The Ocean Thermal Energy Conversion (OTEC) prototype, designed to withstand severe tropical storms, has reached the 50% completion milestone at Hidramar Shipyard in Gran Canaria. This project, managed by the PLOTEC consortium and funded by the EU, aims to advance renewable energy solutions for Small Island Developing States (SIDS) vulnerable to severe weather. The cylindrical hull will be assembled and tested in the Atlantic Ocean, with insights expected to enhance OTEC’s viability and contribute to marine engineering advancements.
