the Swedish company SKF announced that its bearings and seals on one of the turbines had passed the 6 1/2-year mark without needing unplanned or disruptive maintenance.
I've read many optimistic articles detailing tidal energy projects, however they seldom address the inherent upkeep costs for equipment and infrastructure.
I'm glad maintenance is mentioned here, but I worry that it glosses over that only one out of the four turbines passed the six year mark without needing disruptive repair. How disruptive was the other turbine maintenance? Does it push it beyond viable profitability?
I genuinely do hope for the technology to mature and introduce more clean energy alternatives.
Haven't you heard the expression "Missed it by a mile."?
