- The study validates the use of supercapacitors and semi-solid state batteries to reduce emissions during port operations.
Valencia, March 11, 2026. Last January saw the completion of the European AENEAS project, an initiative that benefited from the strategic participation of the Fundación Valenciaport and analyzed the potential of various advanced energy storage technologies to improve energy efficiency and reduce emissions in maritime transport.
The project focused on analyzing how supercapacitors and semi-solid state batteries can transform the efficiency of ships. These technologies have been evaluated in critical high-energy demand scenarios, such as docking maneuvers and stays in port, proving to be a key solution for minimizing the environmental impact of maritime transport.
Impact and replicability
Within the consortium, Fundación Valenciaport has evaluated the environmental and economic impact, which has made it possible to quantify the potential for reducing fuel consumption and CO₂ emissions that these innovations bring to the sector.
In addition, the Foundation has developed a pioneering replicability study, analyzing the feasibility of integrating these systems into various segments of the current fleet. The conclusions highlight that these solutions are particularly cost-effective and efficient in newly built ships and in operations that require high power peaks over short periods.
About the AENEAS Project
Funded by the Horizon Europe program, AENEAS had a budget of €4.89 million and the collaboration of 14 leading European partners. During its 36 months of implementation, the project has laid the foundations for real, large-scale electrification of maritime and river transport, aligning the industry with global sustainability goals.
