Proven expertise in grid compliance
Grid compliance remains a critical success factor for green hydrogen plants.
Leveraging decades of experience from the wind sector, KK Group plays a key role in ensuring plants meet stringent grid requirements. Our PSUs build on technologies such as smart inverters and advanced control systems — adapted from wind turbines to hydrogen applications — while our integrated cooling systems maintain optimal performance under varying grid and operational conditions.
By embedding grid compliance and thermal stability early in the project lifecycle, we help developers reduce risk, avoid costly redesigns, and accelerate deployment.
A global supply chain you can rely on
The competitiveness of green hydrogen depends on efficient, large-scale manufacturing and secure component supply.
As the largest converter manufacturer in the wind industry — and now a full-line supplier of both power and cooling solutions — KK Group leverages its global footprint, scale and technology to drive down cost and complexity.
Our resilient global supply chain combines advanced power and cooling technologies with worldwide reach, enabling us to deliver reliable, end-to-end solutions for electrolysers that meet the dynamic demands of the green hydrogen market.
