LONGi Hydrogen revealed two new innovations, LONGi HyBlock and LONGi HySmart, at World Hydrogen Week 2025. Together, they cover equipment, modular system design, and intelligent operation and maintenance (O&M). The pair reflects the company’s approach to accelerating large-scale green hydrogen deployment.
As the industry expands, developers are contending with rising pressure on both CAPEX and OPEX. Developers are grappling with high equipment costs, complex integration, and rising energy expenses.
HyBlock streamlines delivery and reduces CAPEX, and at the same time, HySmart uses digital intelligence to manage operational costs effectively. Together, the two solutions make hydrogen production more competitive and more sustainable.
LONGi HyBlock is built for hundred-megawatt to gigawatt-scale projects. Instead of traditional indoor setups, HyBlock uses value-engineering principles. Electrolyzer systems run reliably outdoors, and integration is moved from the site to the factory. This cuts down on on-site work, shortens timelines, and makes managing projects easier.
With standardization and prefabrication, HyBlock can reduce CAPEX by up to 35% and trim lead times by 40%. Installation is roughly 65% faster, with fewer interfaces and improved parallel efficiency. Designed to operate in any climate, from high-temperature areas to humid coastal regions, it enables scalable hydrogen production across the globe. In partnership with Morimatsu, HyBlock also benefits from high-standard modular manufacturing and smooth delivery.
LONGi HySmart uses AI to streamline O&M and tackle the increasing operational complexity of green hydrogen projects. It combines real-time monitoring, diagnostics, intelligent control, and predictive optimization. Digital twins and smart algorithms help maximize both energy efficiency and hydrogen output.
The platform monitors more than 30 safety indicators, cuts inspection time by roughly 80%, and can predict equipment failures up to 72 hours in advance with over 98% accuracy. With AI-assisted diagnostics and expert support, faults can be resolved quickly, keeping unplanned downtime to a minimum. Smart energy management can also reduce DC power use by about 1.2%, directly lowering OPEX and the Levelized Cost of Hydrogen (LCOH). Whether in new projects or retrofits, HySmart improves safety, efficiency, and long-term bankability.

“The introduction of HyBlock and HySmart reflects our insight into the industry’s core challenges. Achieving scale in hydrogen production requires addressing both CAPEX and OPEX constraints. The real breakthrough lies not only in electrolyzer performance, but in rethinking how projects are conceived, constructed, and operated — through modularization, standardization, and digital intelligence. These innovations demonstrate LONGi Hydrogen’s commitment to driving greater efficiency, intelligence, and commercial viability across the green hydrogen value chain.”
