French hydrogen player HDF Energy, German engineering company Neuman & Esser (NEA), and German International Cooperation Society (GIZ) have signed a letter of intent (LoI) to jointly explore green hydrogen applications for decarbonizing maritime transport across Indonesia’s small islands.
NEA and HDF Energy, supported by GIZ under the International Hydrogen Ramp-Up Program (H2Uppp ), will reportedly lead a feasibility study examining hybrid hydrogen and battery-powered ferry systems, with the goal of delivering a technical and financial blueprint for clean, reliable, and scalable interisland transport.
