Thyssenkrupp plans to hold a majority stake in its rebranded electrolysis unit after its initial public offering to tap into the growing market for green hydrogen to fight climate change. The engineering conglomerate is preparing to list its electrolysis plant business this year, renaming it Nucera, in a move that could value the unit at as much as €5-billion ($5.7-billion), people familiar with the matter said previously. Thyssenkrupp plans to hold more than 50% of shares following a rights issue by its joint venture with Italy’s Industrie De Nora.
