Experimental and numerical investigations on renewable energies at CNR-INSEAN: Challenges and future perspectives

The exploitation of renewable energies from the oceans requires an interdisciplinary approach to solve all the problems linked to a hostile environment and to the need to limit the frequency of operations and maintenance processes. The development of renewable energies from the sea relies not only on classical mechanical, electrical, electronics, control and systems engineering but also on material engineering and on hydrodynamics and fluid structure interaction science. CNR-INSEAN contributes to the latter two

The development of renewable energies from the sea relies not only on classical mechanical, electrical, electronics, control and systems engineering but also on material engineering and on hydrodynamics and fluid structure interaction science. CNR-INSEAN, the Marine Technology Research Institute at the Italian Research Centre, has an almost centenary experience in these latter two fields and is now active in sustainable exploitation of the marine environment, providing its support to overcome the challenges posed by these new technologies.

The main marine renewable energy sources are offshore wind, tides, ocean currents and waves. The estimated power of the oceans is 2 million TWh/y but only a very small part of it is harvested at the moment. To enlarge the quantity of energy that can be actually extracted, it is necessary to overcome some of the technological challenges that each one of the different resources implies.

The research work at CNR-INSEAN supports technology developers with the most advanced expertise and capabilities in model testing and computational modelling of device hydrodynamics. …
