Denmark’s Hyped Green Hydrogen Company Plunges After Design Flaw

A Danish company producing electrolysers that create green hydrogen from renewable energy fell the most since its initial public offering after announcing that a design flaw would lead to further delivery delays. 

Green Hydrogen Systems A/S fell as much as 28% in Copenhagen trading on Tuesday, the most since the June IPO, and has now lost about half its market value since the listing.
