The HYDEA project in the Atlantic area is making significant strides towards the deployment and utilization of green hydrogen-based technologies in ports. Launched in November 2023, this three-year initiative, backed by a budget of €3.43 million from the Interreg Atlantic Area 2021-2027 program, is led by the EnergyLab Technology Center. The project consortium, comprising partners from Spain, France, Ireland, and Portugal, is dedicated to accelerating the integration of green hydrogen technologies with marine and renewable energies in Atlantic area ports. The partners of the HYDEA project have recently unveiled the 'first concrete results', introducing an interactive map that highlights key hydrogen initiatives in ports such as Brest, Leixões, Vigo, and Seville. This map not only identifies promising hydrogen applications but also outlines existing bottlenecks and opportunities in these port locations. The project's initial phases have focused on evaluating potential green hydrogen technologies based on various critical factors like cost, energy efficiency, and decarbonization impacts. Subsequently, the project has delved into analyzing technical, economic, social, and regulatory obstacles to implementing hydrogen-based infrastructures in the identified port regions. Furthermore, a detailed study has been conducted to pinpoint opportunities for fostering the hydrogen economy within the ports of Brest, Leixões, Vigo, and Seville, taking into account their connection to hydrogen value chains. The consortium of the HYDEA project includes key stakeholders such as port authorities from Vigo, Seville, Brest, and Douro, technology centers, universities, and companies like Hive Hydrogen, Automotive Synergy Evolution, and Energy Observer Developments. Together, these entities aim to drive innovation, promote sustainable practices, and advance the hydrogen economy in the Atlantic area ports.
