I. Exhibition Scene: When PV Giants Collectively Reveal Their "Hydrogen" Cards As the world's largest PV exhibition, the exhibition halls of SNEC 2025 were somewhat different from previous years. Traditional solar cell and module companies occupied the prime positions, but the booths for energy storage systems (ESS), hydrogen energy, and smart chemical industrial parks were also bustling with activity. More notably, the four leading companies—LONGi, Trinasolar, Jinko, and GCL—also showcased their latest hydrogen energy equipment at their booths. Of course, there were also many gas companies and hydrogen energy enterprises presenting complementary offerings. Three Major Phenomena Addressing Industry Pain Points: Booth Structure Transformation : Trinasolar displayed electrolyzers alongside N-type TOPCon modules; LONGi's booth featured a full-process sand table of "green electricity → green hydrogen → green chemicals" at its core. Signings Data Insights : Among the 23 projects exceeding 100 MW signed during the exhibition, 17 included hydrogen production modules (compared to only 6 in 2024). Integration of Technological Routes : Huawei introduced the "Intelligent Hydrogen Production Energy Management System," achieving, for the first time, coordinated control of electrolyzers and PV inverters. II. In-Depth Analysis of the PV Winter: Why Hydrogen Energy is the Key to Breaking the Deadlock (I) Core Contradictions in the Industry's Predicament Hydrogen energy, however, provides a three-dimensional breakthrough point: Dimension Current Situation Limitations of Traditional Counterparts Capacity Utilisation Rate Global module capacity stands at 1.28 TW Shutting down production lines incurs significant losses Price System 182 bifacial modules priced at 0.78 yuan/W Cost inversion leaves no room for compression Consumption Bottleneck The curtailment rate of PV power generation in north-west China has rebounded to 5.3% The power grid expansion cycle is lengthy Capacity Conversion Valve: 1 GW of PV capacity can be paired with 200 MW of electrolyzers, with a conversion rate exceeding 1:5 (demonstrated at LONGi's Baotou base). Value Amplifier: PV electricity 0.3 yuan/kWh → green hydrogen 18 yuan/kg → synthetic ammonia 4,000 yuan/ mt , with a value-added rate exceeding 300%. Strong Policy Drivers: The EU's Carbon Border Adjustment Mechanism (CBAM) requires a 40% reduction in the carbon footprint of imported fertilizers, compelling the procurement of green ammonia. III.

After the exhibition concluded, an analyst from the International Energy Agency commented, "The Chinese PV contingent is creating a new paradigm: they are not just manufacturing components, but building cross-dimensional energy conversion hubs. Hydrogen energy has not only saved the PV industry but also reshaped the entire value chain of clean energy." In this industrial transformation, PV enterprises that were the first to embrace hydrogen energy are evolving from survivors of the PV winter into definers of a new energy era. When sunlight is converted into hydrogen energy to power 10,000-mt-class vessels, humanity truly embarks on the journey of transitioning from the "photovoltaic era" to the "hydrogen energy civilization."
