Arrecife Energy Systems

‘Arrecife Energy Systems’ enterprise starts wave energy device tank trials

Publicada el junio 9, 2023junio 9, 2023 por BasqueScience

Basque Country-based marine energy start-up Arrecife Energy Systems has started testing the scale model of its wave energy device as part of the second phase of EuropeWave project.

Inspired by the behavior of coral reefs absorbing the energy of the breaking waves, Arrecife Energy’s device captures power from the movement of the ocean waves using cross-flow turbines located on the platform.

Following the competitive first phase of EuropeWave’s pre-commercial procurement (PCP) program, five wave energy projects have been selected to develop their concepts further in the next phase including Arrecife Energy’s Trimaran wave energy device.

The name comes from the device’s geometry, which is similar to a trimaran structure and incorporates multiple turbines and generators which are said to be able to provide constant and continuous energy delivery to the grid.

There, Arrecife Energy plans to carry out tests to seek improvements that would increase the efficiency of its device, with the focus on researching and increasing the shoaling effect.

Developed in partnership between Wave Energy Scotland (WES) and the Basque Energy Agency (EVE), the €20 million, five-year collaborative R&D funding program EuropeWave has been set up to procure the most promising wave energy technology solutions from developers across Europe and beyond.

In the third and final phase of the EuropeWave PCP, three prototype designs will be deployed at the open-water facilities of Biscay Marine Energy Platform (BiMEP) in the Basque Country and the European Marine Energy Centre (EMEC) in Scotland for a 12-month demonstration and operational testing program.

Arrecife Systems se inspira en el mar para crear energía limpia

“Hemos desarrollado un nuevo concepto para extraer energía de las olas del mar”, explica Iñigo Doria, CEO de Arrecife Energy Systems. La empresa se creó en 2016 y nace de la investigación llevada a cabo por José Javier Doria, catedrático de la Escuela de Ingeniería de Bilbao y experto en hidrodinámica.

El equipo ha patentado a nivel europeo la tecnología desarrollada, que supone una innovación en el ámbito de las energías renovables de origen marino.

El proyecto consiste en un sistema flotante similar a un catamarán, cuyo origen se inspira en el funcionamiento de los arrecifes de coral. El dispositivo está equipado con turbinas capaces de absorber el movimiento horizontal y vertical del oleaje, diseñado para aprovechar las olas pequeñas. Cuando hay temporales u olas de gran tamaño, el dispositivo se sumerge para no sufrir daños.

“Esto nos permite hacer un sistema más eficiente porque funcionamos con las olas más comunes, de 1 a 5 metros, que suponen el 98% del total”, explica Iñigo Doria.

Los sistemas que se utilizan actualmente consisten en boyas mucho más grandes y pesadas, diseñadas para resistir oleaje de gran altura: “Eso implica que solo producen energía con olas de más de 6 u 8 metros, lo que supone el 2%, y únicamente aprovechan el movimiento vertical”, destacó el CEO de la startup en esta entrevista.
