To make the energy transition, we need to mobilize as much natural energy as possible. Wind and solar power are already harnessing the wind and sun. What about water? Every day, trillions of tonnes of water are moved by ocean currents and river flows. Could this colossal force be used to generate electricity?
That’s what EEL ENERGY is trying to do. They have developed a tidal turbine that mimics the undulations of fish, adapting to the current to capture as much of its energy as possible.
This technology offers a number of advantages that set it apart from other attempts to harness the forces of nature. It: is predictable does not pose a risk to wildlife; is, for the same output, 10 times smaller; and does not cause noise or visual pollution.
Nevertheless, the project has not yet been scaled up. In early 2019, the price per MWH was estimated at €300, compared with €130 for wind power. However, they hope to bring the price down to €100/MWH with larger machines.
The Eel technology is covered by 5 international patents and works with leading partners such as IFREMER and Dassault Systems. It is the subject of considerable national exposure, having been the subject of articles in Les Echos, Le Parisien and many other national and regional titles.
