We have developed two test benches, which are unique in the world and allow the performance of tests that can be extrapolated to full scale and thus size the OTEC systems of tomorrow :
This commitment to performance is the result of continuous improvement efforts, notably carried out using the onshore ocean thermal energy prototype, installed since 2012 and used to conduct tests on the energy loop, validate system performance and qualify critical equipment. Both a research and development tool and a training platform for IUT students, this prototype allows the teams to work on the main electricity production system which could be used on the future plants. This installation serves to test new generations of equipment and continuously improve the efficiency of the energy system and the optimisation of technology costs.
Our experts are also developing innovative technological building blocks, such as biofouling prevention systems. A test bench was installed for this purpose in 2017 in Martinique, in partnership with IFREMER, as part of the Marlin project supported by the ADEME, then as part of the SIMBIOSE project supported by the EU. It is used to conduct tests on biofouling prevention systems and thus ensure the efficiency of the energy system’s thermal exchangers throughout the plant’s lifecycle.
Naval Energies is one of the signatories of the “industrial territories” protocol relating to the Bois Rouge eco-technoport on Réunion Island.
This project represents a major advance for OTEC projects that harness the potential of deep sea water.
LThe government’s “industrial territories” initiative, intended to promote the general reindustrialisation of French territories, is consistent with Reunion Island’s ambition for economic development. Thus, the combination of national challenges and regional strategies fosters numerous initiatives in favour of regional development, including the Bois Rouge “eco-technoport”.
This project comprises a first onshore component, based on the conversion of deep-sea water for multiple uses with, in particular the production of renewable electricity using the ocean thermal energy technology, sea water air conditioning (SWAC), industrial cooling, the supply of sea water for aquaculture, and desalination.
