On July 2, 2025, Greece made significant progress in its energy transition by passing Law 5251/2025, the country's inaugural hydrogen legislation. This law focuses on creating a structured approach to the production, certification, and regulation of renewable hydrogen, aligning with EU directives and strategies. By introducing rules for various types of hydrogen and emphasizing green hydrogen production, the law sets the stage for Greece to boost its sustainability efforts in line with the European Green Deal and other energy frameworks. The streamlined licensing process, highlighted by the Hydrogen Producer Certificate, aims to simplify procedures and position hydrogen as a vital player in Greece's energy landscape. This move not only accelerates the country's transition to renewable sources but also positions Greece as a potential regional leader in hydrogen exports, leveraging its strategic location and renewable energy resources.
