Wave Energy Device Archimedes Waves Passes Test Successfully

The wave energy device Archimedes Waves has been a great success, beating test predictions by 20 percent. Archimedes Waves is recognized as one of the most extraordinary power plants in the world and its contribution to the renewable energy sector is under scrutiny after the successful test in Scotland. Scotland's AWS Energy has been conducting ocean-based tests at the European Marine Energy Center (EMEC) in Orkney for the last six months. The test trials have shown that it performs better than expected.

Waveswing consists of a cylindrical metal buoy attached to a single point on the ocean floor. As it works, it sits below the surface and responds to changes in water pressure. As the buoy moves up and down, it drives a hydraulic motor that converts linear motion into rotation. The device can be raised and lowered on its tether for maintenance and deployment. There is also a facility to regulate the air pressure inside the cylinder, effectively adjusting the air spring to take maximum advantage of wave conditions.

Archimedes Waves Could Change Prices in the Renewable Energy System

Archimedes Waves, which has made a name for itself among renewable energy devices, reportedly achieved an average power of 10 kW "during a period of moderate wave conditions" in the EMEC installation. The test also demonstrated that Archimedes Waves can survive Force-10 storm conditions. Given the size of Archimedes Waves, which is 7 m high and weighs 50 tons, the power seems surprisingly low. At the same time, it creates a very impressive image.

Thanks to Archimedes Waves, the efficient use of wave energy could radically reduce the price of renewable energy grids. In particular, such devices do not shut down at night or when the wind drops like solar power. This can reduce the need for long and short-term energy storage that a grid needs to guarantee a reliable supply of electricity. This, in turn, can reduce the upfront CAPEX (capital expenditure) of Wave Swell Energy's multi-mode renewable energy systems by two-thirds. However, it seems that it will be necessary to continue to be patient to get full results.
