Against the backdrop of China's ongoing and deepening "dual carbon" strategy, hydrogen energy, leveraging its core advantage of zero-carbon cleanliness, has widely penetrated into diverse fields such as transportation, energy storage, industry, and cultural tourism, becoming a core driver of green energy transition. However, traditional hydrogen storage methods have long had obvious shortcomings: high-pressure gaseous hydrogen storage is prone to safety hazards such as leakage and deflagration, while cryogenic liquid hydrogen storage suffers from high energy consumption and costs, making it difficult to meet the current industry demands for safer, more efficient, and more accessible development. The industry urgently needs entirely new hydrogen energy storage and supply solutions. Addressing this industry pain point, Jiayi Huaqing Technology Co., Ltd. has launched the 7.2kg Solid-State Hydrogen Storage System, which, built on mature metal hydride adsorption-based hydrogen storage technology, reconstructs the safety ecosystem of hydrogen energy storage and transportation, providing robust technical support for the large-scale deployment of hydrogen energy across multiple scenarios.
It is reported that this new solid-state hydrogen storage system adopts an integrated architecture, consolidating six core components to achieve intelligent, precise, and safe management across the entire process of hydrogen storage and supply, building a solid foundation for stable system operation from the equipment detail level. The device is equipped with an intelligent LCD touchscreen that displays real-time core operational data including pressure, temperature, and operating status. It also features a built-in hydrogen concentration audible and visual alarm device that provides instant warnings when parameters become abnormal, mitigating safety risks at the source. Additionally, dual pressure gauges are configured for independent management of inlet and outlet gas conditions: the inlet side can precisely regulate pressure to 2-5MPa, while the outlet side can deliver stable hydrogen output in the 0.01-0.5MPa range, precisely matching the operational requirements of different hydrogen-consuming equipment. Both ends adopt NPT1/4 standard connectors, ensuring both compatibility and safety.
In terms of equipment compatibility and temperature control assurance, the system is equipped with customized inlet and outlet gas connectors that can be flexibly adjusted in specifications according to downstream equipment, seamlessly interfacing with various terminal devices such as hydrogen-powered electric motorcycles, drones, vessels, and energy storage cabinets. A 25mm-diameter ferrule-type circulating water inlet is provided, equipped with a built-in temperature sensor for real-time monitoring of inlet water temperature. Through the water circulation system, precise heating and cooling regulation of hydrogen storage materials is achieved, ensuring the equipment consistently operates under optimal conditions. The integrated cylinder valve incorporates pressure-reducing valve functionality, automatically adapting to the pressure standards of various hydrogen-consuming equipment. Combined with a dual design of quick connectors and rebar threads, it significantly simplifies equipment installation and subsequent maintenance procedures.
Driven by foundational technological innovation, this system has developed four core performance advantages, comprehensively leading the solid-state hydrogen storage segment. In terms of safety, the device relies on a low-pressure solid-state hydrogen storage mode combined with metal hydride hydrogen-locking technology, fundamentally eliminating the leakage and deflagration hazards of high-pressure hydrogen storage. Coupled with multiple intelligent monitoring and early warning systems and having passed rigorous testing under various harsh operating conditions, its safety performance far exceeds that of traditional hydrogen storage equipment. In terms of operational stability, independent monitoring via dual inlet and outlet gauges and automatic pressure stabilization through the built-in pressure-reducing valve ensure smooth and fluctuation-free hydrogen output, meeting the stable hydrogen supply requirements of various equipment and effectively enhancing system operational efficiency.
Intelligence and environmental adaptability: the device achieves full operational data visualization and management through the LCD touchscreen, with round-the-clock intelligent monitoring and surveillance, rapid response to abnormal conditions, and fully intelligent safety operations and maintenance throughout the entire process. It also features an ultra-wide operating temperature range of -15°C to 60°C, capable of handling complex conditions such as extreme cold, intense heat, and high altitudes with ease, enabling stable deployment across different regions and various scenarios nationwide, with exceptionally strong environmental adaptability.
Leveraging its safe, reliable, efficient, and stable product characteristics, this 7.2kg solid-state hydrogen storage system can broadly empower zero-carbon transformation across multiple fields, with rich and diverse application scenarios. In the transportation sector, it can be paired with hydrogen-powered electric motorcycles, drones, patrol boats, industrial forklifts, and logistics hydrogen vehicles to achieve safe energy replenishment and extended driving range. In the energy sector, it can be combined with PV hydrogen energy storage cabinets to facilitate green electricity storage, absorption, and efficient utilization, promoting the deployment of distributed new energy systems. In industrial and park scenarios, it can meet the demands for stable hydrogen supply in factories and zero-carbon smart park energy supporting needs, facilitating low-carbon industrial upgrades. In the cultural tourism and commercial sector, it can be adapted for clean energy supply in green scenic areas and zero-carbon commercial districts, creating benchmark low-carbon demonstration applications.
The successful launch of Jiayi Huaqing's 7.2kg solid-state hydrogen storage system represents a significant breakthrough by the enterprise in the core technology domain of hydrogen energy storage and supply, effectively addressing the industry pain points of insufficient safety, poor economics, and weak compatibility in hydrogen energy storage and transportation. The commercialization and promotion of this product will accelerate the commercialization and large-scale popularization of hydrogen energy technology, continuously improve the application ecosystem across the entire industry chain of hydrogen energy, and provide solid technological and equipment support for achieving China's "dual carbon" goals and green, low-carbon energy transition.
