BAKU: The world’s largest green hydrogen plant, which is under construction in Saudi Arabia, is on-track to begin production in December 2026, the company’s CEO told Arab News. NEOM Green Hydrogen Company is now 60 percent complete, according to CEO Wesam Al-Ghamdi. Al-Ghamdi emphasized the ambition of the project, which he described as “being built at a scale no one has attempted before.” The plant will rely entirely on solar and wind energy to power a 2.2 gigawatt electrolyzer, designed to produce hydrogen continuously, he said.
