Jeju Island is developing as a significant site for industrial hydrogen production in Korea. KraftPowercon will supply a 5 MW rectifier system for HyAxiom's electrolyzer project, which is essential for converting AC from the medium-voltage grid to stable DC for electrolysis.

The H2Kraft solution features a standardized container design for easier installation and commissioning. The rectifier system is designed to reduce harmonic current and maintain grid stability as hydrogen production scales. The project, awarded in December 2025, emphasizes the need for reliable power infrastructure to support industrial hydrogen production.
