The European Union’s Green Deal wants to make Europe the first climate-neutral continent by 2050. In order to achieve this goal, the energy transition is one the main challenges. For that reason, there are increasing efforts to make port greener, backed by EU project financing, particularly to develop a hydrogen-based energy production and to electrify the quays and provide green energy to docked ships. The EU recently presented its Hydrogen Plan with three phases, until 2050, supported by the new European Clean Hydrogen Alliance. Under this continental framework, the RH2INE project has received funding to research the transportation based on hydrogen-powered inland barges, connecting the port of Rotterdam with Rhine region. Further on, three new projects will impulse the electrification of quays in the ports of Valencia, Helsinki and Venice. These projects are both in a study and application phases, being the cruises and ferries as the first ones to benefit from on shore power supply.
