LONGi Hydrogen unveiled two major innovations at World Hydrogen Week 2025 in Copenhagen, Denmark, on October 8, 2025. The company launched LONGi HyBlock and LONGi HySmart, representing an end-to-end innovation across equipment, modular system design, and intelligent operation and maintenance for advancing large-scale green hydrogen deployment.

Company Performance and Market Presence

Since its establishment in 2021, LONGi Hydrogen has achieved over 500 MW of cumulative global orders, with footprints spanning 10 countries and regions. The company has progressed from pilot demonstrations to commercial-scale projects, gaining insights into the evolving challenges of the green hydrogen industry. As the sector moves toward large-scale applications, developers face dual pressures on both CAPEX and OPEX, including high equipment investment, complex system integration, and rising energy and maintenance costs.

LONGi HyBlock Modular Solution

LONGi HyBlock is an outdoor modular solution designed for hundred-megawatt to gigawatt-scale green hydrogen facilities. The system represents a departure from traditional indoor configurations by applying value-engineering principles. This enables electrolyzer systems to perform reliably under diverse outdoor conditions while shifting complex system integration from the construction site to the factory.

By combining standardization and prefabrication, HyBlock can deliver up to 35% savings in CAPEX and 40% shorter overall lead time, while significantly reducing uncertainty from decision-making to commissioning. Installation work can be reduced by approximately 65%, with fewer interfaces and higher parallel efficiency. The system is engineered for all-climate deployment, ensuring reliable operation in environments ranging from high-temperature areas to humid coastal regions.

LONGi Hydrogen has partnered with Morimatsu, a leader in large-scale modular design and manufacturing, to enable high-standard module production and efficient delivery for the HyBlock system. Ms. Marisol Wu, Business Development Manager of LONGi Hydrogen, presented HyBlock at the event, while Mr. Federico Gustavo, Pre-Sales Manager of LONGi Hydrogen, also presented the system. Mr. Jiahua Wang, Sales Manager of Morimatsu, presented the modular design and manufacturing capabilities.

LONGi HySmart Intelligent Platform

LONGi HySmart is an intelligent operation and maintenance platform purpose-built for hydrogen production facilities. The platform addresses the growing operational complexity of green hydrogen deployment, where system reliability has become a decisive factor for project success. HySmart integrates real-time monitoring, diagnostic analytics, intelligent control, and AI-assisted optimization through digital twins and intelligent algorithms.

The platform tracks more than 30 key safety indicators and reduces inspection time by about 80%. It predicts potential equipment failures up to 72 hours in advance with over 98% accuracy. With AI-assisted diagnostics and expert-mode support, HySmart enables rapid fault identification and closed-loop issue resolution, minimizing unplanned downtime. The intelligent energy management feature can reduce DC power consumption by around 1.2% under typical operating conditions, directly lowering OPEX and LCOH.

The platform can be integrated into new projects or retrofitted to existing assets to enhance operational safety, efficiency, and long-term bankability. Mr. Hyacinthe Flandrin, Pre-Sales Manager of LONGi Hydrogen, presented HySmart at the event.

Company Leadership Statements

Zhang Haimeng, Vice President and Chief Strategy & ESG Officer of LONGi Green Energy, stated that the introduction of HyBlock and HySmart reflects the company's insight into the industry's core challenges. He emphasized that achieving scale in hydrogen production requires addressing both CAPEX and OPEX constraints. The real breakthrough lies not only in electrolyzer performance but also in rethinking how projects are conceived, constructed, and operated through modularization, standardization, and digital intelligence.

Mr. Wei Zhou, General Manager International of LONGi Hydrogen, also delivered a speech at the event. The company positions these innovations as demonstrating LONGi Hydrogen's commitment to driving greater efficiency, intelligence, and commercial viability across the green hydrogen value chain. LONGi Hydrogen operates as a subsidiary of LONGi Green Energy, founded in March 2021.

The company promotes the “Green Power + Green Hydrogen” approach and is dedicated to becoming a global leading company in large-scale water electrolysis solutions. LONGi Green Energy was founded in 2000, and SH operates as an international company with business in more than 160 countries and regions, focusing on customer-driven value creation for comprehensive energy transformation scenarios.
