May 6, 2025 – Munich, Germany – At the prestigious The smarter E AWARD ceremony, LONGi Hydrogen’s 3000 Nm³/h ALK G Series electrolyzer, implemented in the project of hydrogen-enriched blast furnace, was honored with the Outstanding Projects Award 2025, becoming the only hydrogen-related winner of the year. This international recognition underscores LONGi Hydrogen’s continuous innovation and growing influence in the global green hydrogen sector.
The ALK G Series is currently in stable operation at the 450m³ hydrogen-enriched blast furnace demonstration project in China, validating its industrial applicability and decarbonization potential.
Commercial-scale deployment demonstrates feasibility
The 3000 Nm³/h ALK G Series electrolyzer is the largest single-unit alkaline electrolyzer currently in commercial operation worldwide. Its deployment demonstrates the scalability and engineering viability of large-scale green hydrogen systems.
Performance gains drive economic efficiency
With energy consumption as low as 4.2kWh/Nm³, a 20% reduction in system footprint, and 10% lower capital expenditure, the G Series sets new standards in cost-efficiency—further accelerating the reduction of Levelized Cost of Hydrogen (LCOH).
Industrial integration enables real-world decarbonization
The system’s integration into the hydrogen-enriched blast furnace pilot has enabled an 8–11% reduction in CO₂ emissions during the ironmaking process. It demonstrates the viability of green hydrogen as a decarbonization pathway for hard-to-abate sectors such as steel.
The award jury commented:
“Our judges praised the ground-breaking project for demonstrating how hard-to-abate industries can transition to green energy.”
At LONGi Hydrogen, we remain committed to customer-oriented innovation and cross-industry collaboration. By leveraging our proven project experience and strong system integration capabilities, we are contributing to a sustainable future powered by green hydrogen.
