Projects & Track Record
Advent Technologies has successfully completed over 38 EU- and nationally sponsored projects in Greece, securing more than €12 million in funding to advance the development of fuel cell materials and components. Notably, the Green HiPo IPCEI project, based in Kozani, aims to manufacture HT-PEM fuel cells and electrolyzers, backed by a €60 million budget that includes a €24 million grant from Greece's Just Transition Fund. This initiative is crucial for the region's transition from coal to green energy and aligns with Europe's ambitious renewable hydrogen targets.
