Hellenic Hydrogen A.E. (HH) is a Greek company founded in January 2023 as a joint venture between Motor Oil Hellas (51%) and Public Power Corporation (PPC, 49%). It specializes in the development and implementation of renewable hydrogen production projects using electrolysis powered by renewable energy sources.
The company focuses on large-scale facilities to support Greece's energy transition, targeting hard-to-abate industries, e-fuels, and mobility sectors. Its flagship North-1 project, located at a decommissioned lignite site in Amyntaio, Western Macedonia, features an initial 50 MW electrolyzer capacity, expandable to over 150 MW.
In May 2026, Hellenic Hydrogen secured funding from the European Commission's third Hydrogen Bank auction for its AN-1-B phase—a 25 MW electrolyzer—with the lowest bid of €0.57/kg for 38,654 tons of renewable hydrogen over 10 years. The project contributes to decarbonization efforts in the region.
