NEMOS WEC
NEMOS is an innovative system for generating electricity from ocean waves. The incoming energy is absorbed by an elongated floating body and transmitted to a generator shaft by a belt system. Performing its motion on a curved trajectory and being controlled by the directly coupled generator, the floaters hydro-mechanical efficiency is way above standard technology. The system can be adjusted to changing environmental conditions so that energy output is maximized and loads are limited. To protect the system in heavy storms, the floater can be lowered to calmer waters. At full-scale the NEMOS WEC will have a floater of 40 m by 8 m and a 16 m long substructure and will produce about 1 MW of clean ocean energy. In 2019 a scaled prototype of the NEMOS WEC was built and tested; it featured an 8 m x 2 m floater and a 16 m long substructure.
