A tidal turbine submerged off the Scottish coast has achieved a significant milestone, operating continuously for more than six years to harness the power of ocean tides for electricity. This remarkable durability, with the unit spinning approximately 40 metres (44 yards) below the surface, underscores the technology's commercial viability.
According to the trade association Ocean Energy Europe, maintaining a large, grid-scale turbine in such a harsh marine environment for this duration is a record. This longevity is crucial, as it helps pave the way for the development of larger tidal energy farms and significantly enhances the sector's appeal to investors. The proven resilience of the technology mitigates the prohibitive costs that would arise if turbines required frequent removal for maintenance.
