How Waves Could Quietly Overtake Solar & Wind. Every crashing wave delivers a pulse of power. Add them all up, and the ocean carries more energy than the roughly 30,000 TWh of electricity generated globally in 2023. But for decades, wave power has been a sea of broken dreams. But in 2023, buoys from a Swedish company called CorPower survived record-breaking 60-foot waves — and kept sending clean power to the grid. With costs plunging and the first full wave farms on the horizon, a decades-old dream might finally be about to break through. So the question is: Is wave energy finally ready for prime time — or will it be just another shipwreck in the history of clean power?

Là in mezzo al mar c’è una boa che produce energia.

E’ il progetto della società svedese CorPower che utilizza il movimento delle onde dell’oceano. Una boa larga 8 metri riesce a fornire energia idroelettrica per 250 kilowatt di potenza a circa 200 abitazioni. L’idea nasce dall’emulazione del movimento del cuore umano e la capacità di assorbire energia in maniera combinata sia dalla corrente superficiale che dal movimento di sollevamento delle onde. I progettisti svedesi sostengono che la creazione di centinaia di boe porterebbe alla produzione di energia elettrica pulita per interi quartieri e stimano che il 10-20% per cento del totale di energia elettrica sulla Terra potrebbe essere alimentata attraverso l‘energia delle onde.

The global wave energy market was valued at USD 43.8 million in 2019 and is projected to reach USD 141.1 million by the year 2027, expanding at a CAGR of 17.8% during the forecast period, 2021-2028.

Based on locations, the market can be segregated into onshore, near shore, and offshore. The near shore segment is anticipated to continue to grow, due to the ease and low cost of installation, high operational efficiency, dual use of application (power generation and desalination) at the same time, and increase in the number of patents to harness energy.

The Wonder-Buoy That May Finally Make Wave Energy Feasible

The Wonder-Buoy That May Finally Make Wave Energy Feasible

  WITH ALL THAT to-and-fro and ebb-and-flow, the motions of the ocean offer an endless supply of renewable energy. Or they would, if engineers could figure out how to capture that power. Most prototypes for wave-energy converters have been massive and costly, or else they’re torn apart during violent storms at sea. But a Swedish company called CorPower Ocean may finally have a solution. Tests…

Gear technology helps lower cost of wave energy farming

A Swedish company has cracked the challenge of scaling up wave energy, with the help of technology from researchers at KTH Royal Institute of Technology.

CorPower Ocean’s new wave energy system, which uses a gearbox design that KTH researchers helped develop, generates five times more energy per ton of device, at one third of the cost when compared to competing state-of-the art technologies. Energy output is three to four times higher than traditional wave power systems.

The company’s innovation was recently awarded EUR 100,000 at the MIT Building Global Innovators Demo Day.

Wave energy has been held back in part because of the cost of electricity generation. The amount of steel and concrete needed in order to produce each MWh has simply been too great to make it into a profitable business. Even still, the power of waves presents a problem with reliability; and because waves vary greatly in height and timing, it’s difficult to create a conversion system that functions across the full wave spectrum.

Known in the wave energy industry as a point absorber type system, the CorPower converter consists of a buoy that absorbs energy from the waves, plus a drivetrain that converts the buoy’s motion into electricity. The company’s system is based on Swedish cardiologist Stig Lundbäck’ patents, some of which are inspired by his research into heart pumping and control functions.
