Ocean-based renewable energy, such as tidal energy, is increasingly being seen as Ireland’s best alternative renewable energy source, overtaking the more common wind energy. Now, a new string has been added to its bow, as Limerick is set to become home to the first OC1 device in Ireland. Having undergone trials since late October, with previous testing taking place at the IFREMAR testing centre in Boulogne-Sur-Mer, France, the OC1 has officially launched at the Shannon Foynes Port Company (SFPC). Designed by GKinetic’s founder, Vincent McCormack, the OC1 device works by exploiting the natural phenomena that occurs when water accelerates around an obstacle, which accelerates the flow of water to eight-times that which would occur naturally, creating greater amounts of energy. “This particular device is a river unit, but our plan is to create large scale tidal units capable of generating up to 1 MW.
