European Energy orders electrolyzer from Stiesdal

Mar 27, 2023

The first electrolyzer for European Energy’s hydrogen production facility in Maade, Esbjerg, is going to be supplied by Stiesdal – a Danish climate technology company.

European Energy and Stiesdal subsidiary Stiesdal Hydrogen have entered into an agreement on testing a new  3 MW electrolyzer developed by  Stiesdal Hydrogen. The electrolyzer will be installed at European Energy’s hydrogen facility in Maade, Esbjerg.

Stiesdal Hydrogen’s electrolyzer is based on conventional alkaline electrolysis with a novel, integrated design. The support systems (water treatment, power supply and cooling) are fully modularized, and the complete system is well suited for low-cost industrial manufacturing.

European Energy is responsible for designing and delivering the complete balance of plant as well as constructing the Maade facility which will have a total capacity of 12MW. The electrolyzer supplied by Stiesdal Hydrogen will be able to produce roughly 270 tons of hydrogen a year when fully operational.

– With its innovative take on proven alkaline electrolysis, we find that Stiesdal Hydrogen is one of the most promising electrolyzer manufacturers today. At European Energy we believe that their industrial approach and attractive cost level is a perfect fit for our un-subsidized hydrogen production at Maade, says Emil Vikjær-Andresen, EVP and Head of Power-to-X at European Energy.

Construction started late  2022 on the Maade PtX-facility and the facility will begin operation in 2023.

– We are honored to be working with European Energy on this pioneering project. European Energy’s commitment to clean energy aligns perfectly with our mission at Stiesdal, and we look forward to producing sustainable hydrogen at Maade with the first generation of our HydroGen Electrolyzer, says Peder Nickelsen, CEO at Stiesdal Hydrogen.

Stiesdal is a Danish climate technology company, developing and commercializing technologies that have major impact on mitigating climate change. Stiesdal has activities in floating offshore wind, energy storage, Power-to-X hydrogen production and carbon capture and storage combined with green fuel production.
