Elemed involved three EU member states -Cyprus, Greece and Slovenia- forming a strong consortium, comprised by a team of experts, from the marine, engineering and academic sector. Elemed prepared the ground for the introduction of cold ironing, electric bunkering and hybrid ships across the Eastern Mediterranean Sea corridor. Elemed aimed at studying all technical, regulatory, safety and financial issues related to the shore produced electricity and electric propulsion for vessels in Eastern Mediterranean region.

CYnergy provided a holistic approach towards the adoption of Natural Gas (NG) in Cyprus and the development of a sustainable and fully functional NG market for clean and affordable energy to the end user. The project, which was co-financed by the EU, was a collaboration of energy, transport and finance experts as well as private, public, and governmental institutions of Cyprus and Greece.

After a successful evaluation during the last few months actions ALFION and EALING started implementation thus expanding and strengthening the presence of Hydrus in the area of port electrification and energy upgrade.
