All components for the HydroGen Electrolyzer are delivered to the site on two standard trucks : one truck ( above ) for the main pressure vessel , and one truck for the power and auxiliary modules .
production lines and benefit from the economies of scale that these established companies offer . It also provides the flexibility needed to navigate challenging market conditions , such as project delays and supplychain disruptions . “ By working with established partners , we can rapidly scale up production , which is crucial for meeting the growing demand for green hydrogen ,” Nielsen adds .
Adapting the electrolyzer design to industrial manufacturing
When designing the electrolyzer , the Stiesdal Hydrogen team focused on the optimal use of materials and minimizing waste .
An example of this approach is the design of the electrode stack , which is rectangular instead of round and housed in a pressure vessel . The unique rectangular design , resembling a plate heat exchanger , minimizes material waste , reducing production costs and improving overall efficiency . “ By designing a rectangular stack , we cut material waste
to under 5 %, compared to over 20 % with a round stack ,” Nielsen explains . “ This not only reduces material waste but also significantly lowers production costs , making the electrolyzer more economically viable .”
“ By designing a rectangular stack , we cut material waste to under 5 %, significantly lowering production costs .”
A round stack design typically leads to substantial material wastage because the plates used in the stack are cut from large metal sheets , and the leftover material cannot be reused efficiently . The rectangular design , on the other hand , maximizes the use of raw materials and streamlines the manufacturing process . “ By minimizing waste , we not only cut costs but also contribute to more sustainable production practices , aligning with our overall mission to support a greener future ,” says Nielsen .
