Projects and outlook
Stiesdal Hydrogen ’ s technology is already deployed in real-world applications as the company has delivered three units of the HydroGen Electrolyzer for clean energy projects in Denmark .
The first project involves using the hydrogen produced from two Stiesdal Hydrogen units to upgrade raw biogas , which has a 40 % CO 2 content , to almost pure methane . This process not only improves the fuel production efficiency of biogas plants but also provides a sustainable use for the CO 2
, which would otherwise be emitted into the atmosphere .
The second project focuses on trailer filling , highlighting the electrolyzer ’ s ability to support hydrogen mobility applications .
“ We are gaining operating hours quickly , and our technology readiness level is increasing .”
Looking ahead , the company is in discussions with several project developers , particularly in Europe , to deploy its technology in large-scale projects . With a technology readiness level of 7 , Stiesdal Hydrogen is well on its way to commercializing its dynamic alkaline electrolyzer . “ We are gaining operating hours quickly , and our technology readiness level is increasing . The task now is to bring it to the wider market ,” concludes Nielsen .
