Green hydrogen production

Green hydrogen systems rely on electrolyzers that require stable, isolated DC power to operate efficiently and safely. Any voltage or current fluctuation can damage stacks or reduce hydrogen output. KraftPowercon’s DCKraft™ converter delivers fault-free, isolated DC conversion, ensuring steady power flow between renewable sources and electrolyzer stacks — a foundation for consistent, high-yield hydrogen production.

The DCKraft™ system enables a direct, single-step connection between renewable DC sources (solar, wind, battery systems) and the electrolyzer’s DC bus. By eliminating unnecessary AC conversion stages, it reduces system complexity and energy losses, offering a more efficient and cost-effective power link for hydrogen plants.

DCKraft™ supports all major electrolyzer technologies, including: - PEM (Proton Exchange Membrane) - Alkaline - SOEC (Solid Oxide Electrolyzer Cells) Its flexible voltage and current control allow precise tuning to each technology’s unique load profile, ensuring optimal process performance and stack lifetime.

With stable, isolated DC conversion, DCKraft™ prevents grid disturbances from affecting the hydrogen process. It ensures uninterrupted operation even under fluctuating renewable input, improving uptime and lowering OPEX. The high-efficiency design and low-loss topology translate into more hydrogen produced per kWh consumed.

Yes. Each DCKraft™ converter is designed to be modular and scalable up to 10 MW, allowing hydrogen plants to expand capacity easily as demand grows. This modular approach supports multi-stack electrolyzer systems and clustered installations, simplifying project phasing and investment planning.

Hydrogen environments demand high electrical safety and isolation standards. DCKraft™ integrates galvanic isolation and fault protection, shielding both the grid and electrolyzer stacks from electrical disturbances. Built with industrial-grade components and tested for continuous duty, it ensures maximum reliability and compliance with international safety norms.
