reported that the total investment in this project amounts to 196.1 million yuan, and construction began on March 26, 2025, within the Xifeng Industrial Park in Qingyang, Gansu Province.
