H24wave
The company’s H-type wave and tidal energy converters, always completely submerged, consist of a guiding part located on the sea floor, or on a support structure, and of a moving part above it, which moves according to waves or tides. The H24 model is a wave energy converter (WEC) for near-shore, shallow water applications (between 5 and 12 meters of depth). The H-type devices is different from most other WECs in design in that it sits fully submerged in the water. The H24 consists of a moving member - called Upper Member (UM) - running on a horizontal path under the action of sea waves. An electro-mechanical transmission system (TEP), controlled by a program running on a programmable logic controller (PLC), is able to control the UM motion, and convert a certain percentage of its kinetic energy in electric power. The machines have a very high capacity factor, and are resilient to storms and passively protected against large waves. The footprint of a 25kW H24 device is 9m x 14m and they weigh 15 tonnes, including mooring. The device is transportable by a conventional HGV, and can be towed into situ without the need for any specialist equipment. Each H24 unit requires 6m of coast and 80m² surface area.
