ENERCOAST aims at providing a state-of-the-art of the renewable energy sector (solar cooling systems, tidal/ current plants, heat pumps and wind turbines plants, little and medium sized). Such a result is achieved by means of a deep analysis of the available data and technologies for the exploitation of renewable energy sources (RES) in marine-coastal areas, aiming at identifying technical and non-technical solutions to increase the use of such technologies. Therefore, it aims at contributing to EU Blue Growth strategy through a transnational cooperation process in the Adriatic-Ionian sub-region Expected Results: • FINAL REPORT ON RES AVAILABILITY, THE EXISTING INSTALLATIONS, AND THE NATIONAL AND LOCAL LEGISLATION IN EACH COUNTRY Involved MED countries are endowed with a huge solar and wind energy potential which could bring various benefits to the MED region. Exploitation of sea energy (wave, tidal, heat pumps) for electricity and heat production is also one of the most promising sector but the use of e.g. heat pumps is still relatively modest. Providing incentives—subsidies, grants for their use—could help overcome these barriers. To increase the exploitation of renewable energy sources in marine coastal areas there is a need to adapt the policy framework that will provide an effective management and which will guarantee a sustainable development of MED area.• FINAL REPORT: 4 DETAILED ANALYSES OF TECHNOLOGIES UNDER INVESTIGATIONS Main technical and economic information for the analyzed technologies. Data for these technologies were collected from existing installations in Europe and the Mediterranean area, and listed in tables prepared for each technology followed with list of existing literature. Data from technology tables together with information on existing literature can be very good starting point in future case studies analyses.• STATE-OF-THE-ART STUDY OF THE RENEWABLE ENERGY SECTOR IN THE A-I COASTAL-MARINE AREAS State-of-the-art on the technical, economic, environmental, and legislative general framework of Renewable Energies development in the Adriatic Ionian Region. The main highlighted problems are high initial investments and lack of proper support by the States. At present, there are still many obstacles to overcome to achieve the promotion of renewable energy sources and their production to a higher level. The main problem is presented by national authorities who have to simplified procedures and authorizations for installation of various RES plants.• FINAL REPORT: PROPOSALS FOR FUTURE PROJECTS FOR THE EXPLOITATION OF RES 8 case studies on Renewable energy use in different locations in the Ionian: the technologies included seawater heat pump systems, solar cooling systems, vertical wind turbines, off-shore horizontal wind turbines and wave energy converters. The payback periods of the investments and the Net Present Values were not favorable except in simulations benefitting from public investment (state subsidy) either for the capital cost of the produced electricity or its feed-in tariff. However, due to the environmental benefits of these technologies (e.g. reduced greenhouse gas emissions) and the need to stop dependence on fossil fuels, public support of the most promising of them would increase their use and help overcome economic and technological (for tidal energy) barriers.
