The SETS II project facilitates a faster conversion to sustainable electrical operations in the ports of the Kattegat-Skagerrak Region. It aims at ensuring a green and flexible energy supply in port areas and a reduction in CO2 and particle emissions. The regional ports will be models, which can further contribute to the promotion of a full-scale sustainable transport system in the cross-border region. SETS II promotes cross-border and cross-sector cooperation in the region regarding new methods, approaches, and solutions related to port electrification. Cooperation has been conducted across university environments, public actors, business promotion organizations, local authorities, utilities, advisors and private companies. The project supports ports in preparing electrification plans with an accompanying strategy for implementation. It focuses on electrification and potential battery operation in maritime areas as well as technical service, business models, and financing models.
