The main objective of the TRIĒRĒS project is the creation of a “Small Scale Hydrogen Valley”, with geographical reference to the Motor Oil Refinery of Ag. Theodoroi in Corinth. By linking the green hydrogen production unit that the MOH is developing there within the EPHYRA project, with businesses, technology providers, academic and research institutions, public sector organisations and local government bodies, a hydrogen economy will be established in Greece. The TRIĒRĒS Valley aims to demonstrate the combination and integration of multiple hydrogen applications (city buses, passenger vehicles, shipping, power plants, etc.) into an efficient and resilient interconnected ecosystem that covers the full hydrogen value chain of production, storage, transport, and distribution of green hydrogen to end user applications.
