Lithium battery companies can assist the hydrogen energy industry in increasing efficiency through four major pathways

Today, China’s hydrogen energy industry is at a critical juncture, shifting from pilot exploration to a large-scale breakthrough, and from policy-driven to market-driven development. It faces real challenges such as high costs of core components, insufficient system compatibility, an insufficiently mature control and management framework, and limited expansion of application scenarios.

The author believes that lithium battery enterprises can build on mature technological accumulation, full industrial-chain capabilities, and market-oriented operating experience, to orderly export and deeply empower common technologies, general-purpose materials, management systems, and mature products into the hydrogen energy field, and to help the hydrogen energy industry speed up and improve efficiency through the “four major pathways.” For lithium battery enterprises, deeply empowering the hydrogen energy industry not only releases market demand, but also helps upgrade technologies and products, thereby building differentiated, distinctive, and systematic competitive advantages.

First, strengthen system integration and coordination, and drive the leap of hydrogen energy power from steady-state energy supply to efficient adaptation across all scenarios.

Hydrogen fuel cells have high energy density and long endurance, but their dynamic response is slow, their low-load efficiency is not high, and frequent variable-load operations lead to wear and tear, making it difficult to meet requirements under complex operating conditions such as transportation and energy storage. Lithium battery enterprises, having accumulated deep know-how in multi-energy coupling, power distribution, energy recovery, and thermal management, can directly empower hydrogen energy systems with mature hybrid architectures and integration capabilities, thereby building an integrated “fuel cell + lithium battery” power and energy storage solution. By optimizing energy management strategies, fuel cells can operate stably in efficient operating ranges, while lithium batteries take on functions such as peak power delivery, rapid response, and start-stop buffering—achieving efficient coordination of hydrogen as the main power source and lithium batteries for peak shaving and energy supplementation. This not only improves the reliability, durability, and economy of hydrogen energy systems, but also significantly expands application scenarios, accelerating large-scale deployment of hydrogen in fields such as commercial vehicles, rail transit, ships, and distributed energy storage.

Second, promote the reuse of materials and processes, helping key hydrogen energy components achieve large-scale cost reduction faster.

High costs of core materials and key components are important factors constraining the large-scale development of hydrogen energy. There is a high degree of commonality between lithium batteries and hydrogen energy in terms of material systems, fabrication processes, and electrode structures. The technological spillover and production capacity synergy of lithium battery enterprises can effectively address cost-related challenges in the hydrogen energy industry. Enterprises can apply technologies such as development of transition metal materials, surface modification, and structural control to the development of fuel cell catalysts and electrode materials for electrolyzing water to produce hydrogen, thereby reducing dependence on precious metals. They can use experience in designing and manufacturing high-stability separators and electrolyte solutions to enable improvements in fuel cell membrane-electrode performance and to support domestic substitution. They can also transfer mature manufacturing processes such as coating, roll pressing, film forming, and packaging to mass production of fuel cell stacks and core components, improving consistency, yield, and production efficiency—driving low-cost, large-scale, and standardized supply of key hydrogen energy components.

Third, accelerate the spillover of management technologies to upgrade hydrogen energy systems from extensive operation to refined control.

The large-scale development of hydrogen energy depends on a safe, efficient, and intelligent control and management system. After long-term market validation, the lithium battery industry has formed comprehensive management capabilities across the entire chain, including state monitoring, health assessment, thermal management, fault early warning, and safety protection. Lithium battery enterprises can transfer and optimize core algorithms, control logic, and engineering experience from the Battery Management System (BMS) to the Fuel Cell Management System (FCMS), enabling real-time monitoring and intelligent adjustment of stack status, hydrogen operation, temperature and pressure, and energy efficiency—thereby improving system safety and operational efficiency. At the same time, by copying intelligent manufacturing, quality control, and full-lifecycle management systems into the hydrogen equipment manufacturing sector, the industry can promote unified standards, standardized processes, and controllable quality, laying a solid management foundation for large-scale and commercial operation of hydrogen energy.

Fourth, deepen cross-domain technology integration to expand hydrogen energy applications from single power generation to multi-scenario, diversified breakthroughs.

To make the hydrogen energy industry bigger and stronger, it is necessary to continuously broaden the boundaries of applications and innovate technical routes. Lithium battery enterprises can leverage their R&D advantages in electrochemical systems, interface regulation, structural design, and cell integration, and actively participate in cutting-edge R&D such as lithium–hydrogen batteries, hydrogen anion batteries, and solid-state hydrogen energy storage. They can promote deep integration of lithium battery technology with hydrogen chemical systems to create new energy storage devices with high energy density, high safety, and rechargeable charge–discharge cycling capabilities. This not only breaks through performance limitations of traditional fuel cells and lithium batteries, but also helps hydrogen energy move from the “power generation end” to the “energy storage end,” forming an integrated pattern of power generation + energy storage + end-use applications. This opens up broader market space for distributed energy, grid peak shaving, backup power, and special equipment, providing long-term growth momentum for the hydrogen energy industry.

The maturity and strength of China’s lithium battery industry are a unique advantage for industrializing hydrogen energy technologies. In the future, as system integration becomes more efficient and materials reuse goes deeper, the hydrogen energy industry is expected to rapidly break through cost and scenario bottlenecks, enter a new stage of large-scale development as soon as possible, and thereby form a new energy-industry landscape characterized by dual engines driving and supporting each other—lithium batteries and hydrogen energy—along with coordinated upgrades.
