KK Wind Solutions has entered into a framework agreement with Stiesdal Hydrogen to supply power supply units and cooling solutions for a new modular green hydrogen plant concept aimed at cutting costs across the sector, the companies said on Wednesday.
The Danish firm, based in Ikast, will provide Power Supply Units (PSUs) and Electrolyser Control Systems customised to site-specific needs. These systems are designed to manage fluctuating inputs from renewable sources and ensure stable and efficient hydrogen production through electrolysis.
“By combining the PSU and Electrolyser 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 hydrogen sector,” said Michael Ariel Nielsen, vice president of business development at KK Wind Solutions.
The partnership supports Stiesdal Hydrogen’s modular, turnkey hydrogen plant model, which aims to reduce capital expenditure with costs projected to fall below €1000 per kilowatt. The new framework agreement builds on an existing collaboration between the two companies that began in 2021.
Under the agreement, KK Wind Solutions will supply systems for future projects based on standardised 3.1MW electrolyser modules. These can be scaled from 12.4MW configurations to significantly larger capacities, depending on site requirements.
Cooling systems from Nissens Cooling Solutions, acquired by KK Wind Solutions earlier this year, will be integrated into the offering to improve performance, safety and efficiency under demanding operational conditions.
The two companies previously achieved a milestone in 2023, producing the first kilogram of green hydrogen at a pilot facility in Denmark. The latest agreement aims to support further commercial deployment of electrolysis technology across Europe.
“This framework agreement demonstrates how our combined expertise enables stable and efficient hydrogen production, supporting the transition to a sustainable energy future,” Nielsen added.
The companies stated that integrating advanced power electronics with next-generation thermal management is a key step toward making large-scale, renewable-based hydrogen production more cost-competitive.
