Generating NH3 marine fuel through floating renewable energy

The BAHÍA H2 OFFSHORE project, which will be located in the public domain of the Santander Port Authority, focuses on the development of an innovative solution, which proposes the production of renewable hydrogen and its conversion to green ammonia from offshore renewable energies; all this on a barge where production is carried out in situ and what is transported to land is the green ammonia generated, combining all the processes in the same space and optimising the occupation of the marine space as much as possible, as well as greater ease of maintenance.
