Project Overview
Against the backdrop of the UK's active promotion of low-carbon transition and operational automation in the transportation sector, a technologically advanced unmanned LNG refueling station has been successfully deployed and commissioned. Utilizing a 45-foot standard container as the integrated carrier, it houses a 20 cubic meter vacuum-insulated storage tank, a submersible pump skid, a dual-nozzle dispenser, and a fully automated control system. The station enables the entire process—from vehicle identification, safety verification, and refueling settlement to data upload—to operate intelligently without on-site personnel. It provides a 24/7 available clean energy refueling point for the UK's long-haul freight, municipal fleets, and industrial users. Furthermore, with its highly compact design and low operational costs, it presents an innovative infrastructure solution for promoting LNG fuel in markets with high labor costs.

Core Product & Technical Features

1. Highly Integrated Containerized Design
   All station equipment is integrated within a 45-foot weatherproof container, employing a multi-level space-optimized layout. The upper level accommodates the storage tank and main process piping, while the lower level integrates the pump skid, control cabinets, and safety equipment. This design significantly reduces the footprint and offers relocation flexibility, making it suitable for rapid deployment in areas with limited land resources or for temporary needs.
2. Safety systems are comprehensively upgraded for the unmanned scenario:
   • Active Monitoring: Integrates flame detection, cryogenic leak sensors, combustible gas concentration monitoring, and video analytics cameras.
   • Automatic Protection: Features a redundant Emergency Shutdown System (ESD) that can联动 in real-time with the refueling process and monitoring signals.
   • Remote Supervision: All safety data and video streams are uploaded in real-time to a cloud-based monitoring center, enabling remote inspection and emergency command.
3. Energy Efficiency Optimization & Low-Maintenance Design
   • Storage Tank: Utilizes high-vacuum multilayer insulation with a daily evaporation rate below 0.3%.
   • Pump Skid: Employs a Variable Frequency Drive (VFD) submersible pump that adjusts output based on demand, reducing energy consumption.
   • Control System: Incorporates equipment health prediction and energy efficiency analysis functions, supporting preventive maintenance to minimize on-site service frequency.

Project Value & Industry Significance
The successful application of this unmanned LNG refueling station not only meets the UK market's demand for automated, low-carbon, and highly reliable energy infrastructure but also, through its highly integrated containerized solution, provides a leading example for promoting small-scale, modular, and intelligent LNG refueling facilities across Europe and globally. It demonstrates that in environments with strict regulations and high operational costs, technological innovation can achieve efficient, safe, and economical operation of clean energy infrastructure, powerfully advancing the intelligent transformation of the transportation energy system.
