PYTHEAS Technology onboard the first energy-producing dike in France
Since 2020, PYTHEAS Technology participates in the development of Dikwe, a “positive energy” coastal dike. Let’s review the advances of this project, which allows us to, once again, take part in the energy transition.
Producing energy while protecting coasts and ports
Led by Groupe Legendre, Geps Techno and Ifremer, the Dikwe project aims at equipping a seawall with a wave motor system, composed of an oscillating flap activated by waves. It converts wave energy into sustainable and local electricity. Here is where PYTHEAS Technology has a role. We have developed the PTO (Power Take Off), which converts mechanical energy generated from waves into electricity. Our solution offers high efficiency on a large range of swell and tide conditions, even in extreme sea conditions.
A promising system under test
After a first test phase on a 1/15th scale prototype in Ifremer’s wave tank in Brest in 2020, the prototype’s design and the first numerical analysis were approved.
This second test phase on the roadstead of Brest uses a 1/4th scale prototype, a 4.5 m high and wide and 6 m deep container. It uses sensors to measure waves, electricity production and structure resistance.
A third test phase on a full-size prototype (almost 20 m high and wide) able to produce about one megawatt, will be necessary to validate Dikwe’s feasibility and industrial relevance. The prototype should be built in 2023 and launched in 2024.
We expect these tests to be promising for the future of Dikwe as it is a chance for PYTHEAS Technology to install new devices at sea.
