KK Wind Solutions, a power, control, and cooling solutions for renewables company, will deliver key technologies for a green H₂ plant concept being developed by Stiesdal, a Danish clean-tech pioneer.

The company has already delivered several power supply units (PSU) and electrolyzer control systems to Stiesdal Hydrogen, and framework agreements are in place to supply similar modules for future turnkey H₂ plant concepts.

Projects typically start at around 12.4 MW, based on standardized 3.1-MW electrolyzer modules, and can be expanded stepwise to larger capacities, enabling flexible scaling of green H₂ production.

The electrolyzer control system will be tailored to Stiesdal Hydrogen’s exact site specifications, ensuring stable and efficient operation of the electrolysis process by managing dynamic renewable inputs and delivering reliable power to the electrolyzer stacks. This will result in the electrolyzer producing green H₂ at maximum efficiency while reducing operating costs. Stiesdal Hydrogen’s new plant concept targets capital expenditure (CAPEX) below EUR 1,000 per kilowatt, a significant reduction compared to current market prices.

The agreement also benefits from state-of-the-art thermal management technologies from Nissens Cooling Solutions — now part of KK Wind Solutions. Together, these integrated systems secure optimal performance, efficiency, and safety under highly demanding operational conditions.

“By combining the PSU and electrolyzer control system and harvesting the synergies from the cooling technologies acquired through Nissens Cooling Solutions, we are uniquely positioned to provide comprehensive power electronic and thermal management solutions for the green H₂ sector,” said Michael Ariel Nielsen, VP of Business Development at KK Wind Solutions.

“This framework agreement demonstrates how our combined expertise enables stable and efficient H₂ production, supporting the transition to a sustainable energy future. Thank you to Stiesdal Hydrogen for your continued partnership and innovation in driving forward this important industry.”
