This energy transition of all Spanish ports will require an investment of more than 4.5 billion euros, according to a report published by Ocean Capital Partners (OCP) in 2023. These funds would go towards the implementation of renewable energy sources, the electrification of port facilities and the production of biofuels such as methanol, ethanol or hydrogen for ships. The challenges posed by this process were addressed at the meeting "Electrification as a key to the decarbonization of the maritime business", organized by EXPANSIÓN with the collaboration of Finanzauto.
