核心材料该如何助力绿氢成本逼近13元/kg？

Core Viewpoint - The article highlights the advancements and strategic positioning of Shanhai Hydrogen in the PEM electrolysis technology sector, emphasizing its innovative approaches to reduce costs and enhance efficiency in green hydrogen production [4][10]. Company Overview - Shanhai Hydrogen, established in March 2023 and headquartered in Shanghai, focuses on the research, production, and technical services of catalysts and membrane electrodes for PEM electrolysis [3]. - The company's vision is to become a global leader in PEM electrolysis technology, facilitating the low-cost large-scale application of green hydrogen and deep decarbonization in industries [3]. Technological Innovations - Shanhai Hydrogen has developed five core technological advantages: 1. Efficient Catalyst Technology: Utilizes an "embedded carrier" design, reducing iridium usage to 0.3 mg/cm², an 80%-85% reduction compared to commercial catalysts, achieving an electrolysis voltage of 1.72V at 3A/cm², with a theoretical lifespan exceeding 15 years [5]. 2. Advanced Slurry and Formulation Technology: Developed non-Nafion ionomer and composite slurry formulations, improving energy conversion efficiency by 10% while maintaining stability and adaptability [5]. 3. Innovative Coating Process and Equipment: Created a third-generation double-sided roll-to-roll direct coating technology, increasing slurry utilization from 50% to 95% and product yield from 80% to 95% [5]. 4. High-Safety Hydrogen Removal Technology: Developed ultra-thin two-dimensional hydrogen-blocking materials and optimized proton exchange membrane structures to enhance system safety [5]. 5. AI Design and High-Throughput Testing Platform: Collaborated with Caltech to develop AI-based catalyst screening algorithms, significantly accelerating research and development cycles [6]. Product Offerings - Shanhai Hydrogen offers two generations of standardized membrane electrode products, with the second generation demonstrating stable operation under a wide load fluctuation of 0%-400% for over 70 days and enduring more than 4000 start-stop cycles [8]. Application Scenarios - The company targets four main application areas: 1. Supporting green hydrogen replacement in high-carbon industries like steel and chemicals, aiming to bring green hydrogen costs close to 13 RMB/kg [9]. 2. Creating a hybrid alkaline + PEM hydrogen production system to optimize efficiency and cost [9]. 3. Serving large-scale hydrogen production from wind and solar energy, enabling full power range absorption of fluctuating renewable energy [9]. 4. Developing modular hydrogen production solutions for distributed energy and transportation, establishing a zero-carbon closed loop [9]. Future Development Plans - Shanhai Hydrogen plans to continue material innovation to reduce precious metal usage, expand production capacity to GW levels, and further lower green hydrogen production costs to below 11 RMB/kg [10]. - The company aims to support the anticipated global hydrogen demand of 150 million tons by 2030, positioning green hydrogen as a mainstream energy carrier [10]. Recognition - Shanhai Hydrogen received the "2025 Annual Technology Power Award" at the TrendBank Hydrogen Energy and Fuel Cell Industry Annual Conference for its groundbreaking PEM electrolysis technology [12].
