The hydrogen generation market is readily evolving, hosting both traditional industrial giants and specialized electrolyzer manufacturers who are constantly vying for leadership. Key players in this field are expanding production capacities and forming strategic partnerships and acquisitions to scale green hydrogen deployment and meet heightened global demand. In this regard, Thyssenkrupp Nucera in September 2025 reported that it had completed the acquisition of key technology assets from Green Hydrogen Systems (GHS), which included intellectual property and a full-size test facility in Skive, Denmark. This acquisition strengthens thyssenkrupp nucera’s expertise in alkaline water electrolysis, now including pressurized solutions capable of producing hydrogen at up to 35 bars, which is ideal for industrial applications. In addition, this strategic move enhances the company’s innovation and global leadership in green hydrogen technology, supporting its development roadmap.
