SWEDISH WAVE POWER CAN SUPPLY


THE WORLD WITH CLEAN ENERGY Imagine a clean energy source, inspired by the human heart, with the potential to generate 10-20 percent of all electricity needed globally


Corpower Ocean is determined to create wave power that can handle tough storms and tight budgets. Armatec has supplied vital components for this, until now, secret project.


A STRANGE PHONE CALL In late 2013 a man called Fredrik Johansson at Armatec and asked many questions about pressure relief. To get involved with the mysterious project Fredrik had to sign a document of confidentiality. Fredrik commented “The technical challenges were out of the ordinary which was the thrill of it for me.”


EXTREME ENVIRONMENT The ocean’s energy supply is endless but nobody has been able to develop wave power robust enough to withstand its power while delivering energy at a reasonable price –


Corpower is changing that. Patrik Möller, CEO of Corpower Ocean explained: “We have developed highly efficient wave power converters inspired by the human heart – behind the technology is cardiologist Stig Lundberg. A buoy with an air spring inside generates energy, similar to the heart muscle’s movement when pumping blood.


“The buoy extracts five times more energy than traditional wave power plants for a third of the cost, which makes the technology highly relevant.”


ELEVATED TECHNOLOGY The buoys of 20 metres will be in constant use for 20 years which makes maintenance difficult and complicated. That’s why each product in the redundant system is selected with great care.


Armatec supply the ball and safety valves. When a wave sweeps in, a giant air spring in the buoy is pressed and then retracted. If pressure gets too high, the safety valves have to be trusted to let the right amount of air out.


Patrik concluded “Armatec are technically experienced and understand our high demands, who have the knowledge to suggest the best solution which is a perfect match for us”.


Corpower Ocean will carry out tests off the Orkney Islands in Scotland later this year. If successful it will be a huge industrial breakthrough and the map of global energy supply will be redrawn.
